软件功能：可用来加密任何文本，只要别人不知道你的密码，基本上他是暴力破解不了的，所以呀，机器上那些想保密的东西都用来加密吧，嘎嘎

AES高级加密标准 密码学中的高级加密标准，是美国联邦政府采用的一种区块加密标准。
主要代码：
using System;
using System.Text;
using System.Security.Cryptography;
using System.IO;
namespace YongFa365.Security
{
///
/// AES加密解密
///
public class AES
{
public static string Encrypt(string strEncrypt, string strKey)
{
try
{
byte[] keyArray = UTF8Encoding.UTF8.GetBytes(System.Web.Security.FormsAuthentication.HashPasswordForStoringInConfigFile(strKey, "md5"));
byte[] strEncryptArray = UTF8Encoding.UTF8.GetBytes(strEncrypt);
byte[] resultArray = null;
using (RijndaelManaged rDel = new RijndaelManaged())
{
rDel.Key = keyArray;
rDel.Mode = CipherMode.ECB;
rDel.Padding = PaddingMode.PKCS7;
ICryptoTransform cTransform = rDel.CreateEncryptor();
resultArray = cTransform.TransformFinalBlock(strEncryptArray, 0, strEncryptArray.Length);
}
return Convert.ToBase64String(resultArray, 0, resultArray.Length);
}
catch
{
return null;
}
}
public static string Decrypt(string strDecrypt, string strKey)
{
try
{
byte[] keyArray = UTF8Encoding.UTF8.GetBytes(System.Web.Security.FormsAuthentication.HashPasswordForStoringInConfigFile(strKey, "md5"));
byte[] strDecryptArray = Convert.FromBase64String(strDecrypt);

using (RijndaelManaged rDel = new RijndaelManaged())

}
return UTF8Encoding.UTF8.GetString(resultArray);
}
