We already know about DES algorithm
method
The RSA Public Key Encryption is useful method
for Encryption and Decryption .The Code behind the Method is mention below.
using
System;
using
System.Collections;
using
System.Collections.Generic;
using
System.Data;
using
System.Diagnostics;
using
System.Security;
using
System.Security.Cryptography;
using
System.Text;
using
System.IO;
public
class Tester
{
public static
void Main()
{
RSACryptoServiceProvider myRSAProvide =
new
RSACryptoServiceProvider();
string strCrypt = null;
byte[] bteCrypt = null;
byte[] bteResult = null;
try
{
strCrypt =
"12345678";
bteCrypt =
Encoding.ASCII.GetBytes(strCrypt);
bteResult =
myRSAProvide.Encrypt(bteCrypt, false);
Console.WriteLine(Encoding.ASCII.GetString(bteResult));
}
catch (CryptographicException
ex)
{
Console.WriteLine(ex.Message);
}
string strResault =
null;
byte[] bteDecrypt =
null;
try
{
bteDecrypt =
myRSAProvide.Decrypt(bteResult, false);
strResault =
Encoding.ASCII.GetString(bteDecrypt);
Console.WriteLine(strResault);
}
catch (CryptographicException
ex)
{
Console.WriteLine(ex.Message);
}
Console.ReadLine();
}
}
It is very simple pubic
key encryption and decryption method.
