PASSWD(1)                    OpenSSL                    PASSWD(1)

NAME

     openssl-passwd, 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.
