private string iv = "23456789 ";
private string key = "34567890 ";

加密是这样的
public string EncryptString(string str)**************
{
byte[] ivb = Encoding.ASCII.GetBytes(this.iv);
byte[] keyb = Encoding.ASCII.GetBytes(this.EncryptKey);//加密密钥
byte[] toEncrypt = this.EncodingMode.GetBytes(str);//加密的内容
byte[] encrypted;
ICryptoTransform encryptor = des.CreateEncryptor(keyb, ivb);
MemoryStream msEncrypt = new MemoryStream();
CryptoStream csEncrypt = new CryptoStream(msEncrypt, encryptor, CryptoStreamMode.Write);
csEncrypt.Write(toEncrypt, 0, toEncrypt.Length);
csEncrypt.FlushFinalBlock();
encrypted = msEncrypt.ToArray();
csEncrypt.Close();
msEncrypt.Close();
//return encrypted;***************************************
return this.EncodingMode.GetString(encrypted);
}
解密是
public string DecryptString(string str)**********************
{
byte[] ivb = Encoding.ASCII.GetBytes(this.iv);
byte[] keyb = Encoding.ASCII.GetBytes(this.EncryptKey);
byte[] toDecrypt = this.EncodingMode.GetBytes(str);**********
byte[] deCrypted = new byte[toDecrypt.Length];
ICryptoTransform deCryptor = des.CreateDecryptor(keyb, ivb);
MemoryStream msDecrypt = new MemoryStream(toDecrypt);
CryptoStream csDecrypt = new CryptoStream(msDecrypt, deCryptor, CryptoStreamMode.Read);
