Could you please suggest any good references for beginners.
You would need to first load the key from the file to create an EVP_PKEY
object. For example you could use the PEM_read_PUB
Hi Matt,
I'm trying to craft a client hello packet using a C program. I'm learning
about these keys, openssl, TLS etc.
So
openssl ecparam -name secp256r1 -genkey -out pvtkey.pem
openssl ec -in pvtkey.pem -pubout -out pubkey.pem
openssl pkey -in pubkey.pem -pubin -noout -text
will give me the 65

hello,
I'm trying to generate public/private keys with following commands:

I'm seeing the sizeof private key as 164 bytes and public key as 124 bytes.
In a wi
Understood. Thanks alot.
But I'm still Not able to understand why it is 65 bytes in the key value.
Thanks & Regards

You need to do base64 decoding to find out the real size of the ASN.1
encoded data.

hi,
please check the following :
==
$ openssl ecparam -name secp256r1 -genkey -out pvtkey.pem
using curve name prime256v1 instead of secp256r1
$ cat pvtkey.pem

Hi Lokesh,
I am not sure how do you count the sizes of 164 bytes and 124 bytes for
the pem files.
If I use -outform DER (and use -noout with the ecparam to avoid
outputting the params because the private key already contains info
about the params used) I see the following sizes for the DER encode
