Dear Thorsten,
after spending some time working on patches for pkcs11-proxy, I've found
that the 'bukka' fork as useful and modern updates:
https://github.com/bukka/pkcs11-proxy/
I'd argue the source should be based on that fork.
As you can see from that projects issues and pull requests, I've
proposed some fixes there; same goes for the Salsa MRs:
https://salsa.debian.org/alteholz/pkcs11-proxy/-/merge_requests
Happy to help doing this rebase or integrating more (ideally reviewed)
patches!
Best,
OdyX
