tc_tea
Rusty implementation of Tencent modified TEA (tc_tea).
Test data generated using its C++ implementation: tc_tea.cpp (BSD-3-Clause).
Code implemented according to the spec described in iweizime/StepChanger:腾讯 TEA 加密算法.
Features
random
(default:on
): Enable RNG when generating padding bytes for tc_tea.random_secure
(default:on
): Use a secure RNG when generating padding bytes for tc_tea.
If you don't expect to encrypt anything, you can specify default-features = false
to drop RNG support.
In this case, it will use a pre-generated deterministic salt.
Install
Add the following to [dependencies]
section in your Cargo.toml
file:
tc_tea = "0.2"
Usage
use tc_tea;
fn hello_tc_tea() {
let key = b"12345678ABCDEFGH";
let encrypted = tc_tea::encrypt(&"hello", &key).unwrap();
let decrypted = tc_tea::decrypt(&encrypted, &key).unwrap();
assert_eq!("hello", std::str::from_utf8(&decrypted).unwrap());
}
