django-signing-rust

该软件包实现了 Django 的字符串和对象加密签名功能，适用于 Rust。

use serde::{Deserialize, Serialize};
use django_signing;

const SECRET: &[u8] = b"my-secret-key";
const SALT: &[u8] = b"demo-salt";

#[derive(Debug, Serialize, Deserialize)]
struct Book {
    title: String,
    author: String,
    year: u16,
}

let book = Book {
    title: String::from("The Lord of the Rings"),
    author: String::from("J. R. R. Tolkien"),
    year: 1954,
};

let signed = django_signing::dumps(book, SECRET, SALT, true);

println!("Signed value: {}", signed);
// This prints something like:
// Signed value: eyJ0aXRsZSI6IlRoZSBMb3JkIG9mIHRoZSBSaW5ncyIsImF1dGhvciI6IkouIFIuIFIuIFRvbGtpZW4iLCJ5ZWFyIjoxOTU0fQ:1n5aMt:Q7rI7rBXrLmMFsxLPnkiLl1GCr_ygqsM0nHBkazgvYc

let unsigned: Book = django_signing::loads(
    signed, SECRET, SALT,
    // Signature expires after 60 seconds
    django_signing::Duration::new(60, 0)
).unwrap();

println!("Unsigned value: {:?}", unsigned);
// This prints:
// Unsigned value: Book { title: "The Lord of the Rings", author: "J. R. R. Tolkien", year: 1954 }

还可以访问与 Django 的 Signer 和 TimestampSigner 类相关的 BaseSigner 和 TimestampSigner 结构体。

由于 SHA-1 在当今通常不是一个好主意，因此该库仅支持 SHA-256。
