PHP7 版本后,官方舍弃 mcrypt_module 系列的方法了。
比如 mcrypt_module_open, mcrypt_module_open , mcrypt_generic_deinit ,mcrypt_generic 等。
改用 openssl_encrypt 和 openssl_decrypt 。
所以,在公众号的SKD中,修改 pkcs7Encoder.php文件中 pkcs7Encoder 类即可。
class Prpcrypt { public $key; /**向量 */ public static $IV = \"12asd67890123412\";//16位 public static $AES = \'AES-256-CBC\'; function __construct($k) { $this->key = base64_decode($k . \"=\"); } public function encrypt($text, $appid) { try { //获得16位随机字符串,填充到明文之前 $random = $this->getRandomStr(); $text = $random . pack(\"N\", strlen($text)) . $text . $appid; $pkc_encoder = new PKCS7Encoder; $text = $pkc_encoder->encode($text); $encrypted = openssl_encrypt($text,self::$AES,$this->key,OPENSSL_RAW_DATA,self::$IV); return array(ErrorCode::$OK, base64_encode($encrypted)); } catch (Exception $e) { //print $e; return array(ErrorCode::$EncryptAESError, null); } } public function decrypt($encrypted, $appid) { $decrypted = openssl_decrypt(base64_decode($encrypted),self::$AES,$this->key,OPENSSL_RAW_DATA,self::$IV); try { //去除补位字符 $pkc_encoder = new PKCS7Encoder; $result = $pkc_encoder->decode($decrypted); //去除16位随机字符串,网络字节序和AppId if (strlen($result) < 16) return \"\"; $content = substr($result, 16, strlen($result)); $len_list = unpack(\"N\", substr($content, 0, 4)); $xml_len = $len_list[1]; $xml_content = substr($content, 4, $xml_len); $from_appid = substr($content, $xml_len + 4); } catch (Exception $e) { //print $e; return array(ErrorCode::$IllegalBuffer, null); } if ($from_appid != $appid) return array(ErrorCode::$ValidateAppidError, null); return array(0, $xml_content); } function getRandomStr() { $str = \"\"; $str_pol = \"ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789abcdefghijklmnopqrstuvwxyz\"; $max = strlen($str_pol) - 1; for ($i = 0; $i < 16; $i++) { $str .= $str_pol[mt_rand(0, $max)]; } return $str; } }
