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'.

 
It uses now xorshift128+ instead of math.rand, to have a  128bit
seed instead of 64bit.

And it is still psudeo-random.

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

 
I know, but I keep the name unless there is a standard Linux or Windows
command with the same name.

That is your choice, just be prepared for lots of confusion on the part
of others.
