It is harmless to use --no-random-seed-file. If you use it, GnuPG
will just get randomness from whatever your random source is. The
only difference is that it won't have a seed to start from, so it will
run a little slower.

Encryption shouldn't block. Key generation might (key generation
tries to use higher quality randomness). The random data used with
--no-random-seed-file is just as good as the random data otherwise: it
just takes longer to get to it.
