libtls is a high-level secure sockets API provided as part of the LibreSSL project
libtls provides an alternative, "idiot-proof" API for working with secure sockets. Instead of directly using the complex OpenSSL-compatible API underlying LibreSSL, libtls provides a much simpler API that comes with sane defaults and dramatically cuts down on the number of decisions developers have to make to create a secure connection.
The current, somewhat anemic documentation can be found on the LibreSSL project site.
Note that this tag should only be used for the high-level libtls API. For the core LibreSSL library, you will likely want to use libressl or openssl, depending on the context.
