bpo-36076: Add SNI support to ssl.get_server_certificate. (GH-16820)#482
Merged
Conversation
Many servers in the cloud environment require SNI to be used during the SSL/TLS handshake, therefore it is not possible to fetch their certificates using the ssl.get_server_certificate interface. This change adds an additional optional hostname argument that can be used to set the SNI. Note that it is intentionally a separate argument instead of using the host part of the addr tuple, because one might want to explicitly fetch the default certificate or fetch a certificate from a specific IP address with the specified SNI hostname. A separate argument also works better for backwards compatibility. Automerge-Triggered-By: GH:tiran
