SHA256, SHA384 and SHA512 + HMAC - MetaTrader 4 Library

Many developers require these capabilities when working with different types of external APIs, such as Bitcoin and altcoin exchanges, which often require sending data via HMAC-SHA512, HMAC-SHA384, and HMAC-SHA256 and confirming parameter validity.

The MQL5 version of the SHA512 library can be found here: https://www.mql5.com/en/code/18158 . In addition to SHA512, SHA256 and SHA384 support have been added as separate libraries.

The HMAC function is transplanted from https://en.wikipedia.org/wiki/Hash-based_message_authentication_code

Usage example (tested at http://www.freeformatter.com/hmac-generator.html )
