Is it possible to use kernel cryptographic functions in the userspace? Let's say, I don't have
md5sum binary installed on my system, but my kernel has
md5sum support. Can I use the kernel function from userspace? How would I do it?
Another scenario would be, if I don't trust the
md5sum binary on my system (my system could have been compromised), but I trust my kernel (I am using cryptographically signed kernel modules).
