└─>TIPC encryption support
In linux kernel since version 5.1 (release Date: 2019-05-05)  
Saying Y here will enable support for TIPC encryption.
All TIPC messages will be encrypted/decrypted by using the currently most
advanced algorithm: AEAD AES-GCM (like IPSec or TLS) before leaving/
entering the TIPC stack.
Key setting from user-space is performed via netlink by a user program
(e.g. the iproute2 'tipc' tool).
