Need some help on how to correctly assign the RSA key

I generated the public and private key, added the public key in binance. But I keep getting errors like "Invalid character in header content ["X-MBX-APIKEY"]" "API-key format invalid"

I've tried to assign the value in environment variables and load them with "process.env". Tried removing newlines to convert key to a single line. Also tried to replace newline with text "\n". I've also assigned the keys directly in the code.

Maybe it's something very simple but iI can figure it out .

Hi @posman - does your private key by any chance have this as the header?

-----BEGIN RSA PRIVATE KEY-----

Or how does the header look? There's an assumption right now in how the RSA auth works, I'll adapt it slightly, as well as providing an example.

@posman here's a full example for RSA authentication using this SDK: https://github.com/tiagosiebler/binance/blob/master/examples/rest-private-rsa.md

If you have any problems with it, please open another issue. Thanks!
