Decrypt-only functionality for block ciphers.

Required Methods

fn decrypt_with_backend( &self, f: impl BlockClosure<BlockSize = Self::BlockSize>, )

Decrypt data using backend provided to the rank-2 closure.

Provided Methods

fn decrypt_block_inout(&self, block: InOut<'_, '_, Block<Self>>)

Decrypt single inout block.

fn decrypt_blocks_inout(&self, blocks: InOutBuf<'_, '_, Block<Self>>)

Decrypt inout blocks.

fn decrypt_block(&self, block: &mut Block<Self>)

Decrypt single block in-place.

fn decrypt_block_b2b(&self, in_block: &Block<Self>, out_block: &mut Block<Self>)

Decrypt in_block and write result to out_block.

fn decrypt_blocks(&self, blocks: &mut [Block<Self>])

Decrypt blocks in-place.

fn decrypt_blocks_b2b( &self, in_blocks: &[Block<Self>], out_blocks: &mut [Block<Self>], ) -> Result<(), NotEqualError>

Decrypt blocks buffer-to-buffer.

Returns NotEqualError if provided in_blocks and out_blocks have different lengths.

fn decrypt_padded_inout<'inp, 'out, P: Padding<Self::BlockSize>>( &self, data: InOutBuf<'inp, 'out, u8>, ) -> Result<&'out [u8], UnpadError>

Decrypt input and unpad it. Returns resulting ciphertext slice.

Returns UnpadError if padding is malformed or if input length is not multiple of Self::BlockSize.

fn decrypt_padded<'a, P: Padding<Self::BlockSize>>( &self, buf: &'a mut [u8], ) -> Result<&'a [u8], UnpadError>

Decrypt input and unpad it in-place. Returns resulting ciphertext slice.

Returns UnpadError if padding is malformed or if input length is not multiple of Self::BlockSize.

fn decrypt_padded_b2b<'a, P: Padding<Self::BlockSize>>( &self, in_buf: &[u8], out_buf: &'a mut [u8], ) -> Result<&'a [u8], UnpadError>

Decrypt input and unpad it buffer-to-buffer. Returns resulting ciphertext slice.

Returns UnpadError if padding is malformed or if input length is not multiple of Self::BlockSize.

fn decrypt_padded_vec<P: Padding<Self::BlockSize>>( &self, buf: &[u8], ) -> Result<Vec<u8>, UnpadError>

Decrypt input and unpad it in a newly allocated Vec. Returns resulting ciphertext Vec.

Returns UnpadError if padding is malformed or if input length is not multiple of Self::BlockSize.
