RE: Generating session keys in RPG using HASH values

There is the C language runtime function srand and rand that will do
what you want, or you can call the OS/400 APIs that do the same thing
(can't remember their names off the top of my head). But basically you
start out with some "known" value and seed the random number routine
(srand or the API). Then you call the random number generator (rand or
the API) and it will create a random number for you. You then use that
random number to retrieve the next random number, and so on.

How about getting the current system time out to the millisecond?  
It isn't random, but it will be unique.

I need to generate a pseudo-random character string to be used as a
session key in my browser applications.  Has anyone used a hashing
method in RPG to generate a pseudo-random number and if so, could you
please post it. _______________________________________________
