I have already been down that path, but not successfully. /dev/urandom is
not available on the platform - never has, never will to my knowledge. This
does appear to work if PRNGD is correctly running, but I can't seem to get
that to work on this site. The config.mak.uname for NonStop does specify:

CSPRNG_METHOD = openssl

which should use OPENSSL_random(), shouldn't it? OpenSSL 3.0 uses the
_rdrand() builtin so should ever go to PRNGD, but it seems like this is
anyway. Debugging isn't possible as this is not on my own systems - and
things work here. Is there any kind of tracing I can do?
