Have checked this part of the spec:
Note that many implementations use (0, 0) as the reference point at infinity, which is not on the curve and should therefore be rejected.
I have feed the VerifyingKey::from_sec1_bytes with pk = [0;64] and it fails to get key, this is expected behaviour, just wanting to note it.

Thanks, added a test case for this
