[PHP3] RE: [PHPLIB] Extending user_auth table or creating a new table From: Howard Ha (howardh <email protected>)

The 32byte long hash is good for security, but what does it matter whether
people know what your uid is? And though nobody has an intention of typing
the uid ever, can you imagine a forum system where your 32byte uid is stored
with the messages? Wouldn't a 300,000 message base with only 15,000 members
then take way more space using the hash as a join parameter? (i think that
works out to be around 9MB of hash storage compared to 1.7MB with regular
autoincrement) I just assumed the space savings and speed would be good.
