You need to take a closer look at RFC 2630 and RFC 2631. You might need to
generate a different ephemeral key for each recipient. You can use the
same one for multiple recipients if and only if they have the same p, q,
and g domain parameter values. The originator must use the recipient
domain parameters when generating the ephemeral key pair.

a list of products which implement Diffie-Hellman as per RFC 2631.
Also, when using Diffie-Hellman Ephemeral-Static mode, what key size do you
use to generate a new key pair. You could use the key size of the recipient,
but what if you are sending the same message to multiple recipients who may
have different DH key sizes. Another option is to use the size of your own
static DH key pair.
I would appreciate any advice or help with this.
Thanks in advance
