This was inspired by a simple program i wrote. How this happend.

1. Need something fun to do, tv is out.
2. Generate and write every posible password from a 72 charecter set
------"How big could it be any way? its just text!" i think to myself
3. Run aplication, walk away, come back its done (didn't time it :( )
4. Double click the new textfile on my desktop...work crashes on opening WTF?
5. Right click properties on file.... 10.8GB...... okkkayyy.
6. Find progam that can open file, amazingly there is.
7. Begin opening file, it has now been opening for 2 minutes, it reads 825 MILLION lines (and i wrote one password to each line) and it is still going up.
8. Stare at the numbers as they go up, for if i try to scroll the document while it is being opend, it will crash on me.
9. cry a little inside.

You could have calculated the possibilities easily with Combinatorics.

http://en.wikipedia.org/wiki/Combinatorial_analysis

Since passwords are unique and the order of characters matters but each character can be used more than once in each combination, the equation is very simple. Lets say your passwords were 7 characters long, with a choice of 72 characters:

72^7=10,030,613,004,288 possibilities.

If not all the passwords are the same length you would just add the possibilities for each lengths:

72^1+72^2+72^3+72^4=27,252,360 possibilities.

So ya... next time do a little math to prevent your hard drive from crashing and burning :twisted: lol

72^72 = possibilities, when you use 72 symbols with 72 positions ;) = 53449019547361999534025300140057538544940601393106611570269540644280818850419033099696863861289188541180498511377339362341642322313216

I knew that, and i had done it before hand, but i didn't think the text file would be so HUGE.
