Optional features

In Hvicorn, there are some features that are not commonly used because they are in experimental status or have shortcomings. This page will list these features.

Bypass GFW DNS poisoning

Since 2024/6, hack.chat has been blocked in China using DNS poisoning based on domain name. This feature can be enabled by using bot.optional_features.bypass_gfw_dns_poisoning = True to run Hvicorn within China. However, this feature points the connection to an IP address, which does not match the hostname, so SSL verification must be disabled, which leads to vulnerability to potential easy MitM attack.
