NAME

6       mkpasswd - Overfeatured front end to crypt(3)
7

SYNOPSIS

9       mkpasswd PASSWORD SALT
10

DESCRIPTION

12       mkpasswd  encrypts  the  given password with the crypt(3) libc function
13       using the given salt.
14

OPTIONS

16       -S, --salt=STRING
17              Use the STRING as salt. It must not  contain  prefixes  such  as
18              $1$.
19
20       -R, --rounds=NUMBER
21              Use NUMBER rounds. This argument is ignored if the method chosen
22              does not support  variable  rounds.  For  the  OpenBSD  Blowfish
23              method  this  is  the  logarithm  of  the number of rounds.  The
24              behavior is undefined if this option is used without --method.
25
26       -m, --method=TYPE
27              Compute the password using the TYPE method.   If  TYPE  is  help
28              then  the available methods are printed.  If TYPE begins and end
29              with $ characters then the string is passed to  crypt_gensalt(3)
30              as-is.
31
32       -5     Like --method=md5.
33
34       -P, --password-fd=NUM
35              Read the password from file descriptor NUM instead of using get‐
36              pass(3).  If the file descriptor is not connected to a tty  then
37              no other message than the hashed password is printed on stdout.
38
39       -s, --stdin
40              Like --password-fd=0.
41

ENVIRONMENT

43       MKPASSWD_OPTIONS
44              A  list  of options which will be evalued before the ones speci‐
45              fied on the command line.
46

BUGS

48       If the --stdin option is used, passwords containing some control  char‐
49       acters may not be read correctly.
50
51       This programs suffers of a bad case of featuritis.
