impl Block for AutocryptCipher

fn encrypt(&self, dst: &mut [u8], src: &[u8]) -> usize

Encrypts plaintext using the Autocrypt cipher with ciphertext feedback.

This method implements the autocrypt encryption scheme where:

• The first key.len() characters are encrypted using the original key
• Subsequent characters use previously generated ciphertext as the key (CBC-like mode)

Arguments

• dst - The destination buffer where ciphertext will be written
• src - The source plaintext to encrypt (assumes uppercase A-Z characters)

Returns

The number of bytes written to dst, which is min(src.len(), dst.len())

Example

use old_crypto_rs::AutocryptCipher;
use old_crypto_rs::Block;

let cipher = AutocryptCipher::new("KEY");
let plaintext = b"HELLO";
let mut ciphertext = vec![0u8; plaintext.len()];
cipher.encrypt(&mut ciphertext, plaintext);
assert_eq!(&ciphertext, b"RIJCW");

fn decrypt(&self, dst: &mut [u8], src: &[u8]) -> usize

Decrypts ciphertext using the Autocrypt cipher with ciphertext feedback.

This method implements the autocrypt decryption scheme where:

• The first key.len() characters are decrypted using the original key
• Subsequent characters use previously processed ciphertext as the key (CBC-like mode)

Arguments

• dst - The destination buffer where plaintext will be written
• src - The source ciphertext to decrypt (assumes uppercase A-Z characters)

Returns

The number of bytes written to dst, which is min(src.len(), dst.len())

Example

use old_crypto_rs::AutocryptCipher;
use old_crypto_rs::Block;

let cipher = AutocryptCipher::new("KEY");
let ciphertext = b"RIJCW";
let mut plaintext = vec![0u8; ciphertext.len()];
cipher.decrypt(&mut plaintext, ciphertext);
assert_eq!(&plaintext, b"HELLO");
