Rust库学习-cipher(AES128简单使用)

介绍

cipher是Rust的一个密码库
AES128中key和block的长度都是128bit(即128(bit)/8(一个字节8bit)=16个字节)
所以下文中GenericArray::from固定长度为16位

实践

Cargo.toml

[dependencies]
aes = "0.8.2"
base64 = "0.13.1"
cipher = "0.4.3"

main.rs

use aes::cipher::{generic_array::GenericArray, BlockEncrypt, KeyInit,BlockDecrypt};
use aes::Aes128;
fn main() {
    let test = "0000000000000000";
    let test = test.as_bytes();

    println!("test: {:?}", test);

    let key = GenericArray::from([48u8; 16]);
    let mut block = GenericArray::from([48u8; 16]);
    // Initialize cipher
    let cipher = Aes128::new(&key);
    // Encrypt block in-place
    println!("明文: {:?}", block);
    cipher.encrypt_block(&mut block);
    println!("密文: {:?}", base64::encode(block));

    cipher.decrypt_block(&mut block);
    println!("明文: {:?}", std::str::from_utf8(&block));
}
