Linux 2.6 - man page for mkpasswd (linux section 1)

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.
