PHP使用AES进行加解密

前言

对接一个第三方平台，其使用AES对称加密

代码

//方式1
//加密
function enAES($originTxt, $key='Q6Mr6rDpn12iZb'){
    return base64_encode(openssl_encrypt($originTxt, 'AES-128-ECB',$key, OPENSSL_RAW_DATA));
}

//解密
function deAES($originTxt, $key='Q6Mr6rDpn2iOaZl')
{

    $data = base64_decode($originTxt);
    return openssl_decrypt($data, 'AES-128-ECB', $key, OPENSSL_RAW_DATA);
}



//方式2
class AESTest {
	private function unpad($text) {
		return substr($text, 0, strlen($text) - ord(substr($text, -1)));
	}

	public function decrypt($data, $key, $iv) {
		$key = substr(base64_encode($key), 0, 16);
		$data = base64_decode($data);
		$iv = substr($iv, 0, 16);
		$decrypted = openssl_decrypt($data, 'AES-128-CBC', $key, OPENSSL_RAW_DATA | OPENSSL_ZERO_PADDING, $iv);
		$data = $this->unpad($decrypted);
		return $data;
	}
}

$iv = 'A-16-Byte-String';
$key = 'd109090d17c54cedb2df6a251ce86d0baukidkidaukidaukid';
$content = 'p2ZdYGnw4ebE0YGIaMaoEGT4uVUhAXRFX/QqGUy7qZALE+8i9FY/Haeo/yU0umz56VQBGNGPg5k0WuUh7Et4Rb5R70MxrEBggtyHO1k/Svf1kZRzMWQCgaiDriFJQ/iXr7sZbQOCSMTgIa+CvxRjGYkF5mGniz/OtMLLfUXltZ9/toZ9mSa0kLmW2/e59FuUdB6HYX0t06bz+IcHmNAmCw7sy10AH0Eu5J626GY2rZsYyas9x33HxvMsqc9CkOkl8eYMwGb5s9BQnTNDd3FZQf6LPiYadz5aOrbM6r3hHpq5yEv2/u37PRDGFa7ZHNBTKTTUL0rBFZMk4yWEzHqfFv1vT2F5Of6DNoTkBvc+PHAksXI236ZRzgqbQwRQxAvw9qb87pocU3gPLf0dmFGcy/VWcOKxbkUuudKieyu4I=';
