Crate cryptolens_yc

Cryptolens Rust Client

This crate provides helper function for managing and verifying license keys using cryptolens. It handles key activations, validations, and provides utilities for working with RSA keys for digital signatures.

Examples

Basic usage:

use cryptolens_yc::{key_activate, KeyActivateArguments};
// this is the example in original documentation
let public_key = "<RSAKeyValue><Modulus>khbyu3/vAEBHi339fTuo2nUaQgSTBj0jvpt5xnLTTF35FLkGI+5Z3wiKfnvQiCLf+5s4r8JB/Uic/i6/iNjPMILlFeE0N6XZ+2pkgwRkfMOcx6eoewypTPUoPpzuAINJxJRpHym3V6ZJZ1UfYvzRcQBD/lBeAYrvhpCwukQMkGushKsOS6U+d+2C9ZNeP+U+uwuv/xu8YBCBAgGb8YdNojcGzM4SbCtwvJ0fuOfmCWZvUoiumfE4x7rAhp1pa9OEbUe0a5HL+1v7+JLBgkNZ7Z2biiHaM6za7GjHCXU8rojatEQER+MpgDuQV3ZPx8RKRdiJgPnz9ApBHFYDHLDzDw==</Modulus><Exponent>AQAB</Exponent></RSAKeyValue>";

let product_id = "3646";
let key = "MPDWY-PQAOW-FKSCH-SGAAU";
let token = "WyI0NjUiLCJBWTBGTlQwZm9WV0FyVnZzMEV1Mm9LOHJmRDZ1SjF0Vk52WTU0VzB2Il0=";

let license_key = key_activate(
    token,
    KeyActivateArguments {
        ProductId: product_id.parse().unwrap(),
        Key: key.to_string(),
        MachineCode: "289jf2afs3".to_string(),
        ..Default::default()
    },
).unwrap();

match license_key.has_valid_signature(public_key) {
    Ok(valid) => assert_eq!(valid, true),
    Err(e) => panic!("Error: {}", e),
}

Offline Validation Example

 // get the license key from above code ...

 // save the license key to a file
 let path = "cached_license_key";
 save_license_key_to_file(&license_key, path)?;

 // you can also load the license key from a file
 let loaded_license_key = cryptolens_yc::load_license_key_from_file(path)?;

 // validate the loaded license key
 match loaded_license_key.has_valid_signature(public_key) {
     Ok(valid) => assert_eq!(valid, true),
     Err(e) => panic!("Error: {}", e),
 }
