I.e. for userspace stuff? That is obviously the right usage, but Linux
cryptoapi does not have userspace interface, so was my question.
Actually I was several times already asked after acrypto was closed, how
userspace can use new hardware drivers, and frankly I do not know what
the best userspace API would look like (in one of the projects I already
used all three methods one-by-one and failed to determine the best).
Simple char device read/write or ioctl, or blocking/nonblocking syscall
over file descriptor, or anything else?
