For what it's worth, I've used Botan in a personal project where I needed a few hashing algorithms to verify file integrity (SHA-1, SHA-256, even MD5), and also used Botan's base 64 decoder in the same project.

I found its modern "style" pleasant to write code for, and easy to integrate with good docs. That said, I did notice the large number of algorithms as others have pointed out, and I'm not sure I'd use it for more serious purposes when libsodium is well-established. It certainly wouldn't be an obvious choice.

But to quickly add support for common hash algorithms in a small project, I thought it was a good option and enjoyed its API design and simplicity.
