Struct fxfs_crypto::StreamCipher

pub struct StreamCipher(/* private fields */);

A thin wrapper around a ChaCha20 stream cipher. This will use a zero nonce. NOTE: Great care must be taken not to encrypt different plaintext with the same key and offset (even across multiple boots), so consider if this suits your purpose before using it.

Implementations

impl StreamCipher

pub fn new(key: &UnwrappedKey, offset: u64) -> Self

pub fn encrypt(&mut self, buffer: &mut [u8])

pub fn decrypt(&mut self, buffer: &mut [u8])

pub fn offset(&self) -> u64
