This class is a transparent base class for Encrypt and should not be accessed directly.
Kohana Encrypt provides a common interface to a variety of cryptography engines, supports multiple instances of cryptography engines through a grouped singleton pattern.
Class declared in SYSPATH/classes/Kohana/Encrypt.php on line 14.

string(7) "default"array $instancesEncrypt class instances.
array(0) Decrypts an encoded string back to its original value.

required - Encoded string to be decrypted. false - If decryption fails.stringabstract public function decode($data);Encrypts a string and returns an encrypted string that can be decoded.
$data = $encrypt->encode($data);
The encrypted binary data is encoded using base64 to convert it to a string. This string can be stored in a database, displayed, and passed using most other means without corruption.
