                         **************************

Modern TLS protocols require elliptic curve cryptography, ephemeral keys and
Diffie-Hellman key exchange.  This is dependent on the availability of files
containing "safe prime" numbers in PEM format.  Ideally these are generated on
a per-site basis.  This can take *considerable* time depending on platform.

  $ SET DEFAULT WASD_ROOT:[LOCAL]
  $ OPENSSL DHPARAM -OUT DH_PARAM_512.PEM 512
  $ OPENSSL DHPARAM -OUT DH_PARAM_1024.PEM 1024
  $ OPENSSL DHPARAM -OUT DH_PARAM_2048.PEM 2048

Alternatively, when using the WASD OpenSSL package, the procedure

  $ @WASD_ROOT:[SRC.OPENSSL-1_n_n.WASD]CREATE_EPHEMERAL_DH_PARAM.COM

will generate the "safe prime" files as above, or as another alternative,
fresh "safe prime" files are generated with each release and can be copied
directly from the package.

  $ SET DEFAULT WASD_ROOT:[LOCAL]
  $ COPY [SRC.OPENSSL-1_0_n.WASD.CERT]DH_PARAM_*.PEM *
  $! or
  $ COPY [SRC.OPENSSL-1_1_n.WASD]DH_PARAM_*.PEM *
  $! depending on the WASD OpenSSL version

One of these three should be done after the install/update procedure concludes
and before starting the server.  Any can be repeated at any time and takes
effect at next server startup.
