Recent projects using AES encryption, but in the Internet to find a lot of libraries are OC and Java encryption can not decrypt items, because our server is written in Java, so can not be used for iOS is a big trouble, Android is more leisurely to write in Java, so nothing. However, in the degree Niang body searched all over, or let me find this library, source remember not clear, before looking for a lot of many libraries. The following records the u

AES (Encryption Standard, Chinese: Advanced Encryption Standard), is a block encryption standards. AES is processed by dividing the raw data into multiple 4x4 byte matrices, with a pre-defined key that makes each byte in each byte matrix XOR, replaced, shifted, and linearly transformed to achieve the purpose of encryption. The key length can be 128,192 or 256 bits. Here is an example of using the Python M2c

Copy CodeThe code is as follows: Class Aesmcrypt {public $iv = null;public $key = null;Public $bit = 128;Private $cipher;Public function __construct ($bit, $key, $iv, $mode) {if (Empty ($bit) | | empty ($key) | | empty ($IV) | | empty ($mode))return NULL;$this->bit = $bit;$this->key = $key;$this->iv = $iv;$this->mode = $mode;Switch ($this->bit) {Case 192: $this->cipher = mcrypt_rijndael_192; BreakCase: $this->cipher = mcrypt_rijndael_256; BreakDefault: $this->cipher = mcrypt_rijndael_128;}Swit

AES EncryptionAlgorithm.Block Cipher's various working modes, including ECB, CBC, and counter. Cipher has many problems to consider when using it as disk encryption. The main reason is that the ECB mode does not work (obviously), and the CBC mode is not good (random access is not allowed). Therefore, IEEE has standardized A p1619 standard, IEEE Standard for cryptographic protection of data on block-oriented storage devices, see http://ieeexplore.ieee.
