6 openssl-passwd - compute password hashes
7
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
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
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).
