This patch adds a few tests for Alternator over HTTPS (encrypted HTTP,
a.k.a. TLS or SSL). The tests are skipped unless run with "--https", so
they will not be run in CI. Nevertheless, they are useful to improve
our understanding on how DynamoDB works over HTTPS and can be a basis
for adding more tests for HTTPS support. The included tests pass on both
Alternator and AWS DynamoDB.
One test checks that both TLS 1.2 and TLS 1.3 are properly supported,
and if chosen by the client, are actually honored. The same test also
checks that TLS 1.1 is not supported, and results with a proper error
if attempted. Both AWS DynamoDB and Alterator support the same protocols.
Another test verifies that HTTP (unencrypted) requests cannot be sent
over an HTTPS port. This is important for security - an installation
that chooses to allow only HTTPS wants users to only use encrypted
connections, and would not want users to continue sending unencrypted
requests to the HTTPS port.
