[janani13]

Hai all, I'm encrypting the password by using the code as below . Please tell me how to decrypt the same.Please help me..

#region Password Util
/// <summary>
/// Encrypts a string using the SHA256 algorithm.
/// </summary>
public static string HashPassword(string plainMessage)
{
byte[] data = Encoding.UTF8.GetBytes(plainMessage);
using (HashAlgorithm sha = new SHA256Managed())
{
byte[] encryptedBytes = sha.TransformFinalBlock(data, 0, data.Length);
return Convert.ToBase64String(sha.Hash);
}

}

protected void btnSubmit\_Click(object sender, EventArgs e)
{
    bo.UserID = txtUserId.Text;
    Password p = new Password(txtPassword.Text.ToString());
    String newpwd = p.SaltedPassword;
    System.Nullable<int> newsaltkey = p.Salt;
    bo.Encryptpwd = newpwd;
    bo.Saltkey = p.Salt;
    bo.Password = txtPassword.Text;

    passwordFormat = MembershipPasswordFormat.Hashed;
    if (passwordFormat == MembershipPasswordFormat.Hashed)
        bo.Blogpwd = HashPassword(txtPassword.Text);
    else
        bo.Blogpwd = txtPassword.Text;

Hash Algorithm are one way encryption.You can not decrypt what you can do,you can encrypt the text and then match with the encrypted one.If you require to decrypt the data then you can use other algorithms...
