Token system for PHP.

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.

• PHP >= 5.3

$token = coin('mycoin', 'kB&(T#)G#&(t79 bvrc g0b72uxb479g&T087');

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

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

$token = coin('mycoin', 'kB&(T#)G#&(t79 bvrc g0b72uxb479g&T087');
$coin = validate_coin($token, 'kB&(T#)G#&(t79 bvrc g0b72uxb479g&T087');

if (!$coin) {
    echo "Invalid Coin";
} else {
    // If valid the value of the coin is returned from coin_validate
    echo 'Value contained in the coin : ' . $coin;
}

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

if (!$valid_coin) {
    echo "Invalid coin";
} else {
    // If valid the value of the coin is returned from validate
    echo 'Value contained in the coin : ' .  $valid_coin;
}
