Looks Ok, but I see no mention of an interface to encryption hardware
That is a big sticking point for us.

This project seems very young and doesn't seem to have a very big user or
developer base. Too high risk for a commercial product.

Yes, I know OpenSSL is overkill for most embedded security needs. However,
it is the most active, used, and tested tested of any SSL library. It has a long
history and doesn't seem to be going away anytime in the near future.

It also has some focus on using encryption hardware accelerators through their
ENGINE interface. Although, it currently has some limitations, but
it's a start in
the right direction.

Also, the OpenSSL code is pretty modular. I think I can slice and dice it and
make it configurable enough that the memory footprint would be reasonable
for the desired functionality.

For these reasons, I think an open port of OpenSSL to eCos would be worthwhile.

I would still like to hear if this is of interest to anyone else and
get some input from
the eCos maintainers.

I know those from eCosCentric probably aren't too happy to hear about the
possibilities of a completely open port of the latest OpenSSL library for eCos,
since this would be in direct opposition to their ecos-SecureSockets product
(which is a closed port of OpenSSL v1.0.0a).

I would still like to know the answer to this, before I go off and upset someone
for cross posting.
