Simple CPU MD5 hash cracker, with JtR-like rules
mc++ will generate passwords from the supplied charset.
Example:
mc++ -a md5 -mb -c 0-9a-z --length 1-15 hashfile.md5
mc++ will generate passwords from supplied masks.
Example:
mc++ -a md5 -mB -r masks.txt hashfile.md5
where masks.txt can i.e. contain
[a-z][0-9]
[a-z][a-z][0-9]
[a-z][a-z][a-z][0-9]
mc++ will fetch passwords from file(s) and apply rules to them.
Example:
mc++ -a md5 -md -d dictionary.txt -r rules.txt hashfile.md5
where dictionary.txt contains passwords (one per line), and rules.txt contains rules,
that should be familiar to those who have used John the Ripper password cracker:

mc++ will join words from first and second dictionary, then apply rules.
Example:
mc++ -a md5 -m2 --start start.txt --end end.txt -r rules.txt hashfile.md5
-o <FILE> - write cracked hashes to <FILE>
--word-filter <RULE> - apply <RULE> after generating passwords (bruteforce and extended bruteforce modes)
--hash-filter <FILTER> - load only hashes matching <FILTER>
--in-between <STRING> - string to insert between words (two-dictionary mode)
To build mc++, issue the following commands:
mkdir build
cd build
cmake ..
make
mc++ will segfault if length of the resulting password after applying all rules exceeds maximum length (96 characters)
