oqs-epiphany not working

[baentsch]

          Thanks, @jellejurre for the setup above. I'm absolutely baffled by what I see: The httpd server in your setup properly responds to queries fielded by an equivalent `oqsprovider` build/client, e.g.,

docker run --network epiphany_default -it openquantumsafe/curl sh -c "openssl s_client --connect epiphany-server-1:4433 -groups kyber768"

Also, the epiphany (browser) image in your composition properly operates openssl and oqsprovider when logging in to it via docker exec, e.g.

openssl list -providers -verbose
Providers:
  default
    name: OpenSSL Default Provider
    version: 3.3.0
    status: active
    build info: 3.3.0-dev
    gettable provider parameters:
      name: pointer to a UTF8 encoded string (arbitrary size)
      version: pointer to a UTF8 encoded string (arbitrary size)
      buildinfo: pointer to a UTF8 encoded string (arbitrary size)
      status: integer (arbitrary size)
  oqsprovider
    name: OpenSSL OQS Provider
    version: 0.5.4-dev
    status: active
    build info: OQS Provider v.0.5.4-dev (510fea6) based on liboqs v.0.10.0-dev
    gettable provider parameters:
      name: pointer to a UTF8 encoded string (arbitrary size)
      version: pointer to a UTF8 encoded string (arbitrary size)
      buildinfo: pointer to a UTF8 encoded string (arbitrary size)
      status: integer (arbitrary size)
openssl s_client -connect test.openquantumsafe.org:6036 -groups kyber768

"Just" when putting the two things together, i.e., using the known-good local openssl code against the known-good oqs-httpd, things fail:

openssl s_client -connect epiphany-server-1:4433 -groups kyber768
Connecting to 172.18.0.3

oqs-epiphany then not working is a logical consequence. But the issue is somewhere else. Will need to debug into this...

Local build of oqs-epiphany is not correctly working. Neither is the latest (0.9.2) image at docker hub. This requires a serious review of the changes in the underlying code base, most likely glib-networking.

[isaleh-sb]

Came here to make this ticket, but see that it's already reported 👍 ...

Just as an extra data point, the only openquantumsafe/epiphany image that I'm able to get any successful handling of PQC certificates with is 0.7.2 (this is hitting sites with Dilithium & Falcon certs hosted by the latest openquantumsafe/nginx image). 0.8.0 and onwards all fail with any PQC certs for every algorithm:

SSL_do_handshake() failed (SSL: error:0A000076:SSL routines::no suitable signature algorithm) while SSL handshaking

[baentsch]

Yup - I'm painfully aware of this. When looking into this, I got stymied by a crash of the docker image on my machine and have not found the time to look into this more deeply. If you'd be able to do some "digging", I'd be really grateful, @isaleh-sb . In general, running the command openssl s_client .... successfully is the prerequisite to epiphany working OK: Can you confirm (or the opposite :) of this being the case in your setup?

I don't know much about build systems but I did figure out the following:

RUN cd /opt/liboqs && mkdir build && cd build && cmake -GNinja -DOQS_DIST_BUILD=ON -DCMAKE_INSTALL_PREFIX=/opt/liboqs .. && ninja && ninja install
RUN cd /opt/oqs-provider && cmake -GNinja -DOQS_DIST_BUILD=ON -Dliboqs_DIR=/opt/liboqs -S . -B _build && cd _build && ninja && ninja install
RUN cd /opt/openssl && ./config no-shared --prefix=/opt/oqssa -lm && make -j 2  && make install_sw install_ssldirs && sed -i "s/default = default_sect/default = default_sect\noqsprovider = oqsprovider_sect/g" /opt/oqssa/ssl/openssl.cnf && sed -i "s/\[default_sect\]/\[default_sect\]\nactivate = 1\n\[oqsprovider_sect\]\nactivate = 1\n/g" /opt/oqssa/ssl/openssl.cnf && sed -i "s/providers = provider_sect/providers = provider_sect\nssl_conf = ssl_sect\n\n\[ssl_sect\]\nsystem_default = system_default_sect\n\n\[system_default_sect\]\nGroups = \$ENV\:\:DEFAULT_GROUPS\n/g" /opt/oqssa/ssl/openssl.cnf && sed -i "s/\# Use this in order to automatically load providers/\# Set default KEM groups if not set via environment variable\nKDEFAULT_GROUPS = $DEFAULT_GROUPS\n\n# Use this in order to automatically load providers/g" /opt/oqssa/ssl/openssl.cnf && sed -i "s/HOME\t\t\t= ./HOME\t\t= .\nDEFAULT_GROUPS\t= ${DEFAULT_GROUPS}/g" /opt/oqssa/ssl/openssl.cnf

doesn't work, yet

RUN cd /opt/liboqs && mkdir build && cd build && cmake -G"Ninja" .. -DOQS_DIST_BUILD=ON -DCMAKE_INSTALL_PREFIX=/opt/oqssa && ninja install
RUN cd /opt/openssl &&LDFLAGS="-Wl,-rpath -Wl,/opt/oqssa/lib64" ./config shared --prefix=/opt/oqssa && make -j 4 && make install_sw install_ssldirs;
RUN cd /opt/oqs-provider && ln -s ../openssl . && cmake -DOPENSSL_ROOT_DIR=/opt/oqssa -DCMAKE_BUILD_TYPE=Release -DCMAKE_PREFIX_PATH=/opt/oqssa -S . -B _build && cmake --build _build  && cp _build/lib/oqsprovider.so /opt/oqssa/lib64/ossl-modules && sed -i "s/default = default_sect/default = default_sect\noqsprovider = oqsprovider_sect/g" /opt/oqssa/ssl/openssl.cnf && sed -i "s/\[default_sect\]/\[default_sect\]\nactivate = 1\n\[oqsprovider_sect\]\nactivate = 1\n/g" /opt/oqssa/ssl/openssl.cnf && sed -i "s/providers = provider_sect/providers = provider_sect\nssl_conf = ssl_sect\n\n\[ssl_sect\]\nsystem_default = system_default_sect\n\n\[system_default_sect\]\nGroups = \$ENV\:\:DEFAULT_GROUPS\n/g" /opt/oqssa/ssl/openssl.cnf && sed -i "s/\# Use this in order to automatically load providers/\# Set default KEM groups if not set via environment variable\nKDEFAULT_GROUPS = $DEFAULT_GROUPS\n\n# Use this in order to automatically load providers/g" /opt/oqssa/ssl/openssl.cnf && sed -i "s/HOME\t\t\t= ./HOME\t\t= .\nDEFAULT_GROUPS\t= ${DEFAULT_GROUPS}/g" /opt/oqssa/ssl/openssl.cnf

does.

I don't know enough about build configurations to know the difference, but maybe this is useful to you.

[jellejurre]

I've got it!

The openssl version that is installed before liboqs is installed needs to be 3.2 or higher. 3.1 or lower (the default ubuntu libssl-dev is 3.0.3 I believe) doesn't work.

To illustrate, this doesn't work:

yet the same script with branch openssl-3.2 does. In a similar vein, moving the openssl install after the oqs provider install breaks it as well, so this seems to imply it's the version of openssl that is used to install the oqs-provider that matters.

So by swapping my oqs install commands to the ones shown above (+ some other config), I managed to get my dockerfile to handle signatures correctly.

Maybe it would be smart to use the fullbuild script in the oqs-epiphany demo to circumvent this

[baentsch]

I've got it!

Thanks for letting us know!

Sounds like a good suggestion. Would you feel like contributing a PR to facilitate that?

[jellejurre]

I'd love to, but I can't actually run the default image so I can't test it ^^

The only linux machines I have are on VMs and those dont like the display streaming through docker that this uses

[jellejurre]

Oh and this change did manage to make openssl work on my branch, but epiphany still didnt do the signatures properly for some reason

Now I'm confused: Didn't you say before signatures work OK with 3.2:

The latter is (for openssl) entirely expected: See https://github.com/open-quantum-safe/oqs-provider?tab=readme-ov-file#note-on-openssl-versions (some provider-sig-enabling PRs didn't get backported to older OpenSSL versions).

[jellejurre]

yeah, so openssl did the signatures correctly, but epiphany did not.

This could be because my fix was bad, as I am not an expert on the networking epiphany uses.

I'll see if I can get a dockerfile that shows this.

[jellejurre]

yeah I think I might be putting the provider in the wrong place or something. This is my code where openssl works fine but the epiphany doesn't.

STOPSIGNAL SIGTERM

with this, docker run -it browsertest openssl s_client -connect test.openquantumsafe.org:6109 --groups kyber768 works but docker run -p 9876:9876 browsertest and going to test.openquantumsafe.org:6109 or test.openquantumsafe.org:6057 doesn't. Neither for kem not for signature, so if I had to guess I'm putting the oqs provider in the wrong places.

#298 will be marking epiphany as deprecated, but I believe we should leave this issue open to allow new contributors to potentially "un-deprecate" epiphany and update it to working order
