Hi,
Is it possible to implement ECDSA and ECICS using OpenSSL? I did not
find anything in the documentation or the man pages, although I was
told that OpenSSL is capable of elliptic curve cryptography which had
been donated by sun.
Btw, are there any patent implications?
Thanks,
Markus

Elliptic curves are in OpenSSL 0.9.8e version.
EDCSA is
Hi Marek,
I am sorry to write you directly but I have posted my question twice on the
openssl site and for some reason it never get published.
I would like to use only the ECDSA, is there any simple way to compile it
alone (ofcourse with the modules it's using).
I have tried doing it manually, but

Hi Marek,
First I would like to thank you for your quick reply.
I just have one more small question :)
As far as I could see the ASN.1 is used basically to calculate the size of
the signature (at least on the ecdsa side). So if I know exactly the size of
the signatures then I can only remove the u

OK, thank you for information.

Sorry, that was a typo, I meant ECIES, of course.
It seems that I sp

ECDSA functions works in general on BIGNUM's (packed in some structures)
Hi Marek,
As I mentioned before, I am using the openSSL directory for its support for
the ECDSA. Which I need to implement the AACS standard. I am not sure you
are familiar with it, but in short the problem I am encountering right now
is that in the AACS Std the signatures are represented as 40 by
