This is a port of my other C# library [Partial Key Verification Library for Compact Framework](https://opensource.duma.sh/libraries/net/partial-key-verification) into a PHP package.

This library implements Partial Key Verification (PKV). PKV is a cryptographic technique that allows verification of a subset of a key without revealing the entire key, enhancing security and privacy in various applications.

Check full documentation here: [opensource.duma.sh/libraries/php/partial-key-verification](https://opensource.duma.sh/libraries/php/partial-key-verification)

Installation
------------

[](#installation)

You can install the package via composer:

```
composer require kduma/pkv
```

Usage
-----

[](#usage)

```
private static function validateKey(string $key): bool {
	$seed = \KDuma\PKV\PartialKeyValidator::getSerialNumberFromKey($key);
	$blacklist = [1518008798, 42];
	if (in_array($seed, $blacklist, true))
		return false;

	// Validation for key with index 1
	if (!\KDuma\PKV\PartialKeyValidator::validateKey(new \KDuma\PKV\Checksum\Adler16(), new \KDuma\PKV\Hash\OneAtATime(), $key, 1, 766109221))
		return false;

	// Validation for key with index 4
	if (!\KDuma\PKV\PartialKeyValidator::validateKey(new \KDuma\PKV\Checksum\Adler16(), new \KDuma\PKV\Hash\Fnv1a(), $key, 4, 4072442218))
		return false;

	return true;
}
```
