There are many options for packet capture: netlink, BPF classic, and of course eBPF. Within eBPF, the options for packet introspection are TC (Traffic Control) programs, XDP (eXpress Data Path) programs, and cgroup socket programs. We started with XDP but ran into …

This is because the code then becomes transparent to the algorithm used and much more flexible. EVP_DigestVerify() is a one shot operation which verifies a single block of data in one function.
