推荐答案
请下次如果我们看到一半的问题，那么它将被视为垃圾邮件，并且不会给出任何答复，是的，您在写什么里面有完整的螃蟹，请使用下面的代码
为此创建一个单独的类
Please next time if we see half question then it will be consider spam and no response to it will be given , and yes what u writing in there is complete crab , user the below code
create a seprate class for it
using System.Collections.Generic;
using System;
using System.Security.Cryptography;
using System.Text;
using System.IO;
private static Byte[] sharedkey = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16 };
private static Byte[] sharedvector = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16 };
public static string Encrypt(string val)
{
TripleDESCryptoServiceProvider tdes = new TripleDESCryptoServiceProvider();
Byte[] toEncrypt = Encoding.UTF8.GetBytes(val);
MemoryStream ms = new MemoryStream();
CryptoStream cs = new CryptoStream(ms, tdes.CreateEncryptor(sharedkey, sharedvector), CryptoStreamMode.Write);
cs.Write(toEncrypt, 0, toEncrypt.Length);
cs.FlushFinalBlock();
return Convert.ToBase64String(ms.ToArray());
}
public static string Decrypt(string val)
{
TripleDESCryptoServiceProvider tdes = new TripleDESCryptoServiceProvider();
Byte[] toDecrypt = Convert.FromBase64String(val);
MemoryStream ms = new MemoryStream();
CryptoStream cs = new CryptoStream(ms, tdes.CreateDecryptor(sharedkey, sharedvector), CryptoStreamMode.Write);
cs.Write(toDecrypt, 0, toDecrypt.Length);
cs.FlushFinalBlock();
return Encoding.UTF8.GetString(ms.ToArray());
}
