// Decode the salt and digest from a Bcrypt hash

// Using Base2n...

// Using native functions...

$rawSalt = base64_decode(strtr($encodedSalt, $bcrypt64alphabet, $base64alphabet)); // 16 bytes
$rawDigest = base64_decode(strtr($encodedDigest, $bcrypt64alphabet, $base64alphabet)); // 23 bytes
// Hexadecimal with Base2n...
$hexadecimal = new Base2n(4);
$encoded = $hexadecimal->encode('encode this'); // 656e636f64652074686973
$decoded = $hexadecimal->decode($encoded); // encode this
// It's better to use native functions...
$encoded = bin2hex('encode this'); // 656e636f64652074686973
$decoded = pack('H*', $encoded); // encode this
// As of PHP 5.4 you can use hex2bin() instead of pack()
