}

Decrypt-only functionality for block ciphers and modes with mutable access to self.

The main use case for this trait is blocks modes, but it also can be used for hardware cryptographic engines which require &mut self access to an underlying hardware peripheral.

Required Methods

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

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

Provided Methods

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

Decrypt single inout block.

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

Decrypt inout blocks.

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

Decrypt single block in-place.

fn decrypt_block_b2b_mut(
    &mut self,
    in_block: &Block<Self>,
    out_block: &mut Block<Self>
)

Decrypt in_block and write result to out_block.

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

Decrypt blocks in-place.

fn decrypt_blocks_b2b_mut(
    &mut 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_mut<'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_mut<P: Padding<Self::BlockSize>>(
    self,
    buf: &mut [u8]
) -> Result<&[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_mut<'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_mut<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.
