mkpasswd - Overfeatured front end to
crypt(3)
mkpasswd PASSWORD [
SALT]
mkpasswd encrypts the given password with the
crypt(3) libc
function, using the given salt.
-
-S, --salt=STRING
- Use the STRING as salt. If it begins with $
then it will be passed straight to crypt(3) without any
checks.
-
-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 list of available methods is printed.
If TYPE begins and end with $ characters then the string is
passed to crypt_gensalt(3) as-is.
- -5
- Like --method=md5crypt.
-
-P NUM,
--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 text than the hashed password is printed on stdout.
-
-s, --stdin
- Like --password-fd=0.
- MKPASSWD_OPTIONS
- A list of options which will be evaluated before the ones
specified on the command line.
If the
--stdin option is used then passwords containing some control
characters may not be read correctly.
This program suffers of a bad case of featuritis.
