求大神给个DES算法的PHP版，谢谢！

[mykelly6]

最近要写个接口，接口文档只有c#和java的加密方法，我这边开发环境是PHP的，百度了好多PHP版的算法，加密的提交过去都不对。。

public static string DESEnCode(string pToEncrypt,string sKey)
  {
            DESCryptoServiceProvider des = new DESCryptoServiceProvider();
            byte[] inputByteArray = Encoding.GetEncoding("UTF-8").GetBytes(pToEncrypt);


            des.Key = ASCIIEncoding.ASCII.GetBytes(sKey);
            des.IV = ASCIIEncoding.ASCII.GetBytes(sKey);
            MemoryStream ms = new MemoryStream();
            CryptoStream cs = new CryptoStream(ms, des.CreateEncryptor(), CryptoStreamMode.Write);

            cs.Write(inputByteArray, 0, inputByteArray.Length);
            cs.FlushFinalBlock();

            StringBuilder ret = new StringBuilder();
            foreach (byte b in ms.ToArray())
            {
                ret.AppendFormat("{0:X2}", b);
            }
            ret.ToString();
            return ret.ToString();
    }

public static String DESEncrypt(String key,String message){
		String encrypt = "";
		try {
			Cipher cipher = Cipher.getInstance("DES/CBC/PKCS5Padding");
			DESKeySpec desKeySpec = new DESKeySpec(key.getBytes("UTF-8"));
			SecretKeyFactory keyFactory = SecretKeyFactory.getInstance("DES");
			SecretKey secretKey = keyFactory.generateSecret(desKeySpec);
			IvParameterSpec iv = new IvParameterSpec(key.getBytes("UTF-8"));
			cipher.init(Cipher.ENCRYPT_MODE, secretKey, iv);
			byte[] b = cipher.doFinal(message.getBytes("UTF-8"));
			StringBuffer hexString = new StringBuffer();
			for (int i = 0; i < b.length; i++) {
				String plainText = Integer.toHexString(0xff & b[i]);
				if (plainText.length() < 2)
					plainText = "0" + plainText;
				hexString.append(plainText);
			}
			encrypt = hexString.toString();
			encrypt = encrypt.toUpperCase();
		} catch (Exception e) {
			e.printStackTrace();
		}
		return encrypt;
	}

百度到的算法是这样的，但是最后用16进制编码和base64编码都不行

    public function encryptDesEcbPKCS5($input, $key)
    {
        $size = mcrypt_get_block_size('des', 'ecb');
        $input = $this->pkcs5_pad($input, $size);
        $td = mcrypt_module_open('des', '', 'ecb', '');
        //获取密钥的最大长度
        $ks = mcrypt_enc_get_key_size($td);
        $key = substr($key, 0, $ks);
        //加密向量值
        $iv = mcrypt_create_iv (mcrypt_enc_get_iv_size($td), MCRYPT_RAND);
        //$iv =0;
        $tmp = mcrypt_generic_init($td, $key, $iv);
        $data = mcrypt_generic ($td, $input);
		
        mcrypt_generic_deinit($td);
        mcrypt_module_close($td);
        return strtoupper(bin2hex($data));
    }

解决了，用openssl的方法加密，可以兼容。

	//DES加密算法，兼容C#/JAVA
	private function encryPwd($encryString, $encryKey)
    {
        $keyLen   = strlen($encryKey);
        if (null == $encryKey || $keyLen < 8) {
            $encryKey = str_pad($encryKey, 8, '0', STR_PAD_RIGHT);
        }
        if ($keyLen > 8) {
            $encryKey = substr($encryKey, 0, 8);
        }
        $key     = mb_convert_encoding($encryKey, 'UTF-8');
        $message = mb_convert_encoding($encryString, 'UTF-8');
        $encry   = openssl_encrypt($message, 'DES-CBC', $key, OPENSSL_RAW_DATA, $key);

        return bin2hex($encry);
    }
