6 mkpasswd - Overfeatured front end to crypt(3)
7
9 mkpasswd PASSWORD [SALT]
10
12 mkpasswd encrypts the given password with the crypt(3) libc function,
13 using the given salt.
14
16 -S, --salt=STRING Use the STRING as salt. If it begins with $ then
17 it will be passed straight to crypt(3) without any checks.
18
19 -R, --rounds=NUMBER Use NUMBER rounds. This argument is ignored if
20 the method chosen does not support variable rounds. For the
21 OpenBSD Blowfish method this is the logarithm of the number of
22 rounds. The behavior is undefined if this option is used with‐
23 out --method.
24
25 -m, --method=TYPE Compute the password using the TYPE method. If
26 TYPE is help then the list of available methods is printed. If
27 TYPE begins and end with $ characters then the string is passed
28 to crypt_gensalt(3) as-is.
29
30 -5 Like --method=md5crypt.
31
32 -P NUM, --password-fd=NUM Read the password from file descriptor
33 NUM instead of using getpass(3). If the file descriptor is not
34 connected to a tty then no other text than the hashed password
35 is printed on stdout.
36
37 -s, --stdin
38 Like --password-fd=0.
39
41 MKPASSWD_OPTIONS
42 A list of options which will be evaluated before the ones speci‐
43 fied on the command line.
44
46 If the --stdin option is used then passwords containing some control
47 characters may not be read correctly.
48
49 This programs suffers of a bad case of featuritis.

52 passwd(1), passwd(5), crypt(3), crypt(5), crypt_gensalt(3), getpass(3).
