I know there is a way to do it, but I don't know how to do it: the default backend for LUKS is
libgcrypt and I want to test it with the
openssl cryptographic library.
I was told that there is a configuration file to edit but I didn't find it.
On most distros the option
--with-crypto_backend=openssl won't compile without installing
libssl-dev (signaled as dependence) AND
pkg-config (NOT signaled).
