From the article: Disables and removes dependency on OpenSSL. Many features, including SSH protocol 1 are not supported and the set of crypto options is greatly restricted. This will only work on systems with native arc4random or /dev/urandom. I haven't dug into the source code, but I'd wager that the crypto options that remain are Ed25519, ChaCha20-Poly1305, etc. (Don't quote me on this, however.)
