密码加密
DVBBS NET1.1版中的密码加密之后是这种效果.
是用MD5加密吗?好像不是,请问是用那种方式加密的.加解密如何操作.

------解决方案--------------------
///MD5加密
public string MD5Encrypt(string pToEncrypt, string sKey)
{
DESCryptoServiceProvider des = new DESCryptoServiceProvider();
byte[] inputByteArray = Encoding.Default.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();


}

///MD5解密
public string MD5Decrypt(string pToDecrypt, string sKey)
{ 
DESCryptoServiceProvider des = new DESCryptoServiceProvider();
 
byte[] inputByteArray = new byte[pToDecrypt.Length / 2];
for(int x = 0; x < pToDecrypt.Length / 2; x++)
{
int i = (Convert.ToInt32(pToDecrypt.Substring(x * 2, 2), 16));
inputByteArray[x] = (byte)i;
}
 
des.Key = ASCIIEncoding.ASCII.GetBytes(sKey);
des.IV = ASCIIEncoding.ASCII.GetBytes(sKey);
MemoryStream ms = new MemoryStream();
CryptoStream cs = new CryptoStream(ms, des.CreateDecryptor(),CryptoStreamMode.Write);
cs.Write(inputByteArray, 0, inputByteArray.Length);
cs.FlushFinalBlock();
 
StringBuilder ret = new StringBuilder();

return System.Text.Encoding.Default.GetString(ms.ToArray());
}

protected void Button1_Click(object sender, EventArgs e)
{
this.Label1.Text= MD5Encrypt(this.TextBox1.Text, "8lvbe4kE");

}
protected void Button2_Click(object sender, EventArgs e)
{
this.Label1.Text=MD5Decrypt(this.Label1.Text, "8lvbe4kE");
}
