Default Useflags for wget and curl: openssl versus gnutls?

A recent buglet in the wget package made me aware that openssl competes
with gnutls in certain ways. Even nss and libssh2 may be competing in
the same space, if maybe to a smaller extent.

Anyone here really understand the tradeoffs involved in the use of these
useflags, and why I might want to choose one over the other? Actually ATM
I have all four of those useflags enabled and I really don't understand
the potential consequences of my choices, which makes me worry just a bit.

Any clues much appreciated.

It all comes down to the relative quality of the packages involved,
there's no straight answer. Oftentimes one package has modern features
you need and want but is less stable|more buggy than the old package.

It's damn annoying because there's no firm recommendations, you had to
dig deep into the code to answer the question "what's best for ME?"

At least the ebuilds usually pick one out of the two if both USE flags
are defined and usually tell you in an elog.

Apologies for the reply which is a no-answer, it's the best I can do :-)

Months later, in another mailing list, I finally found a very practical
reason for picking one over the other: lawyers

The openssl project started under the aegis of the OpenBSD project, and
thus their license is solidly in the BSD camp.

The very name gnutls gives us a big hint about which license that project
favors

Apparently the nss license is at least not in bloody conflict with the
GPL, though I've not read the fine print and don't intend to. Well,
not until I've downed this delicious egg nog, anyway

Hi!

I noticed a few weeks ago that Gwibber, the GNOME social networking
app was not loading the timelines. After some troubleshooting it all
came to some security certificate problem in the curl library.
Switching from OpenSSL to gnutls solved the issue.

Greetings,

i on the other hand just had a situation where i was forced to recompile curl to link with openssl.

linking with gnutls caused connecting to a particular IIS web service to throw this "-9 unexpected length" error. [1] found no medicine other than to stick with openssl.
