This should compile on most systems. Get ufc for greater speed. DOS
compile requires external crypt() function.

/* TinyCrack v1.0 by Bluesman@cyberspace.org 1/95 
   If your tired of having to use gigantic password crackers for a quick-fix, 
   then you might try using this program. It does the basics. It scans for 
   nulls, tries usernames and account names and of course it runs with any 
   wordlist dictionary. TO COMPILE: gcc -O2 tc.c -o tc
