       openssl-passwd - compute password hashes


       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]


       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.


           Print out a usage message.

       -1  Use the MD5 based BSD password algorithm 1 (default).

           Use the apr1 algorithm (Apache variant of the BSD algorithm).

           Use the AIX MD5 algorithm (AIX variant of the BSD algorithm).

       -6  Use the SHA256 / SHA512 based algorithms defined by Ulrich Drepper.
           See <>.

       -salt string
           Use the specified salt.  When reading a password from the terminal,
           this implies -noverify.

       -in file
           Read passwords from file.

           Read passwords from stdin.

           Don't verify when reading a password from the terminal.

           Don't output warnings when passwords given at the command line are

           In the output list, prepend the cleartext password and a TAB
           character to each password hash.

           When the -table option is used, reverse the order of cleartext and

       -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).


         % openssl passwd -1 -salt xxxxxxxx password

         % openssl passwd -apr1 -salt xxxxxxxx password

         % openssl passwd -aixmd5 -salt xxxxxxxx password


       The -crypt option was removed in OpenSSL 3.0.
