|-h, --help||Help. Print usage information and exit.|
|Print license info and exit.|
|Print version info and exit.|
|-K key, --key key|
|Specify the approximate key on the command line, rather than prompting the user for it.|
|-d n, --depth n|
|Search keys that contain up to n changes. The default is 5.|
|Keep trying more keys even after the first match is found. By default, ccguess will stop after the first key is found that matches all input files.|
|-t chars, --chartable chars|
|Specify the list of characters to try for replacements and insertions. By default, ccguess will try all printable ASCII characters. If you know, for example, that your key only used lowercase letters and numbers, you can speed up the search by specifying a list of characters explicitly. This option is mutually exclusive with -n.|
|Allow non-printable characters in keys. By default, ccguess will only try printable ASCII characters. Note that the use of this option slows down the search significantly. This option is mutually exclusive with -t.|
file The name of a file that has been encrypted with the unknown key. This file is only read from, not written to. The special filename "-" is used to denote standard input.
If multiple files are specified, ccguess will search for keys that match any of the files, but will print a warning for keys that do not match all of the files.
Suppose the file myfile.cpt has been encrypted with the key "gardenhouse", but the user remembers "gardenhose". The commandwill find the correct key after 2318 guesses.
ccguess -K gardenhose myfile.cpt
The exit status is 0 if at least one possible match is found, 1 if no matches are found, and >=2 if an error occurred.
