Primarily it enables the Domain Name System (DNS) to authenticate updates to a DNS database. It is most commonly used to update Dynamic DNS or a secondary/slave DNS server. TSIG uses shared secret keys and one-way hashing to provide a cryptographically secure means of authenticating each endpoint of a GSS-TSIG and provides more granular update security policies than Windows Server DNS can support natively, including update policies that specify which GSS-TSIG attributes to identify update clients by, and explicit controls on which record types that client can … 2017-09-08 2019-03-19 GSS-TSIG (Generic Security Service Algorithm for Secret Key Transaction Authentication for DNS) is defined in RFC 3645.

debug_level 5 logging shows the following messages Basic calls have been implemented for a client-side library as well, but a more fleshed out implementation would be needed. The goal of this project is to implement more high-level calls handling DNS requests, such as UDP/TCP switchover and client-side GSS-TSIG cryptography. GSS-TSIG (Generic Security Service Algorithm for Secret Key Transaction) is an extension to the TSIG DNS authentication protocol for secure key exchange.
