/** |
||||
* Pure-PHP implementation of AES. |
||||
* |
||||
* Uses mcrypt, if available/possible, and an internal implementation, otherwise. |
||||
* |
||||
* PHP versions 4 and 5 |
||||
* |
||||
* If {@link Crypt_AES::setKeyLength() setKeyLength()} isn't called, it'll be calculated from |
||||
* {@link Crypt_AES::setKey() setKey()}. ie. if the key is 128-bits, the key length will be 128-bits. If it's 136-bits |
||||
* it'll be null-padded to 192-bits and 192 bits will be the key length until {@link Crypt_AES::setKey() setKey()} |
||||
* is called, again, at which point, it'll be recalculated. |
||||
* |
||||
* Since Crypt_AES extends Crypt_Rijndael, some functions are available to be called that, in the context of AES, don't |
||||
* make a whole lot of sense. {@link Crypt_AES::setBlockLength() setBlockLength()}, for instance. Calling that function, |
||||
* however possible, won't do anything (AES has a fixed block length whereas Rijndael has a variable one). |
||||
* |
||||
* Here's a short example of how to use this library: |
||||
* <code> |
||||
* <?php |
||||
* include('Crypt/AES.php'); |
||||
* |
||||
* $aes = new Crypt_AES(); |
||||
* |
||||
* $aes->setKey('abcdefghijklmnop'); |
||||
* |
||||
* $size = 10 * 1024; |
||||
* $plaintext = ''; |
||||
* for ($i = 0; $i < $size; $i++) { |
||||
* $plaintext.= 'a'; |
||||
* } |
||||
* |
||||
* echo $aes->decrypt($aes->encrypt($plaintext)); |
||||
* ?> |

* Pure-PHP implementations of keyed-hash message authentication codes (HMACs) and various cryptographic hashing functions. |

* |

* Uses hash() or mhash() if available and an internal implementation, otherwise. Currently supports the following: |

* <code> |

* decryption round when the continuous buffer is enabled. When it's disabled, they remain constant. |

||||
* Put another way, when the continuous buffer is enabled, the state of the Crypt_DES() object changes after each |
||||
* encryption / decryption round, whereas otherwise, it'd remain constant. For this reason, it's recommended that |
||||
* continuous buffers not be used. They do offer better security and are, in fact, sometimes required (SSH uses them), |

* however, they are also less intuitive and more likely to cause you problems. |
