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
- Like --method=md5crypt.
- 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.
- A list of options which will be evaluated before the ones specified on the
If the --stdin option is used then passwords containing some control
characters may not be read correctly.
This programs suffers of a bad case of featuritis.
