mkdhparams(8)

NAME

   mkdhparams - create DH parameter file

SYNOPSIS

   /usr/sbin/mkdhparams

DESCRIPTION

   This script creates new DH parameters and saves them in
   /etc/courier/dhparams.pem. If this file already exists and it's less
   than 25 days old, the script returns immediately. If this file is over
   25 days old, new DH parameters get generated and the file gets
   replaced.

   This script is intended to be execute when the system boots, or from a
   monthly cron job.

FILES

   /etc/courier/dhparams.pem
       DH Parameter file.

ENVIRONMENT VARIABLES

   BITS
       Customize the DH parameter bit size. The default value depends on
       whether this script uses OpenSSL or GnuTLS libraries. For OpenSSL
       the default number of bits is 2048. GnuTLS uses a security level
       setting, rather than the number of bits, and the default security
       level is "high".

       Note
       It make take several minutes to generate new DH parameters with the
       default strength.
