NAME

6       openssl-passwd, passwd - compute password hashes
7

SYNOPSIS

9       openssl passwd [-help] [-crypt] [-1] [-apr1] [-aixmd5] [-5] [-6] [-salt
10       string] [-in file] [-stdin] [-noverify] [-quiet] [-table] [-rand
11       file...]  [-writerand file] {password}
12

DESCRIPTION

14       The passwd command computes the hash of a password typed at run-time or
15       the hash of each password in a list.  The password list is taken from
16       the named file for option -in file, from stdin for option -stdin, or
17       from the command line, or from the terminal otherwise.  The Unix
18       standard algorithm crypt and the MD5-based BSD password algorithm 1,
19       its Apache variant apr1, and its AIX variant are available.
20

OPTIONS

22       -help
23           Print out a usage message.
24
25       -crypt
26           Use the crypt algorithm (default).
27
28       -1  Use the MD5 based BSD password algorithm 1.
29
30       -apr1
31           Use the apr1 algorithm (Apache variant of the BSD algorithm).
32
33       -aixmd5
34           Use the AIX MD5 algorithm (AIX variant of the BSD algorithm).
35
36       -5
37       -6  Use the SHA256 / SHA512 based algorithms defined by Ulrich Drepper.
38           See <https://www.akkadia.org/drepper/SHA-crypt.txt>.
39
40       -salt string
41           Use the specified salt.  When reading a password from the terminal,
42           this implies -noverify.
43
44       -in file
45           Read passwords from file.
46
47       -stdin
48           Read passwords from stdin.
49
50       -noverify
51           Don't verify when reading a password from the terminal.
52
53       -quiet
54           Don't output warnings when passwords given at the command line are
55           truncated.
56
57       -table
58           In the output list, prepend the cleartext password and a TAB
59           character to each password hash.
60
61       -rand file...
62           A file or files containing random data used to seed the random
63           number generator.  Multiple files can be specified separated by an
64           OS-dependent character.  The separator is ; for MS-Windows, , for
65           OpenVMS, and : for all others.
66
67       [-writerand file]
68           Writes random data to the specified file upon exit.  This can be
69           used with a subsequent -rand flag.
70

76         $1$xxxxxxxx$UYCIxa628.9qXjpQCjM4a.
77
78         % openssl passwd -apr1 -salt xxxxxxxx password
79         $apr1$xxxxxxxx$dxHfLAsjHkDRmG83UXe8K0
80
81         % openssl passwd -aixmd5 -salt xxxxxxxx password
