I did dig arround more on the ecparam and ec options. Having a limited
knowledge on cryptograpy and specifically ecc key algorithm, and
experimenting with the CLI, I would like to clarify my understanding on
coverting the form of ecc key from compressed to uncompressed and vice
versa.
My
My understanding is that to convert the form of ecc key from compressed to
uncompressed and from uncompressed to compressed require the knowledge of
the ECC private key.
Is my understanding correct?
You might want to have a look at sections 2.3.3 and 2.3.4 in

Okay, I am in to my office for few minutes to get the details. Here is how I
am compiling and linking, and the error message I am getting. I have placed
elipses (...) where the file and object names were. What do I need to do to
get static linking to libcrypto.a to work?
g++ ... -O3

I'll try changing the order of the libraries as you suggest. As for telling
the linker that I wanted a static link, I am doing the project in Eclipse and
put it in the flags area. It comes out in the compile:
g++ ... -O3 -Wall -static -c -fmessage-length=0
I do want the executable to be as

Hi,
I have few queries regarding OpenSSl 0.9.8 :
1. Does it have 64-bit support? If not, which version(s) support
64-bit arch?
2. RHEL version(s) supported
3. GCC version(s) supported
Thanks and regards,
Nilesh
I have to extract a binary (unsigned char *) representation of a public
key from an ECDSA openssl key structure. Later, I want to use that binary
to reconstruct an openssl public key structure that I can use to verify a
signature. The curve is fixed - P521.
I don't need any certificates,

It would certainly help if you actually knew what it was saying,
not just believed it! And wasn't it rather libldap.so, not

Although I've been programming on various platforms for quite awhile, I don't
know much about the principles involved here - i.e. Linux or static vs dynamix
linking. You are right, it is linking to libldap.

Some incredibly helpful advice, which I appreciate very much. I'll apply it
all tomorrow morning. It makes a lot of
sense to find out that I've been putting the -static flag in the wrong place,
because I had to develop scripts to temporarily
hide shared libraries from the linker, whenever I

Hi Ciprian,
Thanks for the immediate reply .
I have some questions on both the approaches suggested.
You can create a file where you may concatenate all your trusted
certificates in PEM format and use that file for verification.
