Resubmit out of date proof by traversing from the leaf

So suppose you have

a.b.c.d
  b.c.d
    c.d
      d.

If c.d is up to date, submit b.c.d and a.b.c.d (in that order)

Check if inserted +ttls is in the past or not on the rrset result

Currently it is only checking if the proof hash generated by the tool and the one in the DNSSEC oracle is same but need to check the expiration as well

Return an error if the DNS data is older than the oracle's

It can happen if you get a stale DNS entry

Skipping RRSIG=8594/13 on TXT RRSET for _ens.example.xyz: Unknown algorithm

I got this error when trying to register at https://app.ens.domains Skipping RRSIG=8594/13 on TXT RRSET for _ens.example.xyz: Unknown algorithm

Add missing algorithm and digest

https://github.com/ensdomains/dnsprovejs/blob/master/src/prove.ts#L197

take the list from https://github.com/ensdomains/ens-contracts/blob/master/deploy/dnssec-oracle/10_deploy_oracle.js#L71
All just return true.

AC

Test all these names work

- putbtc.com
- butta.io 
- craxyhu.xyz
- markemil.io

Signature verification always returns true

Is this intended?

Rewrite dnsprovejs

We'd like to have a robust, reusable component for creating, publishing, and checking DNSSEC proofs. This library provides a starting point, but needs substantial work.

We'd like to see a rewrite, with the following goals:

A query method that takes a record type and name, and returns a result with cryptographic proof where available. Basic functionality (eg, without verifying proofs or recursing) should work without reference to a deployed contract.
Verification of the validity of the proofs before they're submitted to the chain (this could use deployed contracts to avoid reimplementing verification code).
Interface between query code and oracle should be as simple as possible, and available for implementation by other providers.
Configurable choice of supported DNSSEC algorithms and digests.
An API that distinguishes between different failure cases: Record does not exist, DNSSEC not enabled, unsupported algorithm, invalid proofs, expired signatures, etc. This is crucial so UIs can tell users exactly what needs to be fixed.
Configurable choice of DNS-over-HTTPS endpoint, with defaults.
Accepts a web3 provider, and does not require the user to use a specific web3 library.
Support for contracts that proxy the DNSSEC oracle - for instance, the DNS registrar.
Thoroughly documented API.
Extensive unit test coverage.
Implemented in TypeScript.

Interested participants should submit a proposed outline for the API before being approved to begin work.
