{
    "require": {
        "blackcube/lockbot": "*"
    }
}

composer install
./vendor/bin/codecept build
./vendor/bin/codecept run

To check coverage report:

./vendor/bin/codecept run --coverage --coverage-html

Usage

Captcha class allows you to generate and verify POW CAPTCHA codes.

Generating CAPTCHA Codes

use blackcube\lockbot\Captcha;

$captcha = new Captcha();
$challenge = $captcha->generateChallenge(); // Generate a CAPTCHA challenge
// $challenge is an array with 'algorithm' and 'salt' and 'hash' keys
// ['algorithm' => 'sha256', 'salt' => 'random_salt', 'hash' => 'computed_hash']

Verifying CAPTCHA Codes

// $solution is the solution provided by the user ['salt' => 'challenge_salt', 'hash' => 'challenge_hash', 'algorithm' => 'challenge_algorithm', 'solution' => 'user_solution']
use blackcube\lockbot\Captcha;
$captcha = new Captcha(
    algorithm: $solution['algorithm'] // Use the same algorithm as the challenge);
);
$isValid = $captcha->verifySolution($solution['salt'], $solution['hash'], $solution['solution']); // Verify the provided solution

Main methods are:

• Generate a CAPTCHA challenge
• generateChallenge(): array
• Verify a provided solution
• verifySolution(string $salt, string $hash, string $solution): bool
