PASSWD(1)                           OpenSSL                          PASSWD(1)

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 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.
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 terminal.
       -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.
