   1 //! The DNS provides a single, global, hierarchical namespace with (when DNSSEC is used)
   2 //! cryptographic guarantees on all of its data.
   3 //!
   4 //! This makes it incredibly powerful for resolving human-readable names into arbitrary, secured
   5 //! data.
   6 //!
   7 //! Unlike TLS, this cryptographic security provides transferable proofs which can convince an
   8 //! offline device, using simple cryptographic primitives and a single root trusted key, of the
   9 //! validity of DNS data.
  10 //!
  11 //! This crate implements the creation and validation of such proofs, using the format from RFC
  12 //! 9102 to create transferable proofs of DNS entries.
  13 //!
  14 //! It is no-std (but requires `alloc`) and seeks to have minimal dependencies and a reasonably
  15 //! conservative MSRV policy, allowing it to be used in as many places as possible.
