  # custom charset - all hex values
  cracken -c 0123456789abcdef '?1?1?1?1'

  # 4 custom charsets - the order determines the id of the charset
  cracken -c 01 -c ab -c de -c ef '?1?2?3?4'

  # 4 lowercase chars with years 2000-2019 suffix
  cracken -c 01 '?l?l?l?l20?1?d'

  # starts with firstname from wordlist    with lastname from wordlist ending with symbol
  cracken -w firstnames.txt -w lastnames.txt -c '!@#$' '?w1?w2?1'

  # repeating wordlists multiple times and combining charsets
  cracken -w verbs.txt -w nouns.txt '?w1?w2?w1?w2?w2?d?d?d'


  ## Create Smartlists Subcommand Examples:

  # create smartlist from single file into smart.txt
  cracken create -f rockyou.txt --smartlist smart.txt

  # create smartlist from multiple files with multiple tokenization algorithms
  cracken create -t bpe -t unigram -t wordpiece -f rockyou.txt -f passwords.txt -f wikipedia.txt --smartlist smart.txt

  # create smartlist with minimum subword length of 3 and max numbers-only subwords of size 6
  cracken create -f rockyou.txt --min-word-len 3 --numbers-max-size 6 --smartlist smart.txt


  ## Entropy Subcommand Examples:

  # estimating entropy of a password
  cracken entropy --smartlist vocab.txt 'helloworld123!'

  # estimating entropy of a passwords file with a charset mask entropy (default is hybrid)
  cracken entropy --smartlist vocab.txt -t charset -p passwords.txt

  # estimating the entropy of a passwords file
  cracken entropy --smartlist vocab.txt -p passwords.txt

$ cracken entropy --help
cracken-entropy 

Computes the estimated entropy of password or password file.
The entropy of a password is the log2(len(keyspace)) of the password.

There are two types of keyspace size estimations:
  * mask - keyspace of each char (digit=10, lowercase=26...).
  * hybrid - finding minimal split into subwords and charsets.

FLAGS:
    -h, --help       Prints help information
    -s, --summary    output summary of entropy for password
    -V, --version    Prints version information

OPTIONS:
    -t, --mask-type <mask_type>              type of mask to output, one of: charsets(charsets only), hybrid(charsets+wordlists) [possible values: hybrid, charset]

       -f, --smartlist <smartlist>...           smartlist input file to estimate entropy with, a newline separated text file
