Alice and Bob can generate them by themselves, no

be random and can be re-generated with the same values

They cannot be simultaneously "random" and be capable of being
"re-generated with the same values".

At best, they are psudeo-random.  And, looking over the code, indeed,
they are generated from a psudeo-random generator, go's 'rand'.

Not the best choice in acronym, as 'nfs' is already quite well known in
tech circles as "Network File System".
