OpenSSL 1.1 test keys

Hi Jakub,

While working on the OpenSSL 1.1 integration, I've stumbled over this issue with the sni server test ext/openssl/tests/sni_server.phpt which fails with

error:1416F086:SSL routines:tls_process_server_certificate:certificate verify failed

I debugged through it and in the end it turns out, that likely the test CA might be not compatible with the latest OpenSSL, at least with the vanilla build with the default options. I use the default OpenSSL build with static engines, as usual. It excludes quite some weak functionality, so I guess we've no actual bug. Please also see the checks I made with the console tool

C:\php-sdk\php71\vc14\x64\php-src
$ openssl version
OpenSSL 1.0.2k 26 Jan 2017

C:\php-sdk\php71\vc14\x64\php-src
$ openssl.exe verify -CAfile ext\openssl\tests\sni_server_ca.pem ext\openssl\tests\sni_server_domain1.pem
ext\openssl\tests\sni_server_domain1.pem: OK

On master with OpenSSL 1.1 however, seems the CA is invalid

C:\php-sdk\phpmaster\vc15\x64\php-src
$ openssl version
OpenSSL 1.1.0e 16 Feb 2017

C:\php-sdk\phpmaster\vc15\x64\php-src
$ openssl verify -CAfile ext\openssl\tests\sni_server_ca.pem ext\openssl\tests\sni_server_domain1.pem
C = US, ST = SC, L = Myrtle Beach, O = php.tests subordinate, CN = php.tests.subordinate
error 24 at 1 depth lookup: invalid CA certificate
error ext\openssl\tests\sni_server_domain1.pem: verification failed

As mentioned, there's likely no bug, but I think it were not bad to double check this test. A fix to it could be to just produce another keys and CA with stronger dependency. I currently added a skip to the aforementioned test in master, mainly as I'm about to switch AppVeyor to newer deps and vc15 and the test were producing the fails all the time. Also not sure, which OpenSSL version Travis runs currently, but I had this test failing on Linux with the vanilla OpenSSL 1.1 build as well.

Thanks

Hi Anatol

Yep I have been looking a little bit and it really seems that it is about
the CA cert and OpenSSL 1.1 is a bit more strict about verification of it.
IIRC it was failing on extension part when I was quickly debugging it. When
I check purpose using

$ openssl x509 -in sni_server_ca.pem -purpose

then it is visible that the cert is not a server CA which should probably
be but not sure if that's the reason. I think we will need to use a
different cert for that test. I have got it on my todo list so hopefully
will add something more sensible that works soon unless you want to do it.
Until then skip is fine ;)

Cheers

Jakub

Thanks for the confirmation. Linking Daniel as well as the patch author. I'd prefer you guys to care about the new test data, probably the most reliable way to do it :)

Thanks
