Calculate Disk Space Size Needed To Generate A Wordlist For Password Cracking

Today I was having a discussion regarding wordlist size, the calculation to come up with the specific size the wordlist would be once generated, and various other items revolving around password cracking. Somehow the application crunch came up which in the past has been used to generate wordlists however its fairly slow compared to other technologies out there specifically Hashcat/oclHashcat’s Anyhow during the discussion I was doing some searching and had not used crunch in quite a long time but was pleasantly surprised by one of the features which generates a quick, accurate, and useful output of information regarding number of combinations that will be generated from the combinations length plus the character set/wordlists input and how much disk space those the list will take up on the hard drive. Anyhow a couple interesting things I realized tonight using crunch that I wanted to share.

Wordlist Menu Tool for Backtrack 4 Final

I get really sick of trying to remember all the commands I use to work with wordlists so I had some free time and decided to finally get it all in one place.  I started out just gathering all my notes in a text file but then I decided to code up a menu to make the commands easy to access. Normally I would keep something like this just for my own use since I doubt any one would want it but I decided to release it anyway.
