aesdemo.php：
例子，
makeKey($key); $encode = "123456";// 被加密的字符串 $ct = $aes->encryptString($encode, $keys); echo "encode = ".$ct."
"; $cpt = $aes->decryptString($ct, $keys); echo "decode = ".$cpt; ?>
例子、AES加密类
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), ".. ");
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));例子、附一个可加密可解密类
