NAME

6       openssl-passwd - compute password hashes
7

SYNOPSIS

9       openssl passwd [-help] [-1] [-apr1] [-aixmd5] [-5] [-6] [-salt string]
10       [-in file] [-stdin] [-noverify] [-quiet] [-table] [-reverse] [-rand
11       files] [-writerand file] [-provider name] [-provider-path path]
12       [-propquery propq] [password]
13

DESCRIPTION

15       This command computes the hash of a password typed at run-time or the
16       hash of each password in a list.  The password list is taken from the
17       named file for option -in, from stdin for option -stdin, or from the
18       command line, or from the terminal otherwise.
19

OPTIONS

21       -help
22           Print out a usage message.
23
24       -1  Use the MD5 based BSD password algorithm 1 (default).
25
26       -apr1
27           Use the apr1 algorithm (Apache variant of the BSD algorithm).
28
29       -aixmd5
30           Use the AIX MD5 algorithm (AIX variant of the BSD algorithm).
31
32       -5
33       -6  Use the SHA256 / SHA512 based algorithms defined by Ulrich Drepper.
34           See <https://www.akkadia.org/drepper/SHA-crypt.txt>.
35
36       -salt string
37           Use the specified salt.  When reading a password from the terminal,
38           this implies -noverify.
39
40       -in file
41           Read passwords from file.
42
43       -stdin
44           Read passwords from stdin.
45
46       -noverify
47           Don't verify when reading a password from the terminal.
48
49       -quiet
50           Don't output warnings when passwords given at the command line are
51           truncated.
52
53       -table
54           In the output list, prepend the cleartext password and a TAB
55           character to each password hash.
56
57       -reverse
58           When the -table option is used, reverse the order of cleartext and
59           hash.
60
61       -rand files, -writerand file
62           See "Random State Options" in openssl(1) for details.
63
64       -provider name
65       -provider-path path
66       -propquery propq
67           See "Provider Options" in openssl(1), provider(7), and property(7).

EXAMPLES

70         % openssl passwd -1 -salt xxxxxxxx password
71         $1$xxxxxxxx$UYCIxa628.9qXjpQCjM4a.
72
73         % openssl passwd -apr1 -salt xxxxxxxx password
74         $apr1$xxxxxxxx$dxHfLAsjHkDRmG83UXe8K0
75
76         % openssl passwd -aixmd5 -salt xxxxxxxx password
77         xxxxxxxx$8Oaipk/GPKhC64w/YVeFD/
