Hello
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

Hello,
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.
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,

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
Hello,
Marek: I suspect Markus is referring to ECIES (Elliptic Curve
Integrated Encryption Scheme) as specified in ANSI X9.63 and the IEEE
P1363a Draft.
OK, thank you for information.
Best regards,

Does that mean that ECICS is not implemented yet?
What is ECICS ? I can not find any information :-(
I'm sure OpenSSL implements generic EC algorithms, ECDSA and ECDH
Sorry, that was a typo, I meant ECIES, of course.
It seems that I spent

ECDSA functions works in general on BIGNUM's (packed in some structures)
