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 chosen 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.

       -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.
