Available on crate features aes or tdes only.

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 self, f: impl BlockModeDecClosure<BlockSize = Self::BlockSize>, )

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

Provided Methods

fn decrypt_block_inout( &mut self, block: InOut<'_, '_, Array<u8, Self::BlockSize>>, )

Decrypt single inout block.

fn decrypt_blocks_inout( &mut self, blocks: InOutBuf<'_, '_, Array<u8, Self::BlockSize>>, )

Decrypt inout blocks.

fn decrypt_block(&mut self, block: &mut Array<u8, Self::BlockSize>)

Decrypt single block in-place.

fn decrypt_block_b2b( &mut self, in_block: &Array<u8, Self::BlockSize>, out_block: &mut Array<u8, Self::BlockSize>, )

Decrypt in_block and write result to out_block.

fn decrypt_blocks(&mut self, blocks: &mut [Array<u8, Self::BlockSize>])

Decrypt blocks in-place.

fn decrypt_blocks_b2b( &mut self, in_blocks: &[Array<u8, Self::BlockSize>], out_blocks: &mut [Array<u8, Self::BlockSize>], ) -> Result<(), NotEqualError>

Decrypt blocks buffer-to-buffer.

Errors

Returns NotEqualError if provided in_blocks and out_blocks have different lengths.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
