Struct JournalXtsCipher 

pub struct JournalXtsCipher { /* private fields */ }

Cipher used for encrypting and decrypting journal mutations with AES-256-XTS and CTS.

Implementations

impl JournalXtsCipher

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

pub fn encrypt(&mut self, buffer: &[u8]) -> Vec<u8>

Encrypts buffer using AES-256-XTS with ciphertext stealing into a newly allocated vector. If buffer.len() < 16, it will be zero-padded to 16 bytes first.

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

Decrypts buffer in place using AES-256-XTS with ciphertext stealing. buffer.len() must be >= 16.

pub fn current_tweak(&self) -> u64

pub fn key_is_new(&self) -> bool
