Hi Ben, all,

So after all this what's the recommended way to use HMAC-SHA512 in Pharo 6?

Start poking around here...

https://github.com/Traadh/bittrex/blob/master/src/Bittrex.package/BittrexLibsodium.class/class/crypto_auth_hmacsha512__out.in.inlen.k..st

https://github.com/Traadh/bittrex/blob/master/src/Bittrex.package/BittrexPrivateAPI.class/instance/signRequest.st

Libsodium installation instructions...

I'd need it in combination with PBKDF2 to replicate this Python call:
PBKDF2(password, salt, iterations, macmodule=hmac,
digestmodule=hashlib.sha512).read(64)

I guess with iterations=1 you should get the same result as libsodium

I had to play around a bit before I worked out where to use bytes and where to use hex strings.

It might help to run these test cases through PBKDF2...��
