Hi,

I am not an expert at all in this area, but what I understand 
from the related RFCs for TOTP and HOTP is that you need HMAC 
SHA1. This functionality is already included in Phobos.
Therefore you do not need openssl or botan but "just" implement 
the algorithm as explained here

https://tools.ietf.org/html/rfc4226

Kind regards
