[STANDALONE] OpenSSL has been compiled without RC2 support

[mwelsch]

Bug description

I want to use the standalone versions, and ran python3 fulfill.py ./mybook.acsm

After installing all the required packages I get this error, related to wbond/oscrypto#60 Any way around this?

That issue has been fixed in oscrypto's Git repo back in 2022 when that issue was closed.

However, wbond, the developer of oscrypto, hasn't released a new version of oscrypto since then, despite multiple people asking for a new one.

For the standalone scripts you'll probably have to uninstall the oscrypto version from your distribution / from pip, and manually install the latest version from their git repo.
