关于.net和java des加密

在.net和java环境中对于des加密，有几点要协同的地方：

1. 密钥和密钥向量Key IV
2. 加密模式CipherMode
3. 填充模式PaddingMode
4. 密文编码方式

下面一段.net的des加密方式

public string GetConsoleUrl(string vmName)
{
    string rs = string.Empty;
    using (CloudContext db = new CloudContext())
    {
        var configs = new ConfigurationRepository(db).GetAll().Where(x => x.Key.Equals("ConsoleUrl") || x.Key.Equals("ConsoleKey"));
        if (configs != null)
        {
            string url = string.Empty;
            string key = string.Empty;

            if (configs.FirstOrDefault(x => x.Key.Equals("ConsoleUrl")) != null)
                url = configs.First(x => x.Key.Equals("ConsoleUrl")).Value;
            if (configs.FirstOrDefault(x => x.Key.Equals("ConsoleKey")) != null)
                key = configs.First(x => x.Key.Equals("ConsoleKey")).Value;

            if (!string.IsNullOrEmpty(url) && !string.IsNullOrEmpty(key))
            {
                byte[] rgbKey = Encoding.UTF8.GetBytes(key);
                byte[] inputByteArray = Encoding.UTF8.GetBytes(vmName + "|" + DateTime.Now.ToString("yyyyMMddhhmmssfff"));
                byte[] rgbIV = rgbKey;

                DESCryptoServiceProvider des = new DESCryptoServiceProvider();
                des.Mode = CipherMode.ECB;
                MemoryStream ms = new MemoryStream();
                CryptoStream cs = new CryptoStream(ms, des.CreateEncryptor(rgbKey, rgbIV), CryptoStreamMode.Write);
                cs.Write(inputByteArray, 0, inputByteArray.Length);
                cs.FlushFinalBlock();

                StringBuilder sb = new StringBuilder();
                foreach (byte b in ms.ToArray())
                {
                    sb.AppendFormat("{0:X2}", b);   
                }
                rs = string.Format("http://{0}?token={1}", url, sb.ToString());
                ms.Close();
                ms.Dispose();

                return rs;
            }
        }
    }
    return rs;
}
