I was in a similar situation  yesterday, I looked at the same ticket, and probably the same search results that took me there. I was close to including the beast detail implementation, like some SO post suggested. but in the end Vinnies comments about not doing that made me look further. 

Daniel Lemire has a post describing how to do fast base64 encoding/decoding https://lemire.me/blog/2018/01/17/ridiculously-fast-base64-encoding-and-decoding/ 
which is implemented in this library which is still maintained (last commit 3 weeks ago) https://github.com/aklomp/base64
to be honest, I've not yet made the tests to verify that it works, but it is for sure easy to work with, and supposedly very fast.

I am lazy and would have used the boost version if it existed something neat. but maybe there isn't a real need for it to be in boost.

Kind Regards
