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 chosen
              does not support  variable  rounds.  For  the  OpenBSD  Blowfish
              method this is the logarithm of the number of rounds.

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

       -5     Like --method=md5.

       -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.
