NAME
openssl-passwd - compute password hashes
SYNOPSIS
openssl passwd [-help] [-1] [-apr1] [-aixmd5] [-5] [-6] [-salt string] [-in file] [-stdin] [-noverify] [-quiet] [-table] [-reverse] [-rand files] [-writerand file] [-provider name] [-provider-path path] [-propquery propq] [password]
DESCRIPTION
This 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, from stdin for option -stdin, or from the command line, or from the terminal otherwise.
OPTIONS
-help
Print out a usage message.
|
-1 |
Use the MD5 based BSD password algorithm 1 (default). |
-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.
-reverse
When the -table option is used, reverse the order of cleartext and hash.
-rand files, -writerand file
See "Random State Options" in openssl(1) for details.
-provider name
-provider-path path
-propquery propq
See "Provider Options" in openssl(1), provider(7), and property(7).
