Possible use cases

• Creating an activation link for users
• Creating a password reset link

Basic Example:

use nobsign::Signer;
let signer = Signer::new(b"my secret");

// Let's say the user's ID is 101
let signed = signer.sign("101");

// You can now email this url to your users!
let url = format!("http://yoursite.com/activate/?key={}", signed);

// Later check the signature and get the value back
let unsigned = signer.unsign(&signed).unwrap();

Example with timestamped signatures

use nobsign::TimestampSigner;
let signer = TimestampSigner::new(b"my secret");

// Let's say the user's ID is 101
let signed = signer.sign("101");

// You can now email this url to your users!
let url = format!("http://yoursite.com/activate/?key={}", signed);

// In your code, you can verify the expiration:
signer.unsign(&signed, 86400).unwrap(); // 1 day expiration
