To add to what others have said here, I'll point you to the authors of TweetNaCl, which sort-of competes with Sodium: http://tweetnacl.cr.yp.to/papers.html http://tweetnacl.cr.yp.to/papers.html Little is said, other than that TweetNaCl is smaller and thus more easily auditable. No criticism. No pointing out failures. Considering the source, that's IMO a serious compliment. (For comparison, read what is said of OpenSSL...) So in short, Sodium is a great library. It was forked from NaCl (the most trustable there is) and has some good features added, like scrypt, BLAKE2 and ChaCha. I think NaCl, TweetNaCl, and Sodium are a great ecosystem, each with different strengths. All great libraries, and the only ones I'd recommend unless you're doing TLS.
