这是我的加密和解密方法.我有两个数据库,我将加密的密码从一个数据库复制到另一个数据库.代码是在vb中,但我将其转换为C#.

 using System;
 using System.Collections.Generic;
 using System.Linq;
 using System.Text;
 using System.Security.Cryptography;
 using System.IO;
 namespace AccountSystem.Class{
class ClEncrDecr
{
    private TripleDESCryptoServiceProvider tripleDESCryptoServiceProvider = new TripleDESCryptoServiceProvider();

    private byte[] TruncateHash(string key, int length)
    {
        SHA1CryptoServiceProvider sha1 = new SHA1CryptoServiceProvider();
        //Hash the Key
        byte[] keyBytes = System.Text.Encoding.Unicode.GetBytes(key);
        byte[] hash = sha1.ComputeHash(keyBytes);

        // truncate or pad the hash
        Array.Resize(ref hash, length);
        return hash;
    }

    public ClEncrDecr()
    {
        string key = "ABCD";
        tripleDESCryptoServiceProvider.Key = TruncateHash(key, tripleDESCryptoServiceProvider.KeySize / 8 );
        tripleDESCryptoServiceProvider.IV = TruncateHash("", tripleDESCryptoServiceProvider.BlockSize / 8 ); …
