       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 number 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.
