"combina" is a password generator that uses three different algorithms based on combinatorial analysis. It implements the Permutation without repetition, Permutation with repetition (the famous brute force), Combination without repetition and Combination with repetition. It supports unlimited number of characters in the input and MD5, SHA1 password hashes.

The libraries argtable2 and openssl are necessary for the compilation:

$ make

Example

$ combina --help
combina: A password generator that implements the combinatorial analysis. Usage: combina [-cmdraAns] [-k <int>] [-p <int>] [--user=STRING]... [--add-before=STRING]... [--add-after=STRING]... [--md5] [--sha1] [--help] [--version]

  -c                   Combination without repetition
  -m                   Combination with repetition
  -d                   Permutation without repetition
  -r                   Permutation with repetition (default)
  -k <int>             define the length of the passwords (default is 3)
  -p <int>             progressive length of the passwords (from p to k)
  -a                   add charset [abcdefghijklmnopqrstuvwxyz]
  -A                   add charset [ABCDEFGHIJKLMNOPQRSTUVWXYZ]
  -n                   add charset [0123456789]
  -s                   add charset [! "#$%&'()*+,-./:;<=>?@[\]^_`{|}~]
  --user=STRING        add your charset

--add-before=STRING add your const string before charset --add-after=STRING add your const string after charset

  --md5                return the MD5 hash
  --sha1               return the SHA1 hash
  --help               print this help and exit
  --version            print version information and exit
