Krüptel implements Web Crypto API and exposes a PHP interface for server side checking encryption and two interfaces for client side AES encryption: enkrüptionalize to optionally encrypt and dekrüptionalize to optionally decrypt the passed argument, if secret is stored or method is ask for secret.

Method Store secret Ask for secret Secret

PHP (optional server-side)

require 'cryptel.php';

Krüptel::isEncrypted(outputValue)

Javascript (client-side)

<script src="cryptel.php?js"></script>

Encrypt (Promise with optional callback)

enkrüptionalize(inputValue[, reject]).then(...)

Decrypt (Promise without any callback)

dekrüptionalize(outputValue).then(...)

Batch decryption (with optional callback)

dekrüptionalize(getElementById('foo')[, resolve])

dekrüptionalize(querySelectorAll('li')[, resolve])
