- Updated cppzmq headers to latest version from GitHub - Migrated all setsockopt() calls to new set() API with zmq::sockopt - Updated 19 occurrences across 2 files: * src/arqnet/sn_network.cpp (18 occurrences) * src/rpc/zmq_server.cpp (1 occurrence) - Maintained backward compatibility with ZMQ_IDENTITY for older ZeroMQ versions - All ZeroMQ/cppzmq warnings eliminated (37 -> 0) - Added compatibility verification documentation - Build successful with 0 warnings
…pzmq - Deleted `WERYFIKACJA_KOMPATYBILNOSCI_ZMQ.md` and `PODSUMOWANIE_OSTRZEZEN.md` files as they are no longer needed. - These documents contained outdated information regarding ZeroMQ compatibility and compilation warnings.
- Added compatibility for OpenSSL 3.0+ by introducing modern API calls for EC key generation and RSA key assignment. - Included necessary headers for EC support and updated existing structures to manage EC keys. - Ensured backward compatibility with OpenSSL 1.1.1 by providing fallback implementations. - Improved error handling and logging for key generation processes.
- Deleted the OpenSSL migration report as it is no longer needed. - Cleaned up `net_ssl.cpp` by removing unused includes and unnecessary conditional compilation for deprecated EC key management. - Streamlined RSA key assignment logic to focus on the current OpenSSL version without legacy checks. - Improved code clarity and maintainability by eliminating outdated structures and comments.
