Certain certificates aren't valid due to missing struct fields

[Wertzui123]

Firstly, sorry if this issue is written poorly - I just noticed the symptoms of this, but I don't (yet) understand TLS or the TLSe code base well enough to actually understand what's the problem here.

Anyway, so I've tried to reach github.com (or www.github.com, it doesn't matter) on port 443 using the tlsclienthello.c example. It doesn't work though. So I tried to investigate the issue, and it looks like there's a problem with the certificate validation.

tls_certificate_verify_signature returns 0 due to cert->sign_key etc. being zeroed; this seems like a bug to me.

tls_certificate_verify_signature is called by tls_certificate_chain_is_valid.

Am I doing anything wrong? Or is this a known issue already? Thank you!

This happens with TLS 1.2 as well as TLS 1.3.
