ca-certs
« on: December 26, 2016, 09:50:14 AM »
For some reason git/curl refused to work without a ca-bundle.crt today.   I downloaded the latest and put it in /usr/local/etc/pki/certs/ca-bundle.crt  And everything was happy.

I can understand you not wanting to maintain cert extensions, but Is there an official way of obtaining certs for the various applications in piCore?

Also, openssl doesn't have any certs either, I've struggled getting any ca-certs openssl to work.

ca-certificates.tcz added to repo and as a dependency to openssl.tcz which is updated. Tested with curl, wget and git.

gnu wget works, anyway too fix busybox wget from the openssl side of things?   Right now busybox wget is not secure as it doesn't care if the cert validates.

busybox wget opens opensll with the following command line
Code: [Select]
1209 tc       wget https://github.com/Logitech/slimserver.git
 1210 tc       [openssl]
 1211 tc       openssl s_client -quiet -connect github.com:443

When openssl is opened with the above command line, it still cannot find the local certificate, but doesn't care.
Code: [Select]
tc@devel:~$ openssl s_client  -connect github.com:443
CONNECTED(00000003)

openssl now can verify certs without any special commands.   Unfortunately busybox wget still doesn't care if the cert validates.  This is probably a busybox source problem to fix.  They need to add -verify_return_error to their connect string, and then do something with it.  Unless there is a way to make openssl exit on cert validation error.

I was just looking at the busybox 1.26 change log.  While it appears that they are working on openssl compatability, they are moving to a different helper binary.
