       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

       -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 truncated.

           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 $1$xxxxxxxx$UYCIxa628.9qXjpQCjM4a..

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