linkchecker TLS Support?

Hi there,

it seems that linkchecker (or the underlying ssl library) doesn't support TLS. I tried to check some links on a host who supports only TLS, but the linkcheck raises an error an aborts:

My linkchecker version is

INFO 2014-11-08 21:24:05,049 MainThread Checking intern URLs only; use --check-extern to check extern URLs.
LinkChecker 9.3 released 16.7.2014

It would be really great if you can support TLS.

I believe I bumped into this same issue. Below is the error message I get in linkchecker when accessing an https (TLS 1.0) site.

********** Oops, I did it again. *************

You have found an internal error in LinkChecker. Please write a bug report at https://github.com/wummel/linkchecker/issues and include the following information:

the URL or file you are testing

the system information below

When using the commandline client:

your commandline arguments and any custom configuration files.

the output of a debug run with option "-Dall"

Not disclosing some of the information above due to privacy reasons is ok. I will try to help you nonetheless, but you have to give me something I can work with ;) .

There should probably also be a command option to ignore ssl failures on certain urls, so that you can test against a local site without an SSL cert.
