I would be happy to make urllib3 verify SSL certs by default but I'm not familiar enough with the nuances of locating the CA's in a distro-agnostic manner. If anyone has experience or ideas in doing this, please let me know. Bonus points if it works on OSX. Thanks! - Andrey On Fri, Sep 7, 2012 at 7:41 AM, Jan Lieskovsky <jlieskov@...hat.com> wrote: > Steve, > > in relation to this one the following question has been > raised internally - it's OK to assign CVE identifier for > end user applications, proclaiming to perform SSL certificates > verification, but not doing that. > > But what about the libraries?
