A stateful (streaming) cipher interface

Required Methods

fn info(&self) -> CipherInfo

Returns information about the cipher

fn init( &mut self, key: &[u8], nonce: &[u8], ) -> Result<(), Box<dyn Error + 'static>>

(Re-)initializes the handle with key and nonce

fn update( &mut self, input: &[u8], output: impl Write, ) -> Result<usize, Box<dyn Error + 'static>>

Processes the bytes in input and writes the resulting bytes to output and returns the amount of bytes written

fn finish( &mut self, output: impl Write, ) -> Result<usize, Box<dyn Error + 'static>>

Finishes the operation and writes the pending bytes to output and returns the amount of bytes written

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
