Well, I've been running a script for the past couple of days that creates the combinations of a specified word of length with the chars abcdefghijklmnopqrstuvwxyz1234567890 for those of you know what this is, I won't bother explaining it unless it is asked. It is currently on it's 6th revolution, and nearing 1billion combinations! I'll keep you posted on what it is, and here is a picture of its current status.

LOL, didn't I warn you that recursion can impart exponential overhead??

... ok maybe I didn't, but still, if you're going to store the results in a plain text file, it's going to end up being approx 14.2 GB in size. Confused

I wonder if you used SetBatchLines -1 in your code.... because Razz if you didn't.

For a standard 12 character length password there is in total 37^12=6.58e18 different combinations which requires an excess of 5.7 Exbibit (roughly 6 billion GB) of storage for a fixed-length null inclusive table. A project of this magnitude is ambitious, but it'll be interesting to see the effectiveness of your application (algorithms, performance, etc.).

VxE, the exact size of the folder that holds the files would be..16.218292236328125 GB (Being that each file is 13122 KB). I have however forgotten to add in the batch lines command which I think would have greatly helped me.

Oberon, you are almost there. It's actually 36**12 or 4,738,381,338,321,616,896. Also, I believe the average password to be about 8 in length (due to the inactivity of this generations brain.) Also, if each character is roughly 1 byte, and each password is on its own line, I think the size of the file(s) would be roughly..52,955,538,090.1875 GB only if my caculations are correct Wink Which I hope, and believe they aren't because the Rainbow Tables Are at a maximum of 50 GB.
