NAME

       bruteforce-wallet - try to find the password of an encrypted wallet file

SYNOPSIS

       bruteforce-wallet [options] <filename>

DESCRIPTION

       bruteforce-wallet try to find the password of an encrypted Peercoin (or Bitcoin, Litecoin,
       etc...) wallet file.  It can be used in two ways:

              •  Try all possible passwords given a charset.

              •  Try all passwords in a file (dictionary).

       bruteforce-wallet have the following features:

              •  You can specify the number of threads to use when cracking a file.

              •  Sending a USR1 signal to a running  bruteforce-wallet  process  makes  it  print
                 progress and continue.

              •  There are an exhaustive mode and a dictionary mode.

       In  the exhaustive mode the program tries to decrypt one of the encrypted addresses in the
       wallet by trying all the  possible  passwords.   It  is  especially  useful  if  you  know
       something  about  the password (i.e. you forgot a part of your password but still remember
       most of it).  Finding the password of a wallet without knowing  anything  about  it  would
       take  way too much time (unless the password is really short and/or weak).  There are some
       command line options to specify:

              •  The minimum password length to try.

              •  The maximum password length to try.

              •  The beginning of the password.

              •  The end of the password.

              •  The character set to use (among the characters of the current locale).

       In dictionary mode the program tries to decrypt one of  the  encrypted  addresses  in  the
       wallet  by  trying all the passwords contained in a file.  The file must have one password
       per line.

OPTIONS

       -b <string>
              Beginning of the password. The default value is "".

       -e <string>
              End of the password. Default: "".

       -f <file>
              Read the passwords from a file instead of generating them.

       -h     Show help and quit.

       -l <length>
              Minimum password length (beginning and end included). Default: 1.

       -m <length>
              Maximum password length (beginning and end included). Default: 8.

       -s <string>
              Password         character         set.          Default          value          is
              "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz"

       -t <n> Number of threads to use. Default: 1.

       -v <n> Print progress info every n seconds.

       -w <file>
              Restore the state of a previous session if the file exists, then write the state to
              the file regularly (~ every minute).

       Note: Sending a USR1 signal to a running bruteforce-wallet process makes it print progress
       info to standard error and continue.

LIMITATIONS

       The  program  currently only works on unix-like POSIX systems (e.g. GNU/Linux).  Different
       versions of BerkeleyDB are usually not compatible with each  other.   Therefore,  for  the
       program to work, you will have to check that the BerkeleyDB version you are using can read
       the databases created by the BerkeleyDB version your wallet was created with.

EXAMPLES

       Try to find the password of  an  encrypted  wallet  file  using  4  threads,  trying  only
       passwords with 5 characters:

           $ bruteforce-wallet -t 4 -l 5 -m 5 wallet.dat

       Try  to  find  the  password  of  an  encrypted  wallet  file using 8 threads, trying only
       passwords with 5 to 10 characters beginning with "W4l" and ending with "z":

           $ bruteforce-wallet -t 8 -l 5 -m 10 -b "W4l" -e "z" wallet.dat

       Try to find the password of  an  encrypted  wallet  file  using  8  threads,  trying  only
       passwords with 10 characters using the character set "P情8ŭ":

           $ bruteforce-wallet -t 8 -l 10 -m 10 -s "P情8ŭ" wallet.dat

       Try to find the password of an encrypted wallet file using 6 threads, trying the passwords
       contained in a dictionary file:

           $ bruteforce-wallet -t 6 -f dictionary.txt wallet.dat

       Print progress info:

           $ pkill -USR1 -f bruteforce-wallet

       Print progress info every 30 seconds:

           $ bruteforce-wallet -t 6 -f dictionary.txt -v 30 wallet.dat

       Save/restore state between sessions:

           $ bruteforce-wallet -t 6 -f dictionary.txt -w state.txt wallet.dat

           (Let the program run for a few minutes and stop it)

           $ bruteforce-wallet -t 6 -w state.txt wallet.dat
