Description Richard Z. 2015-02-24 14:22:46 UTC
curl 7.39.0 and later support --pinnedpubkey - if compiled to use OpenSSL library.

As far as I can see this is the only cli download utility which is capable of certificate pinning at all so it would be really good to have that functionality.

Comment 1 Richard Z. 2015-02-24 14:53:42 UTC
more details:

<<This is currently only implemented in the OpenSSL, GnuTLS and GSKit backends.
  Added in libcurl 7.39.0 >>

Comment 2 Kamil Dudka 2015-02-24 14:54:30 UTC
I am not sure whether NSS API is ready for this.  I can see it is already implemented in Firefox:

... but curl might be too low-level of a tool to gain anything from the Firefox implementation.

Comment 3 Richard Z. 2015-02-24 18:54:26 UTC
Are we stuck with NSS?

Comment 4 Kamil Dudka 2015-02-25 09:09:04 UTC
(In reply to Richard Z. from comment #3)
> Are we stuck with NSS?

libcurl was ported to NSS as part of the Fedora Crypto Consolidation project:

We have put a lot of effort to make it stable and feature-complete.  If there is a requirement for the public key pinning, it is a reason to write a patch, not a reason to switch the backend IMO.

But you are free to recompile libcurl against OpenSSL or GnuTLS on your own...
