Class

EncryptEncryptDecryptTest

Test basic encryption and decryption.

Code

function testNoneEncryptDecrypt() {

  // First, generate a random string to encrypt.
  $random = $this
    ->randomName(10);

  // Encrypt the string.
  $encrypted = encrypt($random, array(), 'none');
  $this
    ->assertNotEqual($random, $encrypted, t('None: A value, encrypted, does not equal itself.'));
  $this
    ->assertTrue(strpos($encrypted, 'a:') === 0, t('None: The encrypted value is a serialized array.'));

  // Since no actual encryption is being performed, ensure that the "encrypted" text is the same as the original.
  $encryptedArray = unserialize($encrypted);
  $this
    ->assertEqual($random, $encryptedArray['text'], t('None: Initial value equals "encrypted" value.'));

  // Then, decrypt the encrypted string.
  $decrypted = decrypt($encrypted, array(), 'none');
  $this
    ->assertEqual($random, $decrypted, t('None: A value, decrypted, equals itself.'));
