passwd - compute password hashes


   openssl passwd [-crypt] [-1] [-apr1] [-salt string] [-in file] [-stdin]
   [-noverify] [-quiet] [-table] {password}


   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 and
   its Apache variant apr1 are available.


       Use the crypt algorithm (default).

   -1  Use the MD5 based BSD password algorithm 1.

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

   -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.


   openssl passwd -crypt -salt xx password prints xxj31ZMTZzkVA.

   openssl passwd -1 -salt xxxxxxxx password prints

   openssl passwd -apr1 -salt xxxxxxxx password prints
