x509-cert: provide parsing profiles #987

baloo · 2023-04-05T16:42:48Z

This allow the user to relax checks when parsing certificate and cover for non rfc5280 compliant x509 certificates.

Fixes #978
Fixes #984

@baloo this needs a rebase

der/derive/src/attributes.rs

baloo · 2023-04-18T03:29:51Z

I guess I will need to split the der/derive changes in another PR, get those released and need a PR to fix both fuzz and the minimal-version checks
see #1008

the parsing profiles (RustCrypto#987) rely on a PhantomData field to specify the underlying profile used when parsing. This is specified like: ``` rust pub struct TbsCertificate<P: Profile = Rfc5280> { // ... #[asn1(skipped = "Default::default")] pub(crate) _profile: PhantomData<P>, } ```

tarcieri · 2023-04-18T13:00:23Z

Let me take a stab at PhatomData handling with derive...

baloo · 2023-04-18T18:33:16Z

Yeah, I was focusing on providing a EncodeValue implementation, and missed that I needed Encode itself.

That works, I also needed DerOrd and ValueOrd.
~~this is rebased on #1012~~

tarcieri · 2023-04-19T13:40:16Z

Hmm, so #1012 didn't fix the issue? Does it pass locally?

tarcieri · 2023-04-19T16:27:10Z

This one is a straight up test failure: https://github.com/RustCrypto/formats/actions/runs/4736068365/jobs/8427760079?pr=987

baloo · 2023-04-19T16:27:54Z

yes, I deleted my previous comment and trying to figure out what is happening right now.

baloo · 2023-04-19T16:49:47Z

Because I dropped the handling for generics in the derive at the same time as I dropped the handling for the skipped fields.
I still need the der_derive to handle type generics.

tarcieri · 2023-04-19T17:12:28Z

@baloo aah yeah, to properly handle generics it should probably be using Generics::split_for_impl

baloo · 2023-04-19T18:32:08Z

@tarcieri injecting a default lifetime with split for impl in wasn't trivial but this is the best I came up with. I'd love your opinion

baloo · 2023-04-20T03:24:03Z

alright so that solved that.

Folks seems to be relying on `TbsCertificate` directly, we should avoid an API break as much as possible.

lumag · 2023-04-20T13:55:35Z

@baloo this now breaks building certificates:

error: cannot construct `TbsCertificateInner` with struct literal syntax due to private fields
   --> src/cert_gen.rs:105:43
    |
105 |     let tbs_certificate: TbsCertificate = TbsCertificate {
    |                                           ^^^^^^^^^^^^^^
    |
    = note: ... and other private field `_profile` that was not provided

error: could not compile `foo` due to previous error

tarcieri · 2023-04-20T14:02:24Z

Oof, that seems bad. That's another argument for keeping the generic parameters off every type except Certificate

lumag · 2023-04-20T14:07:18Z

Exporting the PhantomData should work

tarcieri · 2023-04-20T14:10:28Z

yes, albeit a bit ugly to have PhantomData in a public API

lumag · 2023-04-20T14:26:23Z

For me this is not a big problem, since I will most likely rewrite my code to use CertificateBuilder. But you should at least be aware of thi problem.

baloo · 2023-04-20T15:24:58Z

We can either revert the thing for now and rework that, or get a constructor (new) for the TbsCertificate ~~and the Certificate~~.

baloo · 2023-04-20T15:45:00Z

or we just get rid of the phantom data there ... #1017
