Rust Encryption and Decryption
Usage
[dependencies]
encrypted_id = "0.1.4"
encrypted_id_derive = "0.1.0"
-
Encryption and Decryption in action
-
To make any struct encrypt-able, It must have an id field of type int(u64) necessary.
-
To make any struct encrypt-able or decrypt-able, It must define sub_key to encrypt and decrypt key individually.
-
Before using encrypt-able or decrypt-able, It must have initialize secret_key initially.
-
Secret key length depends upon how much good encryption that you want (64 byte recommended).
-
It is same as django encrypted_id.
-
We can reuse the secret key as we are using in django to en-decrypt the id.
-
In version 0.1.4, name changes crate Encrypted to Encrypt, crate Decrypted to Decrypt, function init_encrypt_conf to init_conf, struct function dkey to id. Made it independent crate, in earlier version it has a dependency of diesel-mate, In this version removed it. I will make sure that in future, I won't change any names, If so I'll deprecate first those.
#[macro_use]
extern crate encrypted_id_derive;
use encrypted_id::prelude::*;
#[derive(Debug, Default, Encrypt, Decrypt)]
#[encdec_opts(opts(sub_key = "enky_demo_sub_key"))]
pub struct Demo {
pub id: u64,
pub name: String,
}
//Deriving Encrypt trait for struct, it will generate a ekey function for this struct.
//Deriving Decrypt trait for struct, it will generate a id function for this struct.
fn enc_test() {
let e = Demo {
id: 5,
name: "foo".to_string(),
};
let ekey = e.ekey().unwrap();
let id = e.id(&ekey).unwrap();
assert_eq!("AuovBQ1f2B1AmEd3o0Uq1Q", ekey);
assert_eq!(5, id);
}
fn main(){
init_conf("df(vh!3*8e21@qca#3)w#7ta*z#!bhsde43&#iez3sf5m1#h6l");
enc_test()
}
Using without struct
#[test]
fn encrypt_id() {
init_conf("df(vh!3*8e21@qca#3)w#7ta*z#!bhsde43&#iez3sf5m1#h6l");
let ekey = encode(5, "sub_key_foo").unwrap();
let id = decode(&ekey, "sub_key_foo").unwrap();
assert_eq!("E86VGQhfxb_9rxSfjnBqKg", ekey);
assert_eq!(5, dkey);
}
*Note Point
We can use this crate with diesel also, just derive Encrypt, Decrypt both trait and define sub_key.
But make sure struct should contain a field id: u64
.
