Expand description

Synchronous stream cipher core trait.

Required methods

Apply keystream to inout data.

If end of the keystream will be achieved with the given data length, method will return StreamCipherError without modifying provided data.

Provided methods

Apply keystream to data behind buf.

If end of the keystream will be achieved with the given data length, method will return StreamCipherError without modifying provided data.

Apply keystream to inout data.

It will XOR generated keystream with the data behind in pointer and will write result to out pointer.

Panics

If end of the keystream will be reached with the given data length, method will panic without modifying the provided data.

Apply keystream to data in-place.

It will XOR generated keystream with data and will write result to the same buffer.

Panics

If end of the keystream will be reached with the given data length, method will panic without modifying the provided data.

Apply keystream to data buffer-to-buffer.

It will XOR generated keystream with data from the input buffer and will write result to the output buffer.

Returns StreamCipherError if provided in_blocks and out_blocks have different lengths or if end of the keystream will be reached with the given input data length.
