secp256r1 65 byte key size in packet capture

[Lokesh Chakka]

hello,

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

openssl ecparam -name secp256r1 -genkey -out pvtkey.pem
openssl ec -in pvtkey.pem -pubout

I'm seeing the sizeof private key as 164 bytes and public key as 124 bytes.

In a wireshark capture( attached ), I'm seeing key length as 65 bytes.

Can someone help me understand why the difference?

Thanks & Regards
