support for newer SSL certificate types

more and more CAs are using certificates signed using SHA256 or SHA512,
whereas go's X.509 support by default only supports certificates signed
with a SHA1 hash.

Importing the two hashes causes them to be registered and available to
use for x509 which in turn allows connecting to servers using one of
these newer certificates
