PHP 클래스 lithium\storage\session\strategy\Encrypt

To use this class, you need to have the mcrypt extension enabled. Example configuration: {{{ Session::config(array('default' => array( 'adapter' => 'Cookie', 'strategies' => array('Encrypt' => array('secret' => 'foobar')) ))); }}} By default, this strategy uses the AES algorithm in the CBC mode. This means that an initialization vector has to be generated and transported with the payload data. This is done transparently, but you may want to keep this in mind (the ECB mode doesn't require an itialization vector but is not recommended to use as it's insecure). You can override this defaults by passing a different cipher and/or mode to the config like this: {{{ Session::config(array('default' => array( 'adapter' => 'Cookie', 'strategies' => array('Encrypt' => array( 'cipher' => MCRYPT_RIJNDAEL_128, 'mode' => MCRYPT_MODE_ECB, // Don't use ECB when you don't have to! 'secret' => 'foobar' )) ))); }}} Please keep in mind that it is generally not a good idea to store sensitive information in cookies (or generally on the client side) and this class is no exception to the rule. It allows you to store client side data in a more secure way, but 100% security can't be achieved.

protected _encrypt ( array $decrypted = [] ) : string
$decrypted array The cleartext data to be encrypted.
리턴 string A Base64 encoded and encrypted string.

_hashSecret() 보호된 메소드

This method figures out the appropriate key size for the chosen encryption algorithm and then hashes the given key accordingly. Note that if the key has already the needed length, it is considered to be hashed (secure) already and is therefore not hashed again. This lets you change the hashing method in your own code if you like. The default MCRYPT_RIJNDAEL_128 key should be 32 byte long sha256 is used as the hashing algorithm. If the key size is shorter than the one generated by sha256, the first n bytes will be used.
