Hi Nils,
Now you got my point but the code on which I am working uses the
too much internals of those structures .That why I needed the change
log.Inold OpenSSL code for the EC_KEY_METH_DATA they used some
ECDSA_DATA_new() as
follows
EC_KEY *key ;
/*
some code
*/ key->meth_data = (EC_KEY_METH_DATA *)ECDSA_DATA_new();
In new version EC_KEY_METH _DATA is replaced by EC_EXTRA_DATA but I dont
know what is the replacement of ECDSA_DATA_new as this is not available in
new version.
Above like that I am facing some more issues wit internal structures in ECC
of OpenSSL
between Old version and latest version.
Regarding K163 I want to know the curve parameters whose nid was 548 in that
old version of OpenSSL .because this is the only hint to get the
corrosponding curve in new OpenSSL.
Thanks,
Abhishek

ok, you have used a pre-release version of openssl 0.9.8. Well,
shortly before 0.9.8 was released some API changes has been made,
for example the internals of almost all ec structures has been
put in internal header files, additional set/get functions has
been added and some names has been changed ...

that's correct but unless you really need to access the internals
of those structures it shouldn't really matter for you.

if you get a local copy of the openssl repository with rsync should
be able to checkout a version at a specific date

you mean something like EC_GROUP_cmp() ?
