## OPTIONS

- **-a x**

  set minimum length of passphrase

- **-b x**

  set maximum length

- **-m x**

  set guessing mode:\
      **incremental**: try them all\
      **random**: try at random\
      **file**: read phrases from file (use -i)

- **-i x**

  file to read the passphrases from

  charset, one or more from the following:\
      a: a-z\
      A: A-Z\
      0: 0-9\

## ISSUES

Nasty will not work if you try it with a gpg-agent running in your system. For obvious reasons the agent will ask you the passphrase to access your private key - which you probably don't record, right? :)
