Changes from testing and review This CL syncs the AOSP version of the code in common/ with the current main branch of the development repo, skipping any code that relies on new dependencies being imported. Major changes: - encode curve type (Nist, EdDsa, Xdh) in serialized EC keys - split Ed25519 keys from X25519 keys from NIST keys - move ckdf/hkdf into traits with default impls for AesCmac / Hmac - commonize operation traits - tweak error behaviour to match what VTS tests expect - add message for setting attestation ID info (but only if there is no trait impl provided for retrieving attestation IDs for the device) - Tag::UsageCountLimit is a special case - enforced at different levels depending on value and secure storage availability Test: m libkmr_common Bug: 195310053 Change-Id: I62c9e6583ef2b1f0d43c8030dea550e85d4dede8
This repo holds work in progress for a Rust implementation of Android's KeyMint HAL.
The codebase is divided as follows. Only the crates in bold are expected to be used in Android; the remainder are conveniences to allow development outside of Android.
| Subdir | Crate Name | std? | Description |
|---|---|---|---|
derive | kmr-derive | Yes (build-only) | Proc macros for deriving the AsCborValue trait |
common | kmr-common | No | Common code used throughout KeyMint/Rust |
hal | kmr-hal | Yes | HAL service implementation |
boringssl | kmr-boringssl | Yes | Boring/OpenSSL-based implementations of crypto traits |
tests | kmr-tests | Tests and test infrastructure | |
ta | kmr-ta | No | TA implementation |
ta-main | kmr-ta | Yes | TA implementation using TCP |
