You almost certainly don't need to use the 'simplessl.c' example - that
example is for when you want to use an SSL client certificate to authenticate
to the server. If your bank just gave you a user name and password, this is
not what you want.

I don't know what you're trying to do here... For a regular 'ssl' site, just
use 'https://' instead of 'http://' and then program (lib)curl as normal.

No. If you need a client certificate (unlikely), your bank would have told you
how to make one (with some 'signup' page or a windows program), or supplied
one to you (as a file or floppy disk).

Yes, if you know what you are trying to do. It's not much use to you.

A certificate (client or server) certifies the identity of the machine
(website, hostname), not each individual page (URL), so 'Yes'.

You can use the same libcurl handle for https:// and http:// urls. Curl will
work it out.

As noted, you should just stick to 'simple.c' or 'simplepost.c' as examples,
and just use 'https://' instead of 'http://'.

(You are on a linux platform, so you shouldn't need to worry about your
'curl-ca-bundle' file - it should be already installed in the right place and
should contain the correct information to recognise your bank server. Windows
users would probably have to do a little libcurl work to either properly
configure or turn off ssl security checks).
