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.   The  behavior  is  undefined  if  this option is used without
              --method.

       -m, --method=TYPE
              Compute the password using the TYPE method.  If TYPE is  help  then  the  available
              methods  are  printed.  If TYPE begins and end with $ characters then the string is
              passed to crypt_gensalt(3) as-is.

       -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.
