RSA签名加密及验证

PHP RSA+MD5签名demo：

 1 <?php
 2 ini_set('error_reporting', -1);
 3 ini_set('display_errors', -1);
 4 
 5 header('Content-Type: text/html; charset=utf-8');
 6 
 7 
 8 # openssl genrsa -out rsa_private_key.pem 1024
 9 # openssl rsa -in rsa_private_key.pem -pubout -out rsa_public_key.pem
10 
11 
12 $private_key = file_get_contents("rsa_private_key.pem");
13 $public_key = file_get_contents("rsa_public_key.pem");
14 
15 $data = 'test_abc';
16 
17 $res = openssl_get_privatekey($private_key);
18 openssl_sign($data, $sign, $res, OPENSSL_ALGO_MD5);
19 openssl_free_key($res);
20 $encrypt = base64_encode($sign);
21 echo $encrypt,"

PS：PHP 加密方法openssl_sign API：http://php.net/manual/zh/function.openssl-sign.php

Signature Algorithms 参数可以直接指定 OPENSSL_ALGO_MD5
