Sounds like a problem with the entropy source.  AIX 5.2 has /dev/random 
and /dev/urandom, but I have seen one report about an AIX upgrade 
leaving those with incorrect permissions, I suggest you check those 
first.  They should be:

$ ls -l /dev/*rand*
crw-r--r--   1 root  system   42,  0 Jul 01 2003  /dev/random
crw-r--r--   1 root  system   42,  1 Jul 01 2003  /dev/urandom

Failing that, does "openssl rand -base64 32" also hang?

     Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.
