加密要求 - SimplePlay

所有的网页查询服务在传送之前都要求用DES加密和MD5 Hashing进行数字签名，需确保内容在传输过程中不被修改。

请咨询我们如下信息：

Secret Key 密钥
EncrypKey 加密键
MD5Key MD5 键

ASP.Net C# DES加密函数例子：

protected byte[] EncryptKey = ASCIIEncoding.ASCII.GetBytes("ask_us_for_key");

public string DESEncrypt( string inString)
{
    MemoryStream ms = new MemoryStream();
    CryptoStream cs = new CryptoStream (ms, new DESCryptoServiceProvider ().CreateEncryptor(EncryptKey, EncryptKey), 
        CryptoStreamMode .Write);
    StreamWriter sw = new StreamWriter (cs);
    sw.Write(inString);
    sw.Flush();
    cs.FlushFinalBlock();
    sw.Flush();
    return Convert.ToBase64String(ms.GetBuffer(), 0, ( int )ms.Length);
}

protected byte[] EncryptKey = ASCIIEncoding.ASCII.GetBytes("ask_us_for_key");

public string DESEncrypt( string inString)

{

MemoryStream ms = new MemoryStream();

CryptoStream cs = new CryptoStream (ms, new DESCryptoServiceProvider ().CreateEncryptor(EncryptKey, EncryptKey),

CryptoStreamMode .Write);

StreamWriter sw = new StreamWriter (cs);

sw.Write(inString);

sw.Flush();

cs.FlushFinalBlock();

sw.Flush();

return Convert.ToBase64String(ms.GetBuffer(), 0, ( int )ms.Length);

}

PHP DES 加密函数例子：

<?php
class DES
{
    var $key;
    var $iv;
    function DES( $key, $iv=0 ) {
        $this->key = $key;
        if( $iv == 0 ) {
            $this->iv = $key;
        } else {
            $this->iv = $iv;
        }
    }

    function encrypt($str) {
        return base64_encode( openssl_encrypt($str, 'DES-CBC', $this->key, OPENSSL_RAW_DATA, $this->iv  ) );
    }

}
?>

<?php

class DES

{

var $key;

var $iv;

function DES( $key, $iv=0 ) {

$this->key = $key;

if( $iv == 0 ) {

$this->iv = $key;

} else {

$this->iv = $iv;

}

function encrypt($str) {

return base64_encode( openssl_encrypt($str, 'DES-CBC', $this->key, OPENSSL_RAW_DATA, $this->iv ) );

}

PHP 应用例子:

<?php
$str = "method=GetUserStatus&Key=01234567789ABCDEF0123456789ABCDE&Time=20150101012345&Username=abcd12345"; // for example
$key = 'ZyXw4321'; // for example
$crypt = new DES($key);
$mstr = $crypt->encrypt($str);
$urlemstr = urlencode($mstr);
echo "[ $str ] Encrypted: [ $mstr ] UrlEncoded encrypted string: [ $urlemstr ]";
?>

<?php

$str = "method=GetUserStatus&Key=01234567789ABCDEF0123456789ABCDE&Time=20150101012345&Username=abcd12345"; // for example

$key = 'ZyXw4321'; // for example

$crypt = new DES($key);

$mstr = $crypt->encrypt($str);

$urlemstr = urlencode($mstr);

echo "[ $str ] Encrypted: [ $mstr ] UrlEncoded encrypted string: [ $urlemstr ]";

ASP.Net C# MD5函数例子：

public string BuildMD5(string inString)
{
       byte[] hashed = MD5.Create().ComputeHash(Encoding.UTF8.GetBytes(inString));
       StringBuilder sb = new StringBuilder(hashed.Length * 2);
       for (int i = 0; i < hashed.Length; i++)
       {
            sb.Append(hashed[i].ToString("x2"));
       }
       return sb.ToString();
}

public string BuildMD5(string inString)

{

byte[] hashed = MD5.Create().ComputeHash(Encoding.UTF8.GetBytes(inString));

StringBuilder sb = new StringBuilder(hashed.Length * 2);

for (int i = 0; i < hashed.Length; i++)

{

sb.Append(hashed[i].ToString("x2"));

}

return sb.ToString();

}

PHP 应用例子:

<?php
$str="method=GetUserStatus&Key=01234567789ABCDEF0123456789ABCDE&Time=20150101012345&Username=abcd12345"; // for example
$md5key = "abcdefg"; // for example
$Time = "20150101012345"; // for example
$SecretKey = "01234567789ABCDEF0123456789ABCDE"; // for example
$PreMD5Str = $str . $md5key . $Time . $SecretKey;
$OutMD5 = md5($PreMD5Str);
echo "md5:[ $OutMD5 ]";
?>

<?php

$str="method=GetUserStatus&Key=01234567789ABCDEF0123456789ABCDE&Time=20150101012345&Username=abcd12345"; // for example

$md5key = "abcdefg"; // for example

$Time = "20150101012345"; // for example

$SecretKey = "01234567789ABCDEF0123456789ABCDE"; // for example

$PreMD5Str = $str . $md5key . $Time . $SecretKey;

$OutMD5 = md5($PreMD5Str);

echo "md5:[ $OutMD5 ]";
