Token system in PHP

coin

Token system for PHP.

Introduction

Coin is a simple means of generating tokens that are flexible, secure and can contain an any arbitrary data which is stored within the token itself. A coin is generated using the SHA-1 hashing algorithm and an algorithm that randomly inserts the data within the hash for extraction.

Coin is to be used a means of adding a simple layer of security for applications, it should NOT be used as a method of securing sensitive information and I make no guarantees that this is 100% safe, the data is stored within the string so it is completely viewable by the world and this is not a method of encrypting or hashing!

Now that I've covered those basics here are some examples.

Generating a coin

$coin = new Coin();
$token = $coin->generate('mycoin', 'kB&(T#)G#&(t79 bvrc g0b72uxb479g&T087');

Generates a coin of

bd-36-6-d131b7277331bc917ab780e47cd2a56d3cmycoin6dbf

Take note if you use this example your results will vary as each coin is randomly generated.

Validating a coin

$coin = new Coin();
$validated = $coin->validate($token, 'kB&(T#)G#&(t79 bvrc g0b72uxb479g&T087')

if (!$validated) {
    echo "Invalid coin";
} else {
    echo $validated;
}

// Once validated the coin's value is returned
