This repo has a handful of APIs to create and verify RFC 9102 proofs.
It has minimal dependencies (bitcoin_hashes for hashing operations, hex_lit for some hex constants, and optionally tokio for networking in some APIs).
There are numerous APIs present:
- Building the crate as a library provides a handful of DNS types, including (de)serialization for them.
- Building the crate as a library with the
validation
feature also enables thevalidation
module, which allows for verification of an RFC 9102 proof. - Building the crate as a library with the
std
feature enables thequery
module which can build an RFC 9102 proof using repeated queries to any standard DNS server (including over DoH). - The
wasmpack
directory anduniffi
directory expose very simplified APIs to build and verify RFC 9102 proofs either in WASM (via wasm-pack, see-also thewasmpack/doh_lookup.js
file which can build RFC 9102 proofs using repeated queries to a DoH server directly from JavaScript) or any language supported byuniffi
. - Building the the
http_proof_gen
binary in the crate builds an HTTP server which responds to requests for RFC 9102 proofs in the form/dnssecproof?d=domain&t=rr_type
, returning the binary proof containing and proving the Resource Record of typerr_type
atdomain
.
The slower_smaller_binary
feature slows proof validation down by 50%+ for a
very marginal reduction in binary size, but those who are extremely binary size
constrained may still find it useful.
See https://docs.rs/dnssec-prover for full API details on the Rust API. There's also a website which demonstrates the WASM build of this crate at https://http-dns-prover.as397444.net/ which allows for making validated queries.
