MKPASSWD(1)                              Debian GNU/Linux                             MKPASSWD(1)



NAME
       mkpasswd - Overfeatured front end to crypt(3)

SYNOPSIS
       mkpasswd PASSWORD SALT


DESCRIPTION
       mkpasswd encrypts the given password with the crypt(3) libc function using the given salt.

OPTIONS
       -S, --salt=STRING
              Use the STRING as salt. It must not contain prefixes such as $1$.

       -R, --rounds=NUMBER
              Use NUMBER rounds. This argument is ignored if the method choosen does not  support
              variable  rounds. For the OpenBSD Blowfish method this is the logarithm of the num-
              ber of rounds.

       -m, --method=TYPE
              Compute the password using the TYPE method.  If TYPE is  help  then  the  available
              methods are printed.

       -P, --password-fd=NUM
              Read  the  password  from  file descriptor NUM instead of using getpass(3).  If the
              file descriptor is not connected to a tty then no other  message  than  the  hashed
              password is printed on stdout.

       -s, --stdin
              Like --password-fd=0.

ENVIRONMENT
       MKPASSWD_OPTIONS
              A  list  of  options which will be evalued before the ones specified on the command
              line.

BUGS
       If the --stdin option is used, passwords containing some control  characters  may  not  be
       read correctly.

       This programs suffers of a bad case of featuritis.
