Tests for encrypt.module

Class

EncryptEncryptDecryptTest

Test basic encryption and decryption.

Code

function testMCryptEncryptDecrypt() {
  if (function_exists('mcrypt_encrypt')) {
    $random = $this
      ->randomName(10);
    $encrypted = encrypt($random, array(), 'mcrypt_rij_256');

    // Test that the original value does not equal the encrypted value (i.e. that the data is actually being encrypted).
    $this
      ->assertTrue(strpos($encrypted, 'a:') === 0, t('MCrypt: The encrypted value is a serialized array.'));
    $encryptedArray = unserialize($encrypted);
    $this
      ->assertNotEqual($random, $encryptedArray['text'], t('MCrypt: A value, encrypted, does not equal itself.'));
    $decrypted = decrypt($encrypted, array(), 'mcrypt_rij_256');
    $this
      ->assertEqual($random, $decrypted, t('MCrypt: A value, decrypted, equals itself.'));
  }
  else {
    debug('MCrypt extension not present. Skipping tests.');
  }
