What a dumb, dumb comment. "don't use Go", why not? "don't follow the link", why not? It's a great explanation tailored towards programmers.

OpenSSL is useless for learning the basis of crypto (and the post is not about crypto, but whatever) because you need to understand the algorithms and the math aspect of the problem before you can follow and understand any terse and abstract implementation, and OpenSSL is also bad because it sacrifices lisibility for performance.
