Fellow programmers, teach me how to hash data in mql4 (I seem to know how to use base64)

Mischek:
Yeah, they're looking for younger people now.

MD5 ?

sergeev:
MD5 is needed ?

MD5 I think I found an example somewhere.

sha256

I haven't dealt with it so for the most part I don't even know what's needed - here's a code example on the sprp:

protected string Login= "Получить на странице доступа к API";
    protected string Password = ""Получить на странице доступа к API";
    protected string Culture ="ru-RU";

    var RequestBalance = new { Login = Login, Wmid = wmid, Culture = Culture, Signature = HashToBase64(String.Format("{0};{1};{2};{3}", Login, Password, Culture, wmid), null)};
    string Response = ITServiceJson.Balance(ForceJson(RequestBalance));

 static public byte[] Hash(string plainString, Encoding encoding)
    {
      if (plainString == null)
        throw new ArgumentNullException("plainString");

      if (encoding == null)
        encoding = Encoding.UTF8;

      return Hash(encoding.GetBytes(plainString));
    }

    static public byte[] Hash(byte[] bytes)
    {
      if (bytes == null)
        throw new ArgumentNullException("bytes");
      using (SHA256 algorithm = new SHA256Managed())
      {
        byte[] hashBytes = algorithm.ComputeHash(bytes);
        return hashBytes;
      }
    }

    public string HashToBase64(string plainString, Encoding encoding)
    {
      if (plainString == null) throw new ArgumentNullException("plainString");
      return Convert.ToBase64String(Hash(plainString, encoding));
    }

I've figured out how to send a post request, but I need to make a hash here Signature:

name	destination	note
Login	trader login	is given to the trader on the API access page and is used to sign requests to the online exchange.
Password	trader password	obtained by trader on the API access page and used to sign requests to the online-exchange
Wmid	Trader's Wmid	WM identifier of the trader, when working with the online-exchange
Culture	query language	Defines the message language. (ru-RU, en-EN)
Signature	request signature	generated from parameters: Login + ';' + Password + ';' + Culture + ';' +Wmid

MD5 ?

No not MD5 exactly

I, being naive, wanted a ready-made one.

ZS: maybe winds has some built-in libraries that do this encryption.

Sorry about the misspelling.

Write in Sharpe, Sanek, you don't have to think much there.

I'm already on my 4th exchange, I'm implementing the api :)

It's hard for me to change, that's why I'm still on mucl4
