NAME
openssl-passwd, passwd - compute password hashes
SYNOPSIS
openssl passwd [-help] [-crypt] [-1] [-apr1] [-aixmd5] [-5] [-6] [-salt
string] [-in file] [-stdin] [-noverify] [-quiet] [-table] [-rand
file...] [-writerand file] {password}
DESCRIPTION
The passwd command computes the hash of a password typed at run-time or
the hash of each password in a list. The password list is taken from
the named file for option -in file, from stdin for option -stdin, or
from the command line, or from the terminal otherwise. The Unix
standard algorithm crypt and the MD5-based BSD password algorithm 1,
its Apache variant apr1, and its AIX variant are available.
OPTIONS
-help
Print out a usage message.
-crypt
Use the crypt algorithm (default).
-1 Use the MD5 based BSD password algorithm 1.
-apr1
Use the apr1 algorithm (Apache variant of the BSD algorithm).
-aixmd5
Use the AIX MD5 algorithm (AIX variant of the BSD algorithm).
-5
-6 Use the SHA256 / SHA512 based algorithms defined by Ulrich Drepper.
See <https://www.akkadia.org/drepper/SHA-crypt.txt>.
-salt string
Use the specified salt. When reading a password from the terminal,
this implies -noverify.
-in file
Read passwords from file.
-stdin
Read passwords from stdin.
-noverify
Don't verify when reading a password from the terminal.
-quiet
Don't output warnings when passwords given at the command line are
truncated.
-table
In the output list, prepend the cleartext password and a TAB
character to each password hash.
-rand file...
A file or files containing random data used to seed the random
number generator. Multiple files can be specified separated by an
OS-dependent character. The separator is ; for MS-Windows, , for
OpenVMS, and : for all others.
[-writerand file]
Writes random data to the specified file upon exit. This can be
used with a subsequent -rand flag.
