Trust-DNS provides a binary for hosting or forwarding DNS zones.
This a named implementation for DNS zone hosting. It is capable of performing signing all records in the zone for server DNSSec RRSIG records associated with all records in a zone. There is also a
named binary that can be generated from the library with
cargo install trust-dns. Dynamic updates are supported via
SIG0 (an mTLS authentication method is under development).
- Dynamic Update with sqlite journaling backend (SIG0)
- DNSSEC online signing (NSEC not NSEC3)
- DNS over TLS (DoT)
- DNS over HTTPS (DoH)
- Forwarding stub resolver
- ANAME resolution, for zone mapping aliass to A and AAAA records
- Additionals section generation for aliasing record types
Support of TLS on the Server is managed through a pkcs12 der file. The documentation is captured in the example test config file, example.toml. A registered certificate to the server can be pinned to the Client with the
add_ca() method. Alternatively, as the client uses the rust-native-tls library, it should work with certificate signed by any standard CA.
DoT and DoH are supported. This is accomplished through the use of one of
rustls is currently supported for DoH). The Resolver requires only requires valid DoT or DoH resolvers being registered in order to be used.
To use with the
HttpsClientConnection should be used. Similarly, to use with the tokio
HttpsClientStream should be used. ClientAuth, mTLS, is currently not supported, there are some issues still being worked on. TLS is useful for Server authentication and connection privacy.
To enable DoT one of the features
dns-over-rustls must be enabled,
dns-over-https-rustls is used for DoH.
Currently the root key is hardcoded into the system. This gives validation of DNSKEY and DS records back to the root. NSEC is implemented, but not NSEC3. Because caching is not yet enabled, it has been noticed that some DNS servers appear to rate limit the connections, validating RRSIG records back to the root can require a significant number of additional queries for those records.
Zones will be automatically resigned on any record updates via dynamic DNS. To enable DNSSEC, one of the features
dnssec-rustls must be enabled.
- Distributed dynamic DNS updates, with consensus
- mTLS based authorization for Dynamic Updates
- Online NSEC creation for queries
- Full hint based resolving
- Maybe NSEC3 and/or NSEC5 support
The current minimum rustc version for this project is
Trust-DNS does it's best job to follow semver. Trust-DNS will be promoted to 1.0 upon stabilization of the publicly exposed APIs. This does not mean that Trust-DNS will necessarily break on upgrades between 0.x updates. Whenever possible, old APIs will be deprecated with notes on what replaced those deprecations. Trust-DNS will make a best effort to never break software which depends on it due to API changes, though this can not be guaranteed. Deprecated interfaces will be maintained for at minimum one major release after that in which they were deprecated (where possible), with the exception of the upgrade to 1.0 where all deprecated interfaces will be planned to be removed.
