這篇文章主要介紹了php實現的aes加密類，代碼中有使用方法,需要的朋友可以參考下
代碼如下: <?php 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:$this->cipher = MCRYPT_RIJNDAEL_192; break; case 256:$this->cipher = MCRYPT_RIJNDAEL_256; break; default: $this->cipher = MCRYPT_RIJNDAEL_128; } switch($this->mode) { case 'ecb':$this->mode = MCRYPT_MODE_ECB; break; case 'cfb':$this->mode = MCRYPT_MODE_CFB; break; case 'ofb':$this->mode = MCRYPT_MODE_OFB; break; case 'nofb':$this->mode = MCRYPT_MODE_NOFB; break; default: $this->mode = MCRYPT_MODE_CBC; } } public function encrypt($data) { $data = base64_encode(mcrypt_encrypt( $this->cipher, $this->key, $data, $this->mode, $this->iv)); return $data; } public function decrypt($data) { $data = mcrypt_decrypt( $this->cipher, $this->key, base64_decode($data), $this->mode, $this->iv); $data = rtrim(rtrim($data), "x00..x1F"); return $data; } } //使用方法 $aes = new AESMcrypt($bit = 128, $key = 'abcdef1234567890', $iv = '0987654321fedcba', $mode = 'cbc'); $c = $aes->encrypt('haowei.me'); var_dump($aes->decrypt($c));
