use CApath for certificates and store certificates (v2)
CApath is about 20% faster than CAfile so use it, also save the received certificates from the servers for later analysis (proper hostname checking, looking for certificates sharing private key, etc.) Use the mechanism from cipherscan to find location of ca cert bundle
