Openssl programming

[Gloria]

Hi,
I have a question,
Im trying to add crypto algorithm into Openssl,
I heard about the engine(ccgost), and read the README.txt file, but I don't understand how to do it..
I wonder If I add my own algorithm, Do I just copy ccgost pattern? or have to change entire openssl core source??..
Besides that, I want to know how to use ccgost engine, It's very hard for me.
Thanks,...

I think you're too late. It looks like it's already been added in the OpenSSL CVS repository.

From the README:

GOST ENGINE

This engine provides implementation of Russian cryptography standard. This is also an example of adding new cryptoalgorithms into OpenSSL without changing its core. If OpenSSL is compiled with dynamic engine support, new algorithms can be added even without recompilation of OpenSSL and applications which use it.

But why? I think SSL (or TLS) already has something like 9 encryption choices. Is this algorithm better?
