Integrity Domain

Namespace: Infocyph\\Epicrypt\\Integrity

Scope

• string hashing

• file hashing

• digest verification

• timing-safe comparison support

• content fingerprint support

String Hashing

use Infocyph\Epicrypt\Integrity\StringHasher;

$hasher = new StringHasher('sha256');
$digest = $hasher->hash('payload');
$isValid = $hasher->verify('payload', $digest);

HMAC

$digest = $hasher->hash('payload', ['key' => 'hmac-secret']);

Blake2b

$blake = new StringHasher('blake2b');
$digest = $blake->hash('payload', ['length' => 32]);

File Hashing

use Infocyph\Epicrypt\Integrity\FileHasher;

$fileHasher = new FileHasher('sha256');
$digest = $fileHasher->hash('/path/to/file.txt');
$isValid = $fileHasher->verify('/path/to/file.txt', $digest);
