                       try {
                           for (byte b : md.digest(buffer.toString().getBytes("UTF-8"))) {
                               result.append(Integer.toHexString((b & 0xf0) >>> 4));
                               result.append(Integer.toHexString(b & 0x0f));
                           }
                       }

Answer 1

public static string EncryptPassword(string PasswordString, string PasswordFormat)
    {
        string EncryptPassword = null;
        if ("SHA1".Equals(PasswordFormat))
        {
            EncryptPassword = FormsAuthentication.HashPasswordForStoringInConfigFile(PasswordString, "SHA1");
        }
        else if ("MD5".Equals(PasswordFormat))
        {
            EncryptPassword = FormsAuthentication.HashPasswordForStoringInConfigFile(PasswordString, "MD5");
        }
        else
        {
            EncryptPassword = PasswordString;
        }
        return EncryptPassword.ToLower();
    }
