     NAME
          passwd - compute password hashes

     SYNOPSIS
          openssl passwd [-crypt] [-1] [-apr1] [-salt string] [-in
          file] [-stdin] [-quiet] [-table] {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, and from the command
          line otherwise.  The Unix standard algorithm crypt and the
          MD5-based BSD password algorithm 1 and its Apache variant
          apr1 are available.

     OPTIONS
          -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).

          -salt string
              Use the specified salt.

          -in file
              Read passwords from file.

          -stdin
              Read passwords from stdin.

          -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.

     EXAMPLES
          openssl passwd -crypt -salt xx password prints
          xxj31ZMTZzkVA.

          openssl passwd -1 -salt xxxxxxxx password prints
          $1$xxxxxxxx$UYCIxa628.9qXjpQCjM4a..

          openssl passwd -apr1 -salt xxxxxxxx password prints
          $apr1$xxxxxxxx$dxHfLAsjHkDRmG83UXe8K0.
