How to Encode and Decode Password in Asp.net Registration and Login Page using C#?

Answer 1

You can ecrypt the password as given below:

   private string Encrypt_Password(string password)
    {
        string pwdstring = string.Empty;
        byte[] pwd_encode = new byte[password.Length];
        pwd_encode = Encoding.UTF8.GetBytes(password);
        pwdstring = Convert.ToBase64String(pwd_encode);
        return pwdstring;
    }  

Decode Password:

 private string Decrypt_Password(string encryptpassword)
    {
        string pwdstring = string.Empty;
        UTF8Encoding encode_pwd = new UTF8Encoding();
        Decoder Decode = encode_pwd.GetDecoder();
        byte[] todecode_byte = Convert.FromBase64String(encryptpassword);
        int charCount = Decode.GetCharCount(todecode_byte, 0, todecode_byte.Length);
        char[] decoded_char = new char[charCount];
        Decode.GetChars(todecode_byte, 0, todecode_byte.Length, decoded_char, 0);
        pwdstring = new String(decoded_char);
        return pwdstring;
    }
