Re: [boost] A base64 library?

I'm interested in this, whether or not there is general interest for Boost, as it is an area of API research that could yield general benefits. With respect to base64 though, I would imagine we want it to at least be comparable in performance to this:

Looks like a great library - and pretty optimized. I've been looking into their source code and it looks like they dynamically query CPU capabilities and store them in a global struct without any protection - I'd say this makes the library not thread-safe. Looks like a good library to take inspiration from, especially regarding performance. Thanks, Ruben.
