GnuPG 1.4.23 for DOS (Announce)

posted by bencollver Homepage, 09.05.2024, 23:32

I think it worked for me because i was generating 1024 bit keys. When i tried to generate a 4096 bit keypair on MS-DOS, it failed, presumably because it was blocking on an empty entropy pool in the NOISE device.

I posted gpg14c.zip which honors the RNG_DEVICE environment variable. If you set RNG_DEVICE=/dev/urandom$ then GnuPG will use that when it generates keys. This will guarantee that it never blocks on an empty entropy pool, but i will reiterate that the documentation warns against doing this.

From a crypto standpoint it would probably be better to explore the other entropy sources, which involve tweaking and rebuilding NOISE. I will look into that and also look into building your Turbo Pascal source code when i find the time. Thanks for the source code.
