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 number 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.
