There are research papers that describe how many bits you need to add
to your keys to remain strong over time taking into consideration
Moore's Law, computational advancements, CYBERCOMM/NSA collusions
(colliding?)etc. Here's a good one with many respected names on it:

I use 256 character base64 and 40 character hexadecimal encoded SHA1
sums generated from sentences for my passwords. IMO, these are good
for the foreseeable future. 64^280 is a darn big number as is 16^40.

Here's the program (SHA1_Pass) that generates my passwords:

Feel free to use it. Or abuse it freely. Pass on sha pass? ;)
