Authority Information Access certificate extension (AIA) support #2793
note: This is a copy of an old feature request from the old bug tracker: https://sourceforge.net/p/curl/feature-requests/83/
Please consider adding support for Authority Information Access certificate extension (AIA).
AIA can provide various things like CRLs but more importantly information about intermediate CA certificates that can allow validation path to be fullfilled.
Example site that uses certificate with AIA extension:
If you try the same URL with firefox or google chrome then certificate will be validated fine. That's because these browsers look into AIA and fetch intermediate certificate found there:
curl could do similar thing to firefox/google-chrome and fetch that intermediate gsdomainvalsha2g2r1.crt cert thus allowing validation to pass.
/cc @arekm since he filed the original issue.
This is a tracker for bugs. not feature-requests. This issue will thus subsequently be closed. Good features to add could be added to the
I believe Firefox doesn't support AIA, but it caches intermediate certs which is a primary reason why some HTTPS sites work with Firefox and not curl. I believe Chrome supports it.
