Struct Cipher

pub struct Cipher<C>
where
    C: BlockCipher<BlockSize = U16>,
{ /* private fields */ }

Cipher is an instance of the HCTR2 cipher.

Implementations

impl<C> Cipher<C>

where C: BlockCipher<BlockSize = U16> + BlockEncrypt + BlockDecrypt,

pub fn encrypt(&mut self, ciphertext: &mut [u8], plaintext: &[u8], tweak: &[u8])

Encrypts plaintext into ciphertext using tweak.

It panics if either plaintext or ciphertext are less than BLOCK_SIZE bytes.

pub fn decrypt(&mut self, plaintext: &mut [u8], ciphertext: &[u8], tweak: &[u8])

Decrypts ciphertext into plaintext using tweak.

It panics if either ciphertext or plaintext are less than BLOCK_SIZE bytes.

pub fn encrypt_in_place(&mut self, plaintext: &mut [u8], tweak: &[u8])

Encrypts plaintext in-place using tweak.

It panics if plaintext is less than BLOCK_SIZE bytes.

pub fn decrypt_in_place(&mut self, ciphertext: &mut [u8], tweak: &[u8])

Decrypts ciphertext in-place using tweak.

It panics if ciphertext is less than BLOCK_SIZE bytes.

Trait Implementations

impl<C> Clone for Cipher<C>

where C: BlockCipher<BlockSize = U16> + Clone,

fn clone(&self) -> Cipher<C>

Returns a duplicate of the value.

const fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<C> Drop for Cipher<C>

where C: BlockCipher<BlockSize = U16>,

Available on crate feature zeroize only.

fn drop(&mut self)

Executes the destructor for this type.

impl<C> KeyInit for Cipher<C>

where C: BlockCipher<BlockSize = U16> + BlockEncrypt + KeyInit,

fn new(key: &Key<C>) -> Self

new creates an HCTR2 cipher.

The provided block cipher must have a block size of exactly BLOCK_SIZE bytes.

Create new value from variable size key.

impl<C> KeySizeUser for Cipher<C>

where C: BlockCipher<BlockSize = U16> + KeyInit,

type KeySize = <C as KeySizeUser>::KeySize

Key size in bytes.

fn key_size() -> usize

Return key size in bytes.

impl<C> ZeroizeOnDrop for Cipher<C>

where C: BlockCipher<BlockSize = U16>,

Available on crate feature zeroize only.
