Required methods

fn new(cipher: C, iv: &GenericArray<u8, Self::IvSize>) -> Self[src]

Create a new block mode instance from initialized block cipher and IV.

fn encrypt_blocks(
    &mut self,
    blocks: &mut [GenericArray<u8, <C as BlockCipher>::BlockSize>]
)
[src]

Encrypt blocks of data

fn decrypt_blocks(
    &mut self,
    blocks: &mut [GenericArray<u8, <C as BlockCipher>::BlockSize>]
)
[src]

Decrypt blocks of data

Provided methods

fn new_fix(
    key: &GenericArray<u8, <C as NewBlockCipher>::KeySize>,
    iv: &GenericArray<u8, Self::IvSize>
) -> Self where
    C: NewBlockCipher
[src]

Create a new block mode instance from fixed sized key and IV.

fn new_from_slices(key: &[u8], iv: &[u8]) -> Result<Self, InvalidKeyIvLength> where
    C: NewBlockCipher
[src]

Create a new block mode instance from variable size key and IV.

Returns an error if key or IV have unsupported length.

fn encrypt(self, buffer: &mut [u8], pos: usize) -> Result<&[u8], BlockModeError>[src]

Encrypt message in-place.

&buffer[..pos] is used as a message and &buffer[pos..] as a reserved space for padding. The padding space should be big enough for padding, otherwise method will return Err(BlockModeError).

fn decrypt(self, buffer: &mut [u8]) -> Result<&[u8], BlockModeError>[src]

Decrypt message in-place.

Returns an error if buffer length is not multiple of block size and if after decoding message has malformed padding.

fn encrypt_vec(self, plaintext: &[u8]) -> Vec<u8>

Notable traits for Vec<u8, A>

impl<A> Write for Vec<u8, A> where
    A: Allocator
[src]

Encrypt message and store result in vector.

fn decrypt_vec(self, ciphertext: &[u8]) -> Result<Vec<u8>, BlockModeError>[src]

Encrypt message and store result in vector.
