Overview

Webauthn-rs

Webauthn is a modern approach to hardware based authentication, consisting of a user with an authenticator device, a browser or client that interacts with the device, and a server that is able to generate challenges and verify the authenticators validity.

Users are able to enroll their own tokens through a registration process to be associated to their accounts, and then are able to login using the token which performas a cryptographic authentication.

This library aims to provide useful functions and frameworks allowing you to integrate webauthn into rust web servers. This means the library implements the Relying Party component of the FIDO2 workflow. We provide template and example javascript to demonstrate the browser interactions required.

Examples

As this library aims to be usable in a variety of contexts, we have provided examples in the examples folder. These examples should demonstrate secure and valid use, so please report any issues found, and we'd love to see more examples contributed!

Known Supported Keys/Harwdare

Yubico 5c + MacOS 10.14 + Firefox/Edge
Yubico 5ci + iPadOS 14 + Safari/Brave
TouchID + iPadOS + Safari
Windows Hello + Windows 10 + Chrome

If your key/browser combination don't work (generally due to missing crypto routines) please open an issue so that I can help you generate vectors and add support!

FIDO Compliance

This library has been carefully implemented to follow the w3c standard for webauthn processing to ensure correct behaviour. However, not all elements of the standard are implemented (yet). This means the library is not yet FIDO compliant. It is a goal to improve this library to meet that standard over time as more test vectors and hardware becomes available, but the current focus has been on supporting the most popular key types.

Feedback

The current design of the traits and configuration is open to feedback on how it can be improved - please use this library and contact the project on what can be improved!

Why OpenSSL?

A question I expect is why OpenSSL rather than some other pure-Rust cryptographic providers. There are two major justfications.

The first is that if this library will be used in corporate or major deployments, then cryptographic audits may have to be performed. It is much easier to point toward OpenSSL which has already undergone much more review and auditing than using a series of Rust crates which (while still great!) have not seen the same level of scrutiny.

The second is that OpenSSL is the only library I have found that allows us to reconstruct an EC public key from it's X/Y points or an RSA public key from it's n/e for use with signature verification. Without this, we are not able to parse authenticator credentials to perform authentication.

feat(touchid-attest): initial implementation of touch id attestation

Implements #33.

Currently missing steps 4 and 5, and the validation of the certificate chain against Apple's root certificates.

[x] cargo fmt has been run

[x] cargo test has been run and passes

[x] documentation has been updated with relevant examples (if relevant)

Firefox 98 + Windows 11 + Windows Hello truncates aaguid

As we discussed, I updated to windows 11 and ran the compat test to try to collect a tpm vector. I still need to analyze the vectors to see what format we're using but was surprised by the number of failures

Please add any extra details here:

Browser version: Firefox 98.0
Type of authenticator hardware: Windows hello. My processor is a Ryzen 9 which I believe has a TPM module. I authenticated using my pin.
Any other details that may help

WebauthnBuilder and prelude don't exist

I'm reading through the docs and the examples, and attempting to replicate my own simple version, but most of the examples and tutorials seem to use WebauthnBuilder and prelude in webauthn_rs, but I can't find any mention of them existing or ever having existed in the docs. Am I missing something?

dependency serde_cbor is unmaintained

The dependency serde_cbor is unmaintained and is flagged on a "cargo audit". The serde_cbor maintainer recommends moving over to ciborium or minicbor. In my experience, the former is an easy replacement (though ymmv).

Last call for changes!

Last call for ideas! I want to do the next release soon and stop changing the api so much, so now is your time to give constructive feedback! From my side I will commit a fido metadata service library and parser first before I do the release, currently I'm thinking to do the next release on 16th of August.

Support U2F appid extension
Implements support for the appid extension for U2F backwards compatibility.

I've noticed that some types have been recently changed to return &str instead of a String, and I've considered doing the same here, but didn't want to complicate the code adding lifetimes, let me know if you'd prefer it that way and I can change it.

Might also want to change the parameter type from String to something like Into, which would make it easier to use both &str and String types directly.

Review public API

An open question is the ergonomics of the public API and how we expose datastorage traits and other methods of application integration. As this library hasn't been used in "production" yet, it's still an open question if the decisions I made were really correct or ergonomic to use for deployments.

If you have comments or feedback on the current API design, I'd love to know!

User verification logic

Re: the discussion here: https://github.com/kanidm/webauthn-rs/commit/9e3fd65de11594955790cc1ebb60e567398f0cfd

What do you think of this approach for dealing with the UV problem?

Register doesn't work on Firefox because I need to enter a PIN!?

I tested the axtix example on Fedora 32. Tested key: HyperFIDO Pro Mini, which is a Feitian K8 rebrand/OEM device with a LED and button.

But it is not working on Firefox 82. I can click register, Firefox asks about to make the keydata more anonymous. But after that, my key LED doesn't blink.

But when I try Chromium: Username "Test" and click Register Chomium asks for a PIN. After entering the PIN to Unlock The LED of the key blinks and after pressing the button, registeration is compleed.

Then when I go back to firefox. Only login works.

So I wonder why Firefox doesn't support a PIN. Second why does your example needs that PIN? Maybe can we turn that off? Why does https://demo.yubico.com/webauthn-technical/registration need a pin to register on Firefox?

Remove insecure rs1 flag

I think we should remove the insecure rs1 flag. This is currently disabled by default.

Currently insecure rs1 does NOT allow authenticator public keys that use SHA1. What the flag does is allow attestation CA's that sign with SHA1 to be used.

SHA1 is considered broken, and NIST now recommends against it's use. Most major CA's also are not allowed to use it.

Disabling this will only impact individuals using both attestation and authenticators that have a CA signed with SHA1. Since our current support around attestation is still evolving (though getting closer to something I'm happy with) I believe this will not have impacts on most users.

The risk of allowing the flag to continue is extended use of authenticators signed with CA's that are may potentially be able to have their attestations forged. Since the use of attestation is primarily for high-assurance environments, this is the kind of risk that should be considered by those deployments.

Fido MDS tool query
We need a way to be able to query the FIDO MDS data, but more specifically, users who use the tool need a way to query it as well.

How should we do this? What should the queries look like?

What kind of requirements would users realistically have?

Finally, when we have the query complete, what format should we output the data as? Something we can import directly into Webauthn-RS Attestation CA Lists?

Currently some ideas in my head for use cases are:

A user wants to allow device AAGUID X and Y and export these to an attestation CA List

A user wants to know what devices have been certified with "FIPS-CMVP-2"> X.

A user may want to know what devices support a specific extension such as hmac-secret.

A user wants to know what devices support a specific userverification method - or do not support a verification method (exclude bio metrics for example)

My thinking is that users will often query to find devices, shortlist them, then can just feed the aaguid list to extract the set of attestation's CA's in use (and the aaguids they govern).

Thoughts?

WIP: caBLE
~~This is still some way off, and needs #215.~~ This will be slow to implement because there's no publicly published spec, so I need to reverse engineer what Chromium does.

What's done:

generates a QR code

scans for BLE advertisement

decrypts BLE advertisement

connects to correct websocket

works on Android and current iOS

establishes a Cable-Noise channel (it's almost like Noise, but is different in enough ways to prevent using a standard Noise implementation, eg: it uses a non-standard DH function (P256))

decrypt the initial GetInfo response

Cable-Noise crypter channel (it again differs from Noise, by constructing nonces differently)

connected to CtapAuthenticator

added QR functionality to UiCallback

websocket tunnel works bidirectionally

encryption over websockets works

makecredential, getassertion works on current Android and iOS

encrypting discovery messages for BLE transmission works to other devices

establishing new tunnel on Google's tunnel server

implemented authenticator for Token (examples/cable_tunnel.rs): this allows you to tunnel a physical NFC or USB token over caBLE; this also works if you then re-use that authenticator on another transport (USB / NFC)

Note: this feature requires a Bluetooth Low Energy v4.2 HCI controller shared over a serial UART, because macOS + Windows don't let you send arbitrary Service Data adverts 💩

implemented QR code reading (unfortunately only seems to be about 80% reliable)

added AuthenticatorBackendHashedClientData API, which allows passing in client_data_json directly

wired up caBLE to that...

PIN/UV auth works 🎉

SoftToken partly works, it just needs a properly persisted private key

TODO:

put caBLE implementation behind a feature flag

untangle the protocol (in progress)

error propagation, rather than unwrap()

tests

documentation

using bluer (bluez rust bindings) for advertisements?

Deferred work:

Pairing / Linking / "Remember Device": Android always sends a linking information message, but the data is all null bytes if the user didn't consent... so this PR just ignores it.

DevicePubKey extension (Android only)

Using Apple's tunnel server

Fixes #

[ ] cargo fmt has been run

[ ] cargo test has been run and passes

[ ] documentation has been updated with relevant examples (if relevant)

example for rocket

Is your feature request related to a problem? Please describe. I am confused by how this would be integrated with rocket.rs, Its not like axum or tide in terms of architecture and is similar to flask.
