                        OUTPUT_DIR [--header-file HEADER_FILE]

Create hash cracking challenges

optional arguments:
  -h, --help            show this help message and exit
  --namelist NAMELIST   file containing challenge names, one per line
  --number NUMBER       number of challenges to create
  --challenge-file CHALLENGE_FILE
                        File containing a list of challenges to add
  --output-dir OUTPUT_DIR
                        Directory where output files will go
  --header-file HEADER_FILE
                        File containing a header to go before the table of
                        challenges

    The challenge file will have one challenge per line in the following format
    
        points mask algorithm description [url] [min_word][max_word]

    type is either h or w.  h is a hashcat mask, w is words from a file
    points - the number of points the challenge is worth
    hashcat_mask - a mask in hashcat format if the type is h. hashcat masks use built-in charsets (adds '?9' for alphanumeric and removes ?b)
    num_words - the number of words from the given file if the type is w
    algorithm - one of md5, sha1, or sha256
    description - a description of the challenge
    url - URL of the file from which the words will be obtained with one word per line  This argument is required if the type is 'w'
    min_word - the first line in the range from which to choose the words
    max_word - the last line in the range from which to choose the words
