老哥 我用了你发的 怎么老是说不合法呢 let text=String::from("12312312"); let keytext=String::from("12345678123456781234567812345678"); let iv=String::from("1234567812345678"); let dtext =encrypt(text,keytext,iv); println!("{:?}",dtext); 32位key和16位iv哪里错了 thread 'main' panicked at 'called Result::unwrap() on an Err value: InvalidKeyIvLength', src/untils/aes.rs:14:56

}

碰巧跟你有过同样的需求，这是我之前弄的，希望能帮到你。

let key = kv_pair[0].trim().as_bytes();
let iv = kv_pair[1].trim().as_bytes();
let cipher_4_dec = Aes128Cbc::new_var(key, iv).expect("Initial cipher fail");

好像有个.bytes()
