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.
