OFB (Output FeedBack) is one of the operation modes for encryption/decryption.

Required Methods

fn encrypt( &mut self, iv: T, message: *const u8, length_in_bytes: u64, cipher: *mut u8, ) -> u64

Encrypts the data without any padding in OFB (Output FeedBack) mode.

Arguments

• iv is an initialization vector for OFB mode.
• message is an immutable pointer to u8 which is *const u8, and is the place where the plaintext to be encrypted is stored.
• length_in_bytes is of u64-type, and is the length of the plaintext message in bytes.
• cipher is a mutable pointer to u8 which is *mut u8, and is the place where the encrypted data will be stored.

Output

• This method returns the size of ciphertext.
• If this method failed in encryption or length_in_bytes is 0, this method returns zero.

Features

• You are not encouraged to use this method in pure Rust programming. Instead, use other safer methods such as encrypt_*_into_*().
• This method is useful to use in hybrid programming with C/C++.
• If length_in_bytes is 0, it means the message is null string. So, nothing will be encrypted, and stored in the memory area that starts from cipher.
• The size of the memory area which starts at cipher is assumed to be enough to store the ciphertext.
• The size of the area for ciphertext should be prepared to be the same as length_in_bytes at least. So, it is responsible for you to prepare the cipher area big enough!

fn encrypt_into_vec<U>( &mut self, iv: T, message: *const u8, length_in_bytes: u64, cipher: &mut Vec<U>, ) -> u64

where U: SmallUInt + Copy + Clone,

Encrypts the data without any padding in OFB (Output FeedBack) mode, and stores the encrypted data in Vec<U>.

Arguments

• iv is an initialization vector for OFB mode.
• message is an immutable pointer to u8 which is *const u8, and is the place where the plaintext to be encrypted is stored.
• length_in_bytes is of u64-type, and is the length of the plaintext message in bytes.
• cipher is a mutable reference to Vec<U> object, and is the place where the encrypted data will be stored.

Output

• This method returns the size of ciphertext.
• If this method failed in encryption or length_in_bytes is 0, this method returns zero.

Features

• You are not encouraged to use this method in pure Rust programming. Instead, use other safer methods such as encrypt_*_into_vec().
• This method is useful to use in hybrid programming with C/C++.
• If length_in_bytes is 0, it means the message is a null string. So, nothing will be encrypted, and stored in the Vec<U> object which is referred to as cipher.
• You don’t have to worry about whether or not the size of the memory area where the ciphertext will be stored is enough.

fn encrypt_into_array<U, const N: usize>( &mut self, iv: T, message: *const u8, length_in_bytes: u64, cipher: &mut [U; N], ) -> u64

where U: SmallUInt + Copy + Clone,

Encrypts the data without any padding in OFB (Output FeedBack) mode, and stores the encrypted data in array [U; N].

Arguments

• iv is an initialization vector for OFB mode.
• message is an immutable pointer to u8 which is *const u8, and is the place where the plaintext to be encrypted is stored.
• length_in_bytes is of u64-type, and is the length of the plaintext message in bytes.
• cipher is a mutable reference to an array [U; N] object, and is the place where the encrypted data will be stored.

Output

• This method returns the size of ciphertext.
• If this method failed in encryption or length_in_bytes is 0, this method returns zero.

Features

• You are not encouraged to use this method in pure Rust programming. Instead, use other safer methods such as encrypt_*_into_array().
• This method is useful to use in hybrid programming with C/C++.
• If length_in_bytes is 0, it means the message is null data. So, nothing will be encrypted, and stored in the array [U; N] object cipher.
• If U::size_in_bytes() * N is less than length_in_bytes, this method does not perform encryption but returns zero.
• If U::size_in_bytes() * N is equal to length_in_bytes, this method performs encryption, fills the array cipher with the encrypted data, and returns the size of the ciphertext in bytes.
• If U::size_in_bytes() * N is greater than length_in_bytes, this method performs encryption, fills the array cipher with the encrypted data, and then fills the rest of the elements of the array cipher with zeros, and returns the size of the ciphertext in bytes.
• The size of the area for ciphertext should be prepared to be the same as length_in_bytes at least. So, it is responsible for you to prepare the cipher area big enough!

fn decrypt_into_array<U, const N: usize>( &mut self, iv: T, cipher: *const u8, length_in_bytes: u64, message: &mut [U; N], ) -> u64

where U: SmallUInt + Copy + Clone,

Decrypts the data without any padding in OFB (Output FeedBack) mode, and stores the decrypted data in array [U; N].

Arguments

• iv is an initialization vector for OFB mode.
• cipher is an immutable pointer to u8 which is *const u8, and is the place where the ciphertext to be decrypted is stored.
• length_in_bytes is of u64-type, and is the length of the ciphertext cipher in bytes.
• message is a mutable reference to an array [U; N] object, and is the place where the decrypted data will be stored.

Output

• This method returns the size of plaintext in bytes.
• If this method failed in decryption, it always returns zero.
• Even if this method succeeded in decryption, it returns zero when the original plaintext is zero-length empty data. Then, you will have to check whether or not it failed by using the method is_successful() or is_failed().
• If length_in_bytes is greater than 0 (which means that the original plaintext is surely not empty data) and it returns zero, you can interpret it that this method surely failed in decryption.

Features

• You are not encouraged to use this method in pure Rust programming. Instead, use other safer methods such as decrypt_*_into_array().
• This method is useful to use in hybrid programming with C/C++.

Provided Methods

fn encrypt_str(&mut self, iv: T, message: &str, cipher: *mut u8) -> u64

Encrypts the data in a str object without any padding in OFB (Output FeedBack) mode.

Arguments

• iv is an initialization vector for OFB mode.
• message is an immutable reference to str object which is &str, and is the place where the plaintext to be encrypted is stored.
• cipher is a mutable pointer to u8 which is *mut u8, and is the place where the encrypted data will be stored.

Output

• This method returns the size of ciphertext.
• If this method failed in encryption or message.len() is 0, this method returns zero.

Features

• You are not encouraged to use this method in pure Rust programming. Instead, use other safer methods such as encrypt_str_into_*().
• This method is useful to use in hybrid programming with C/C++.
• If message is a null string “”, nothing will be encrypted, and stored in the memory area that starts from cipher.
• The size of the memory area which starts at cipher is assumed to be enough to store the ciphertext.
• The size of the area for ciphertext should be prepared to be message.len() at least. So, it is responsible for you to prepare the cipher area big enough!

fn encrypt_str_into_vec<U>( &mut self, iv: T, message: &str, cipher: &mut Vec<U>, ) -> u64

where U: SmallUInt + Copy + Clone,

Encrypts the data in str without any padding in OFB (Output FeedBack) mode, and stores the encrypted data in Vec<U>.

Arguments

• iv is an initialization vector for OFB mode.
• message is an immutable reference to str object which is &str, and is the place where the plaintext to be encrypted is stored.
• cipher is a mutable reference to Vec<U> object, and is the place where the encrypted data will be stored.

Output

• This method returns the size of ciphertext.
• If this method failed in encryption or message.len() is 0, this method returns zero.

Features

• If message is a null string “”, nothing will be encrypted, and stored in the Vec<U> object which is referred to as cipher.
• You don’t have to worry about whether or not the size of the memory area where the ciphertext will be stored is enough.

fn encrypt_str_into_array<U, const N: usize>( &mut self, iv: T, message: &str, cipher: &mut [U; N], ) -> u64

where U: SmallUInt + Copy + Clone,

Encrypts the data in a str object without any padding in OFB (Output FeedBack) mode, and stores the encrypted data in array [U; N].

Arguments

• iv is an initialization vector for OFB mode.
• message is an immutable reference to str object which is &str, and is the place where the plaintext to be encrypted is stored.
• cipher is a mutable reference to an array [U; N] object, and is the place where the encrypted data will be stored.

Output

• This method returns the size of ciphertext.
• If this method failed in encryption or message.len() is 0, this method returns zero.

Features

• If message is a null string “”, nothing will be encrypted, and stored in the array [U; N] object cipher.
• If U::size_in_bytes() * N is less than message.len(), this method does not perform encryption but returns zero.
• If U::size_in_bytes() * N is equal to message.len(), this method performs encryption, fills the array cipher with the encrypted data, and returns the size of the ciphertext in bytes.
• If U::size_in_bytes() * N is greater than message.len(), this method performs encryption, fills the array cipher with the encrypted data, and then fills the rest of the elements of the array cipher with zeros, and returns the size of the ciphertext in bytes.
• The size of the area for ciphertext should be prepared to be message.len() at least. So, it is responsible for you to prepare the cipher area big enough!

fn encrypt_string(&mut self, iv: T, message: &String, cipher: *mut u8) -> u64

Encrypts the data stored in a String object without any padding in OFB (Output FeedBack) mode.

Arguments

• iv is an initialization vector for OFB mode.
• message is an immutable reference to String object, and is the place where the plaintext to be encrypted is stored.
• cipher is a mutable pointer to u8 which is *mut u8, and is the place where the encrypted data will be stored.

Output

• This method returns the size of ciphertext.
• If this method failed in encryption or message.len() is 0, this method returns zero.

Features

• You are not encouraged to use this method in pure Rust programming. Instead, use other safer methods such as encrypt_string_into_*().
• This method is useful to use in hybrid programming with C/C++.
• If message is a String object that has a null string “”, nothing will be encrypted, and stored in the memory area that starts from cipher.
• The size of the memory area which starts at cipher is assumed to be enough to store the ciphertext.
• The size of the area for ciphertext should be prepared to be message.len() at least. So, it is responsible for you to prepare the cipher area big enough!

fn encrypt_string_into_vec<U>( &mut self, iv: T, message: &String, cipher: &mut Vec<U>, ) -> u64

where U: SmallUInt + Copy + Clone,

Encrypts the data stored in a String object without any padding in OFB (Output FeedBack) mode, and stores the encrypted data in Vec<U>.

Arguments

• iv is an initialization vector for OFB mode.
• message is an immutable reference to String object, and is the place where the plaintext to be encrypted is stored.
• cipher is a mutable reference to Vec<U> object, and is the place where the encrypted data will be stored.

Output

• This method returns the size of ciphertext.
• If this method failed in encryption or message.len() is 0, this method returns zero.

Features

• If message is a String object that has a null string “”, nothing will be encrypted, and stored in the Vec<U> object which is referred to as cipher.
• You don’t have to worry about whether or not the size of the memory area where the ciphertext will be stored is enough.

fn encrypt_string_into_array<U, const N: usize>( &mut self, iv: T, message: &String, cipher: &mut [U; N], ) -> u64

where U: SmallUInt + Copy + Clone,

Encrypts the data stored in a String object without any padding in OFB (Output FeedBack) mode, and stores the encrypted data in array [U; N].

Arguments

• iv is an initialization vector for OFB mode.
• message is an immutable reference to String object, and is the place where the plaintext to be encrypted is stored.
• cipher is a mutable reference to an array [U; N] object, and is the place where the encrypted data will be stored.

Output

• This method returns the size of ciphertext.
• If this method failed in encryption or message.len() is 0, this method returns zero.

Features

• If message is a String object that has a null string “”, nothing will be encrypted, and stored in the array [U; N] object cipher.
• If U::size_in_bytes() * N is less than message.len(), this method does not perform encryption but returns zero.
• If U::size_in_bytes() * N is equal to message.len(), this method performs encryption, fills the array cipher with the encrypted data, and returns the size of the ciphertext in bytes.
• If U::size_in_bytes() * N is greater than message.len(), this method performs encryption, fills the array cipher with the encrypted data, and then fills the rest of the elements of the array cipher with zeros, and returns the size of the ciphertext in bytes.
• The size of the area for ciphertext should be prepared to be message.len() at least. So, it is responsible for you to prepare the cipher area big enough!

fn encrypt_vec<U>(&mut self, iv: T, message: &Vec<U>, cipher: *mut u8) -> u64

where U: SmallUInt + Copy + Clone,

Encrypts the data stored in a Vec<U> object without any padding in OFB (Output FeedBack) mode.

Arguments

• iv is an initialization vector for OFB mode.
• message is an immutable reference to Vec<U> object, and is the place where the plaintext to be encrypted is stored.
• cipher is a mutable pointer to u8 which is *mut u8, and is the place where the encrypted data will be stored.

Output

• This method returns the size of ciphertext.
• If this method failed in encryption or message.len() is 0, this method returns zero.

Features

• You are not encouraged to use this method in pure Rust programming. Instead, use other safer methods such as encrypt_vec_into_*().
• This method is useful to use in hybrid programming with C/C++.
• The size of the memory area which starts at cipher is assumed to be enough to store the ciphertext.
• The size of the area for ciphertext should be prepared to be size_of::<U>() * message.len() at least. So, it is responsible for you to prepare the cipher area big enough!
• If message is an empty Vec<U> object Vec::<U>::new(), nothing will be encrypted, and stored in the memory area that starts from cipher.

fn encrypt_vec_into_vec<U, V>( &mut self, iv: T, message: &Vec<U>, cipher: &mut Vec<V>, ) -> u64

where U: SmallUInt + Copy + Clone, V: SmallUInt + Copy + Clone,

Encrypts the data stored in a Vec<U> object without any padding in OFB (Output FeedBack) mode, and stores the encrypted data in Vec<V>.

Arguments

• iv is an initialization vector for OFB mode.
• message is an immutable reference to Vec<U> object, and is the place where the plaintext to be encrypted is stored.
• cipher is a mutable reference to Vec<U> object, and is the place where the encrypted data will be stored.

Output

• This method returns the size of ciphertext.
• If this method failed in encryption or message.len() is 0, this method returns zero.

Features

• If message is an empty Vec<U> object Vec::<U>::new(), nothing will be encrypted, and stored in the Vec<U> object which is referred to as cipher.
• You don’t have to worry about whether or not the size of the memory area where the ciphertext will be stored is enough.

fn encrypt_vec_into_array<U, V, const N: usize>( &mut self, iv: T, message: &Vec<U>, cipher: &mut [V; N], ) -> u64

where U: SmallUInt + Copy + Clone, V: SmallUInt + Copy + Clone,

Encrypts the data stored in a Vec<U> object without any padding in OFB (Output FeedBack) mode, and stores the encrypted data in array [V; N].

Arguments

• iv is an initialization vector for OFB mode.
• message is an immutable reference to Vec<U> object, and is the place where the plaintext to be encrypted is stored.
• cipher is a mutable reference to an array [U; N] object, and is the place where the encrypted data will be stored.

Output

• This method returns the size of ciphertext.
• If this method failed in encryption or message.len() is 0, this method returns zero.

Features

• If message is an empty Vec<U> object Vec::<U>::new(), nothing will be encrypted, and stored in the array [U; N] object cipher.
• If size_of::<V>() * N is less than size_of::<U>() * message.len(), this method does not perform encryption but returns zero.
• If size_of::<V>() * N is equal to size_of::<U>() * message.len(), this method performs encryption, fills the array cipher with the encrypted data, and returns the size of the ciphertext in bytes.
• If size_of::<V>() * N is greater than size_of::<U>() * message.len(), this method performs encryption, fills the array cipher with the encrypted data, and then fills the rest of the elements of the array cipher with zeros, and returns the size of the ciphertext in bytes.
• The size of the area for ciphertext should be prepared to be size_of::<U>() * message.len() at least. So, it is responsible for you to prepare the cipher area big enough!

fn encrypt_array<U, const N: usize>( &mut self, iv: T, message: &[U; N], cipher: *mut u8, ) -> u64

where U: SmallUInt + Copy + Clone,

Encrypts the data stored in an array [U; N] object without any padding in OFB (Output FeedBack) mode.

Arguments

• iv is an initialization vector for OFB mode.
• message is an immutable reference to an array [U; N] object, and is the place where the plaintext to be encrypted is stored.
• cipher is a mutable pointer to u8 which is *mut u8, and is the place where the encrypted data will be stored.

Output

• This method returns the size of ciphertext.
• If this method failed in encryption or message.len() is 0, this method returns zero.

Features

• You are not encouraged to use this method in pure Rust programming. Instead, use other safer methods such as encrypt_vec_into_*().
• This method is useful to use in hybrid programming with C/C++.
• The size of the memory area which starts at cipher is assumed to be enough to store the ciphertext.
• The size of the area for ciphertext should be prepared to be size_of::<U>() * N at least. So, it is responsible for you to prepare the cipher area big enough!
• If message is an empty array [U; 0] object, nothing will be encrypted, and stored in the memory area that starts from cipher.

fn encrypt_array_into_vec<U, V, const N: usize>( &mut self, iv: T, message: &[U; N], cipher: &mut Vec<V>, ) -> u64

where U: SmallUInt + Copy + Clone, V: SmallUInt + Copy + Clone,

Encrypts the data stored in an array [U; N] object without any padding in OFB (Output FeedBack) mode, and stores the encrypted data in Vec<V>.

Arguments

• iv is an initialization vector for OFB mode.
• message is an immutable reference to an array [U; N] object, and is the place where the plaintext to be encrypted is stored.
• cipher is a mutable reference to Vec<U> object, and is the place where the encrypted data will be stored.

Output

• This method returns the size of ciphertext.
• If this method failed in encryption or message.len() is 0, this method returns zero.

Features

• If message is an empty array [U; 0] object, nothing will be encrypted, and stored in the Vec<U> object cipher.
• You don’t have to worry about whether or not the size of the memory area where the ciphertext will be stored is enough.

fn encrypt_array_into_array<U, V, const N: usize, const M: usize>( &mut self, iv: T, message: &[U; N], cipher: &mut [V; M], ) -> u64

where U: SmallUInt + Copy + Clone, V: SmallUInt + Copy + Clone,

Encrypts the data stored in an array [U; N] object without any padding in OFB (Output FeedBack) mode, and stores the encrypted data in array [V; M].

Arguments

• iv is an initialization vector for OFB mode.
• message is an immutable reference to an array [U; N] object, and is the place where the plaintext to be encrypted is stored.
• cipher is a mutable reference to an array [V; M] object, and is the place where the encrypted data will be stored.

Output

• This method returns the size of ciphertext.
• If this method failed in encryption or message.len() is 0, this method returns zero.

Features

• If message is an empty array [U; 0] object, nothing will be encrypted, and stored in the array [V; M] object cipher.
• If V::size_in_bytes() * M is less than U::size_in_bytes() * N, this method does not perform encryption and returns zero.
• If V::size_in_bytes() * M is equal to U::size_in_bytes() * N, this method performs encryption, fills the array cipher with the encrypted ciphertext, and returns the size of the ciphertext in bytes.
• If V::size_in_bytes() * M is greater than U::size_in_bytes() * N, this method performs encryption, fills the array cipher with the encrypted ciphertext, and then fills the rest of the elements of the array cipher with zeros, and returns the size of the ciphertext in bytes.
• The size of the area for ciphertext should be prepared to be size_of::<U>() * message.len() at least. So, it is responsible for you to prepare the cipher area big enough!

fn decrypt( &mut self, iv: T, cipher: *const u8, length_in_bytes: u64, message: *mut u8, ) -> u64

Decrypts the data without any padding in OFB (Output FeedBack) mode.

Arguments

• iv is an initialization vector for OFB mode.
• cipher is an immutable pointer to u8 which is *const u8, and is the place where the ciphertext to be decrypted is stored.
• length_in_bytes is of u64-type, and is the length of the ciphertext cipher in bytes.
• message is a mutable pointer to u8 which is *mut u8, and is the place where the decrypted data will be stored.

Output

• This method returns the size of plaintext in bytes.
• If this method failed in decryption, it always returns zero.
• Even if this method succeeded in decryption, it returns zero when the original plaintext is zero-length empty data. Then, you will have to check whether or not it failed by using the method is_successful() or is_failed().
• If length_in_bytes is greater than 0 (which means that the original plaintext is surely not empty data) and it returns zero, you can interpret it that this method surely failed in decryption.

Features

• You are not encouraged to use this method in pure Rust programming. Instead, use other safer methods such as decrypt_*_into_*().
• This method is useful to use in hybrid programming with C/C++.
• The size of the memory area which starts at message is assumed to be enough to store the plaintext. So, it is responsible for you to prepare the message area big enough!
• The size of the area for plaintext does not have to be prepared more than length_in_bytes.
• If the size of the area for plaintext is prepared more than length_in_bytes, the rest of the area will be filled with 0s.

fn decrypt_into_vec<U>( &mut self, iv: T, cipher: *const u8, length_in_bytes: u64, message: &mut Vec<U>, ) -> u64

where U: SmallUInt + Copy + Clone,

Decrypts the data without any padding in OFB (Output FeedBack) mode, and stores the decrypted data in Vec<U>.

Arguments

• iv is an initialization vector for OFB mode.
• cipher is an immutable pointer to u8 which is *const u8, and is the place where the ciphertext to be decrypted is stored.
• length_in_bytes is of u64-type, and is the length of the ciphertext cipher in bytes.
• message is a mutable reference to Vec<U> object, and is the place where the decrypted data will be stored.

Output

• This method returns the size of plaintext in bytes.
• If this method failed in decryption, it always returns zero.
• Even if this method succeeded in decryption, it returns zero when the original plaintext is zero-length empty data. Then, you will have to check whether or not it failed by using the method is_successful() or is_failed().
• If length_in_bytes is greater than 0 (which means that the original plaintext is surely not empty data) and it returns zero, you can interpret it that this method surely failed in decryption.

Features

• You are not encouraged to use this method in pure Rust programming. Instead, use other safer methods such as decrypt_*_into_vec().
• This method is useful to use in hybrid programming with C/C++.
• You don’t have to worry about whether or not the size of the memory area where the plaintext will be stored is enough.

fn decrypt_into_string( &mut self, iv: T, cipher: *const u8, length_in_bytes: u64, message: &mut String, ) -> u64

Decrypts the data without any padding in OFB (Output FeedBack) mode, and stores the decrypted data in a String.

Arguments

• iv is an initialization vector for OFB mode.
• cipher is an immutable pointer to u8 which is *const u8, and is the place where the ciphertext to be decrypted is stored.
• length_in_bytes is of u64-type, and is the length of the ciphertext cipher in bytes.
• message is a mutable reference to a String object, and is the place where the decrypted data will be stored.

Output

• This method returns the size of plaintext in bytes.
• If this method failed in decryption, it always returns zero.
• Even if this method succeeded in decryption, it returns zero when the original plaintext is zero-length empty data. Then, you will have to check whether or not it failed by using the method is_successful() or is_failed().
• If length_in_bytes is greater than 0 (which means that the original plaintext is surely not empty data) and it returns zero, you can interpret it that this method surely failed in decryption.

Features

• You are not encouraged to use this method in pure Rust programming. Instead, use other safer methods such as decrypt_*_into_string().
• This method is useful to use in hybrid programming with C/C++.
• You don’t have to worry about whether or not the size of the memory area where the ciphertext will be stored is enough.
• This method assumes that the original plaintext is a string in the format of UTF-8.

fn decrypt_vec<U>(&mut self, iv: T, cipher: &Vec<U>, message: *mut u8) -> u64

where U: SmallUInt + Copy + Clone,

Decrypts the data stored in a Vec<U> object without any padding in OFB (Output FeedBack) mode.

Arguments

• iv is an initialization vector for OFB mode.
• cipher is an immutable reference to Vec<U> object, and is the place where the plaintext to be decrypted is stored.
• message is a mutable pointer to u8 which is *mut u8, and is the place where the decrypted data will be stored.

Output

• This method returns the size of plaintext in bytes.
• If this method failed in decryption, it always returns zero.
• Even if this method succeeded in decryption, it returns zero when the original plaintext is zero-length empty data. Then, you will have to check whether or not it failed by using the method is_successful() or is_failed().
• If size_of::<U>() * cipher.len() is greater than 0 (which means that the original plaintext is surely not empty data) and it returns zero, you can interpret it that this method surely failed in decryption.

Features

• You are not encouraged to use this method in pure Rust programming. Instead, use other safer methods such as decrypt_vec_into_*().
• This method is useful to use in hybrid programming with C/C++.
• The size of the memory area which starts at message is assumed to be enough to store the plaintext. So, it is responsible for you to prepare the message area big enough!
• The size of the area for plaintext does not have to be prepared more than size_of::<U>() * cipher.len().
• If the size of the area for plaintext is prepared more than size_of::<U>() * cipher.len(), the rest of the area will be filled with 0s.

fn decrypt_vec_into_vec<U, V>( &mut self, iv: T, cipher: &Vec<U>, message: &mut Vec<V>, ) -> u64

where U: SmallUInt + Copy + Clone, V: SmallUInt + Copy + Clone,

Decrypts the data stored in a Vec<U> object without any padding in OFB (Output FeedBack) mode, and stores the decrypted data in Vec<V>.

Arguments

• iv is an initialization vector for OFB mode.
• cipher is an immutable reference to Vec<U> object, and is the place where the ciphertext to be decrypted is stored.
• message is a mutable reference to Vec<U> object, and is the place where the decrypted data will be stored.

Output

• This method returns the size of plaintext in bytes.
• If this method failed in decryption, it always returns zero.
• Even if this method succeeded in decryption, it returns zero when the original plaintext is zero-length empty data. Then, you will have to check whether or not it failed by using the method is_successful() or is_failed().
• If size_of::<U>() * cipher.len() is greater than 0 (which means that the original plaintext is surely not empty data) and it returns zero, you can interpret it that this method surely failed in decryption.

Features

• You don’t have to worry about whether or not the size of the memory area where the ciphertext will be stored is enough.

fn decrypt_vec_into_array<U, V, const N: usize>( &mut self, iv: T, cipher: &Vec<U>, message: &mut [V; N], ) -> u64

where U: SmallUInt + Copy + Clone, V: SmallUInt + Copy + Clone,

Decrypts the data stored in a Vec<U> object without any padding in OFB (Output FeedBack) mode, and stores the decrypted data in array [V; N].

Arguments

• iv is an initialization vector for OFB mode.
• cipher is an immutable reference to Vec<U> object, and is the place where the ciphertext to be decrypted is stored.
• message is a mutable reference to an array [V; N] object, and is the place where the decrypted data will be stored.

Output

• This method returns the size of plaintext in bytes.
• If this method failed in decryption, it always returns zero.
• Even if this method succeeded in decryption, it returns zero when the original plaintext is zero-length empty data. Then, you will have to check whether or not it failed by using the method is_successful() or is_failed().
• If size_of::<U>() * cipher.len() is greater than 0 (which means that the original plaintext is surely not empty data) and it returns zero, you can interpret it that this method surely failed in decryption.

Features

• If size_of::<V>() * N is less than size_of::<U>() * cipher.len(), this method does not perform decryption but returns zero.
• If size_of::<V>() * N is equal to or greater than size_of::<U>() * cipher.len(), this method performs decryption, fills the array message with the decrypted data, and then fills the rest of the elements of the array message with zeros, and returns the size of the plaintext.
• It is responsible for you to prepare the message area big enough!
• The size of the area for plaintext does not have to be prepared more than size_of::<U>() * cipher.len().

fn decrypt_vec_into_string<U>( &mut self, iv: T, cipher: &Vec<U>, message: &mut String, ) -> u64

where U: SmallUInt + Copy + Clone,

Decrypts the data in str without any padding in OFB (Output FeedBack) mode, and stores the decrypted data in String.

Arguments

• iv is an initialization vector for OFB mode.
• cipher is an immutable reference to Vec<U> object, and is the place where the ciphertext to be decrypted is stored.
• message is a mutable reference to a String object, and is the place where the decrypted data will be stored.

Output

• This method returns the size of plaintext in bytes.
• If this method failed in decryption, it always returns zero.
• Even if this method succeeded in decryption, it returns zero when the original plaintext is zero-length empty data. Then, you will have to check whether or not it failed by using the method is_successful() or is_failed().
• If size_of::<U>() * cipher.len() is greater than 0 (which means that the original plaintext is surely not empty data) and it returns zero, you can interpret it that this method surely failed in decryption.

Features

• You don’t have to worry about whether or not the size of the memory area where the ciphertext will be stored is enough.
• This method assumes that the original plaintext is a string in the format of UTF-8.

fn decrypt_array<U, const N: usize>( &mut self, iv: T, cipher: &[U; N], message: *mut u8, ) -> u64

where U: SmallUInt + Copy + Clone,

Decrypts the data stored in an array [U; N] object without any padding in OFB (Output FeedBack) mode.

Arguments

• iv is an initialization vector for OFB mode.
• cipher is an immutable reference to an array [U; N] object, and is the place where the plaintext to be decrypted is stored.
• message is a mutable pointer to u8 which is *mut u8, and is the place where the decrypted data will be stored.

Output

• This method returns the size of plaintext in bytes.
• If this method failed in decryption, it always returns zero.
• Even if this method succeeded in decryption, it returns zero when the original plaintext is zero-length empty data. Then, you will have to check whether or not it failed by using the method is_successful() or is_failed().
• If size_of::<U>() * N is greater than 0 (which means that the original plaintext is surely not empty data) and it returns zero, you can interpret it that this method surely failed in decryption.

Features

• You are not encouraged to use this method in pure Rust programming. Instead, use other safer methods such as decrypt_array_into_*().
• This method is useful to use in hybrid programming with C/C++.
• The size of the memory area which starts at message is assumed to be enough to store the plaintext. So, it is responsible for you to prepare the message area big enough!
• The size of the area for plaintext does not have to be prepared more than size_of::<U>() * N.
• If the size of the area for plaintext is prepared more than size_of::<U>() * N, the rest of the area will be filled with 0s.

fn decrypt_array_into_vec<U, V, const N: usize>( &mut self, iv: T, cipher: &[U; N], message: &mut Vec<V>, ) -> u64

where U: SmallUInt + Copy + Clone, V: SmallUInt + Copy + Clone,

Decrypts the data stored in an array [U; N] object without any padding in OFB (Output FeedBack) mode, and stores the decrypted data in Vec<V>.

Arguments

• iv is an initialization vector for OFB mode.
• cipher is an immutable reference to an array [U; N] object, and is the place where the plaintext to be decrypted is stored.
• message is a mutable reference to Vec<U> object, and is the place where the decrypted data will be stored.

Output

• This method returns the size of plaintext in bytes.
• If this method failed in decryption, it always returns zero.
• Even if this method succeeded in decryption, it returns zero when the original plaintext is zero-length empty data. Then, you will have to check whether or not it failed by using the method is_successful() or is_failed().
• If size_of::<U>() * N is greater than 0 (which means that the original plaintext is surely not empty data) and it returns zero, you can interpret it that this method surely failed in decryption.

Features

• You don’t have to worry about whether or not the size of the memory area where the ciphertext will be stored is enough.

fn decrypt_array_into_array<U, V, const N: usize, const M: usize>( &mut self, iv: T, cipher: &[U; N], message: &mut [V; M], ) -> u64

where U: SmallUInt + Copy + Clone, V: SmallUInt + Copy + Clone,

Decrypts the data stored in an array [U; N] object without any padding in OFB (Output FeedBack) mode, and stores the decrypted data in array [V; M].

Arguments

• iv is an initialization vector for OFB mode.
• cipher is an immutable reference to an array [U; N] object, and is the place where the plaintext to be decrypted is stored.
• message is a mutable reference to an array [U; N] object, and is the place where the decrypted data will be stored.

Output

• This method returns the size of plaintext in bytes.
• If this method failed in decryption, it always returns zero.
• Even if this method succeeded in decryption, it returns zero when the original plaintext is zero-length empty data. Then, you will have to check whether or not it failed by using the method is_successful() or is_failed().
• If size_of::<U>() * N is greater than 0 (which means that the original plaintext is surely not empty data) and it returns zero, you can interpret it that this method surely failed in decryption.

Features

• If size_of::<V>() * M is less than size_of::<U>() * N, this method does not perform decryption but returns zero.
• If size_of::<V>() * M is equal to or greater than size_of::<U>() * N, this method performs decryption, fills the array message with the decrypted data, and then fills the rest of the elements of the array message with zeros, and returns the size of the plaintext.
• It is responsible for you to prepare the message area big enough!
• The size of the area for plaintext does not have to be prepared more than size_of::<U>() * N.

Arguments

• iv is an initialization vector for OFB mode.
• cipher is an immutable reference to an array [U; N] object, and is the place where the plaintext to be decrypted is stored.
• message is a mutable reference to a String object, and is the place where the decrypted data will be stored.

Output

• This method returns the size of plaintext in bytes.
• If this method failed in decryption, it always returns zero.
• Even if this method succeeded in decryption, it returns zero when the original plaintext is zero-length empty data. Then, you will have to check whether or not it failed by using the method is_successful() or is_failed().
• If size_of::<U>() * N is greater than 0 (which means that the original plaintext is surely not empty data) and it returns zero, you can interpret it that this method surely failed in decryption.

Features

• You don’t have to worry about whether or not the size of the memory area where the ciphertext will be stored is enough.
• This method assumes that the original plaintext is a string in the format of UTF-8.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
