NAME
       passwd - compute password hashes

SYNOPSIS
       openssl passwd [-crypt] [-1] [-apr1] [-salt string] [-in
       file] [-stdin] [-noverify] [-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, or from the com-
       mand 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.

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.  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 termi-
           nal.

       -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.
