Curl perhaps yes, but it employs zlib and libssl to operate, right so?

[zvr]

Yes, it uses zlib and some implementation of SSL.

My earlier comment about "SSL" is that the actual library might be OpenSSL, BoringSSL, WolfSSL, GnuTLS, or any one of a number of others. So the number of uses of each one is smaller than the total number of "SSL" uses.
