[Python-Dev] New OpenSSL - has anyone ever looked at (in)compatibility with LibreSSL

[Jim Baker]

I have no vested interest in this, other than the continuing work we have
done to make Jython compatible with OpenSSL's model, warts and all.

But the fact that BoringSSL cleans up the OpenSSL API (
https://boringssl.googlesource.com/boringssl/+/HEAD/PORTING.md), at the
cost of possible backwards breaking API changes looks reasonable. I suppose
there is some risk - perhaps the maintainers will decide that returning 1
should mean OK, but that's not going to happen, is it. The real issue here
is that no direct exposure of BoringSSL to other packages. I don't think
that happens with CPython. (Ironically it happens with Jython, due to how
signed jars poorly interact with shading/Java namespace remapping.)

Maintaining security means dealing with the inevitable churn. Did I mention
Jython's support of Python-compatible SSL? I think I did :p
