以下是关于对称加密算法的C#数据加密实现代码,大家可以根据需要更改不同的算法,文中以Rijndael算法为例:
- using System;
- using System.IO;
- using System.Security.Cryptography;
- using System.Text;
- namespace DataCrypto
- {
- ///
- /// C#数据加密对称加密算法类
- ///
- public class SymmetricMethod
- {
- private SymmetricAlgorithm mobjCryptoService;
- private string Key;
- ///
- /// 对称加密类的C#数据加密
- ///
- public SymmetricMethod()
- {
- mobjCryptoService = new RijndaelManaged();
- Key = "Guz(%&hj7x89H$yuBI0456FtmaT5&fvHUFCy76*h%(HilJ$lhj!y6&(*jkP87jH7";
- }
- ///
- /// 获得密钥
- ///
- ///
密钥 - private byte[] GetLegalKey()
- {
- string sTemp = Key;
- mobjCryptoService.GenerateKey();
- byte[] bytTemp = mobjCryptoService.Key;
- int KeyLength = bytTemp.Length;
- if (sTemp.Length > KeyLength)
- sTemp = sTemp.Substring(0, KeyLength);
- else if (sTemp.Length < KeyLength)
- sTemp = sTemp.PadRight(KeyLength, ' ');
- return ASCIIEncoding.ASCII.GetBytes(sTemp);
- }
- ///
- /// 获得初始向量IV
- ///
- ///
初试向量IV - private byte[] GetLegalIV()
- {
- string sTemp = "E4ghj*Ghg7!rNIfb&95GUY86GfghUb#er57HBh(u%g6HJ($jhWk7&!hg4ui%$hjk";
- mobjCryptoService.GenerateIV();
- byte[] bytTemp = mobjCryptoService.IV;
- int IVLength = bytTemp.Length;
- if (sTemp.Length > IVLength)
- sTemp = sTemp.Substring(0, IVLength);
- else if (sTemp.Length < IVLength)
- sTemp = sTemp.PadRight(IVLength, ' ');
- return ASCIIEncoding.ASCII.GetBytes(sTemp);
- }
- ///
- /// 加密方法
- ///
- /// 待加密的串
- ///
经过加密的串 - public string Encrypto(string Source)
- {
- byte[] bytIn = UTF8Encoding.UTF8.GetBytes(Source);
- MemoryStream ms = new MemoryStream();
