slrc - Simple [Slow?! *g] Linux Rar Cracker v0.2 (66 Downloads)

I wrote this to practise/test bash getopts and also because I didn't find any
rar cracker for linux when I wanted to check a file against a wordlist.
I know doing it this way is slow but I wanted a quick hack ;)

Features:
- wordlist checks
- brute-force checks (uses john as stdin)
- restore for brute-force
- statistical information during wordlist crack ([current try/tries left/total tries] [tries/s] [current runtime/expected total runtime])
- statistical information during brute-force ([current try] [tries/s])
- being slow ;)

testfile 1
testfile 2

Examples:


Wordlist mode using john's wordlist:

[sb@develbox ~/slrc]$ ./slrc -f test.rar -w ~/john/password.lst
