PHP解密支付宝小程序的加密数据、手机号的示例

1.小程序端代码示例

my.getPhoneNumber({ success: (res) => { let encryptedData = res.response; my.httpRequest({ url: '你的后端服务端', data: encryptedData, }); }, fail: (res) => { console.log(res); console.log('getPhoneNumber_fail'); }, });

2.PHP后端解密示例

public static function decryptData($encryptedData, $key = '开发设置-接口内容加密方式-查看-字符串') { $encrys = json_decode($encryptedData, true); $encryptedData = $encrys['response']; $str = base64_decode($encryptedData); $screct_key = base64_decode($key); //设置全0的IV $iv_size = mcrypt_get_iv_size(MCRYPT_RIJNDAEL_128, MCRYPT_MODE_CBC); $iv = str_repeat("\0", $iv_size); $decrypt_str = mcrypt_decrypt(MCRYPT_RIJNDAEL_128, $screct_key, $str, MCRYPT_MODE_CBC, $iv); $decrypt_str = self::stripPKSC7Padding($decrypt_str); return $decrypt_str; } public static function stripPKSC7Padding($source) { $char = substr($source, -1); $num = ord($char); if ($num == 62) return $source; $source = substr($source, 0, -$num); return $source; }

3.解密返回

{"code":"10000","msg":"Success","mobile":"185xxxxx111"}

解密函数

/** * 解密 * * return mix */ function decryptData(string $encrypted_data) { $key = env('EAS'); $aesKey=base64_decode($key); $iv = 0; $aesIV=base64_decode($iv); $aesCipher=base64_decode($encrypted_data); $result=openssl_decrypt( $aesCipher, "AES-128-CBC", $aesKey, 1, $aesIV); return $result; }

解密过程

echo decryptData('EaieI1W9gPK0zClNbA7P0T6svaSYq/1xejihTXNVSH0WyCjBIcP2xOwaAevaYgb4aeQ5NNRQaqbZgVvfJKfaLQ=='); // {"code":"10000","msg":"Success","mobile":"1342XXXXXXX"}
