1.ACSII码加密
//ACSII码加密
private static string ACSIIPWd(string rpwd)
{
string Ret;
byte[] array = System.Text.Encoding.ASCII.GetBytes(rpwd);
byte[] byteArray = new byte[array.Length];
for (int i = 0; i < array.Length; i++)
{
int asciicode = (int)(array[i]);
asciicode = asciicode + 1;
byteArray[i] = (byte)asciicode;
}
System.Text.ASCIIEncoding asciiEncoding = new System.Text.ASCIIEncoding();
string strCharacter = asciiEncoding.GetString(byteArray);
Ret = strCharacter;
return Ret;
}2.MD5加密
//MD5加密
private static string MD5PWd(string rpwd)
{
string Ret;
MD5 md5 = new MD5CryptoServiceProvider();
byte[] palindata = Encoding.Default.GetBytes(rpwd);//将要加密的字符串转换为字节数组
byte[] encryptdata = md5.ComputeHash(palindata);//将字符串加密后也转换为字符数组
Ret = Convert.ToBase64String(encryptdata);
return Ret;
}3.RSA加密
//RSA加密
private static string RSAPWD1(string myKeyContainerName)
{
string ret = "";
CspParameters cp = new CspParameters();
cp.KeyContainerName = myKeyContainerName;
RSACryptoServiceProvider rsa = new RSACryptoServiceProvider(cp);
ret = rsa.ToXmlString(true);
Console.WriteLine("Key is : \n" + rsa.ToXmlString(true));
return ret;
}4.DES加密
//DES加密
private static string DESPWD(string ciphertext)
{
string desPWD = "";
byte[] buffer;
DESCryptoServiceProvider DesCSP = new DESCryptoServiceProvider();
MemoryStream ms = new MemoryStream();//先创建 一个内存流
CryptoStream cryStream = new CryptoStream(ms, DesCSP.CreateEncryptor(), CryptoStreamMode.Write);//将内存流连接到加密转换流
StreamWriter sw = new StreamWriter(cryStream);
sw.WriteLine(ciphertext);//将要加密的字符串写入加密转换流
sw.Close();
cryStream.Close();
buffer = ms.ToArray();//将加密后的流转换为字节数组
desPWD = Convert.ToBase64String(buffer);//将加密后的字节数组转换为字符串
return desPWD;
}到此这篇关于C#实现加密的文章就介绍到这了。希望对大家的学习有所帮助，也希望大家多多支持编程网。
