PHP和C#可共用的可逆加密算法详解，
在一些项目中要求在php中生成加密，然后在asp.net中接受过来的密码再解密，下面和大家分享一个PHP与asp.net C#可共用的可逆加密算法，感兴趣的可以参考参考。
php加密算法：
key = $key;
if( $iv == 0 ) {
$this->iv = $key; //默认以$key 作为 iv
} else {
$this->iv = $iv; //mcrypt_create_iv ( mcrypt_get_block_size (MCRYPT_DES, MCRYPT_MODE_CBC), MCRYPT_DEV_RANDOM );
}
}
function encrypt($str) {
//加密，返回大写十六进制字符串
$size = mcrypt_get_block_size ( MCRYPT_DES, MCRYPT_MODE_CBC );
$str = $this->pkcs5Pad ( $str, $size );
return strtoupper( bin2hex( mcrypt_cbc(MCRYPT_DES, $this->key, $str, MCRYPT_ENCRYPT, $this->iv ) ) );
}
function decrypt($str) {
//解密
$strBin = $this->hex2bin( strtolower( $str ) );
$str = mcrypt_cbc( MCRYPT_DES, $this->key, $strBin, MCRYPT_DECRYPT, $this->iv );
$str = $this->pkcs5Unpad( $str );
return $str;
}
function hex2bin($hexData) {
$binData = "";
for($i = 0; $i strlen ( $text ))
return false;
if (strspn ( $text, chr ( $pad ), strlen ( $text ) - $pad ) != $pad)
return false;
return substr ( $text, 0, - 1 * $pad );
}
}
?>
asp.net程序代码：
using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Security.Cryptography;
using System.Text;
namespace WindowsFormsApplication1
{
///
/// DES加密解密字符串
///
public class DesEncryption
{
///
/// DES加密字符串
///
/// 待加密的字符串
/// 加密密钥,要求为8位
/// 加密成功返回加密后的字符串，失败返回null
public static string EncryptDES(string encryptString, string encryptKey = "11001100")
{
try
{
byte[] rgbKey = ASCIIEncoding.ASCII.GetBytes(encryptKey.Substring(0, 8));
byte[] rgbIV = rgbKey;
byte[] inputByteArray = Encoding.UTF8.GetBytes(encryptString);
DESCryptoServiceProvider dCSP = new DESCryptoServiceProvider();
MemoryStream mStream = new MemoryStream();
CryptoStream cStream = new CryptoStream(mStream, dCSP.CreateEncryptor(rgbKey, rgbIV), CryptoStreamMode.Write);
cStream.Write(inputByteArray, 0, inputByteArray.Length);
cStream.FlushFinalBlock();
StringBuilder ret = new StringBuilder();
foreach (byte b in mStream.ToArray())
{
ret.AppendFormat("{0:X2}", b);
}
ret.ToString();
return ret.ToString();
}
catch
{
return null;
}
}
///
/// DES解密字符串
///
/// 待解密的字符串
/// 解密密钥,要求为8位,和加密密钥相同
/// 解密成功返回解密后的字符串，失败返回null
public static string DecryptDES(string decryptString, string decryptKey = "11001100")
{
try
{
byte[] rgbKey = ASCIIEncoding.ASCII.GetBytes(decryptKey);
byte[] rgbIV = rgbKey;
byte[] inputByteArray = new byte[decryptString.Length / 2];
for (int x = 0; x
以上就是PHP和C#可共用的可逆加密算法，希望对大家的学习有所帮助。
