Trait StreamCipher 

pub trait StreamCipher {
    type Key: AsRef<[u8]>;
    type Nonce: AsRef<[u8]>;

    // Required methods
    fn new(key: &Self::Key, iv: &Self::Nonce) -> Self;
    fn apply_keystream(&mut self, buffer: &mut [u8]) -> Result<(), CipherError>;
}

Synchronous stream cipher trait.

Required Associated Types

type Key: AsRef<[u8]>

The byte array key type which specifies the size of the key used to instantiate the cipher.

type Nonce: AsRef<[u8]>

The byte array nonce type which specifies the size of the nonce used in the cipher operations.

Required Methods

fn new(key: &Self::Key, iv: &Self::Nonce) -> Self

Instantiate a new instance of a stream cipher from a key and iv.

fn apply_keystream(&mut self, buffer: &mut [u8]) -> Result<(), CipherError>

Applies the cipher keystream to buffer in place, returning CipherError on an unsuccessful operation.

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.
