I haven't looked at GnuPG, but there is an entropy source available
for DOS. The "noise" program installs character devices RANDOM$ and
URANDOM$, which can be used like /dev/random and /dev/urandom. These
are already incorporated into the latest DOS port of the stable
version of openssl. Noise is not currently being developed, but
you can get the latest version from my web site. To use noise, you
would generally have to modify your source code to accept RANDOM$ or
/dev/random$ in addition to /dev/random. I am the current maintainer for
noise, even though I am not programmer. If anyone wants to continue
development on the program, please let me know.
