PHP和C#可共用的可逆加密算法详解

这篇文章主要介绍了PHP和C#可共用的可逆加密算法，需要的朋友可以参考下

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。
