Hi. These following code will show you the encryption and decryption of your data.

C#

public static string EncryptString(string strString)
{
Byte[] _bitEncrypt;
string EnCrypted;

_bitEncrypt = ASCIIEncoding.ASCII.GetBytes(strString);
EnCrypted = Convert.ToBase64String(_bitEncrypt);
return EnCrypted;
}
public static string DecryptString(string strString)
{
Byte[] _bitDecrypt;
string Decrypted;

_bitDecrypt = Convert.FromBase64String(strString);
Decrypted = ASCIIEncoding.ASCII.GetString(_bitDecrypt);
return Decrypted;
}

VB

Public Function EncryptQueryString(ByVal queryString As String) As String
Dim _bitEncrypt As Byte()
_bitEncrypt = ASCIIEncoding.ASCII.GetBytes(queryString)
Dim encryptedQueryString As String = Convert.ToBase64String(_bitEncrypt)
Return encryptedQueryString
End Function

Public Function DecryptQueryString(ByVal queryString As String) As String
Dim _bitDecrypt As Byte()
_bitDecrypt = Convert.FromBase64String(queryString)
Dim decryptedQueryString = ASCIIEncoding.ASCII.GetString(_bitDecrypt)
Return decryptedQueryString
End Function

I hope this one will help many.
