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.
