eth: allow EIP-712 message signing without anti-klepto

This commit adds an optional mode for signing Ethereum typed messages (EIP-712) that skips the anti-klepto protocol, falling back to normal deterministic signatures. The change is intentional and documented: some DeFi apps need signatures …

Feature adds a way to bypass anti-klepto for one signing pathBypass is opt-in by the host and version-gatedCore signing primitive now supports both anti-klepto and deterministic modes

build: enable -Wcast-align=strict

This commit turns on a stricter compiler warning that catches risky pointer casts in C code, and fixes the resulting warnings. The changes replace direct casts from byte buffers to larger types (like treating a raw byte array as a 32-bit n…

bitbox-secp256k1: remove needless ffi def of secp256k1_ecdsa_signature_serialize_compact

This commit removes a duplicate low-level binding to a secp256k1 cryptographic function and replaces its use with an equivalent, already-vetted wrapper from the project's dependency on the bitcoin::secp256k1 Rust crate. It is a code cleanu…

build: consolidate secp256k1 into new crate bitbox-secp256k1

This commit is a build-system refactor: it moves the secp256k1 cryptographic library dependency into a new Rust crate called bitbox-secp256k1 so it can be built with normal Cargo tooling instead of CMake. The actual cryptographic functions…

Refactor only: cryptographic code relocated, not modifiedBuild configuration constants preserved (ECMULT_WINDOW_SIZE=2, ECMULT_GEN_PREC_BITS=2, same module enables)No new unsafe blocks introduced beyond existing FFI bindings

port communication_mode to Rust

This commit rewrites a small piece of firmware logic from C to Rust. The logic decides whether the BitBox02 Nova hardware wallet should use Bluetooth or USB for communication. There is no obvious security bug introduced by the change; it a…

Language port of a communication-mode state machine from C to Rust with no apparent semantic change.Added unit tests for the ported logic.Removed C bindings and source files; added Rust `extern "C"` entry points for C callers.

license: replace Shift Apache headers

This commit is a bulk license-header cleanup. It replaces long, multi-line copyright and Apache-2.0 license notices at the top of 429 source files with a single, standardized machine-readable tag: 'SPDX-License-Identifier: Apache-2.0'. No …

rust: move secp256k1 funcs from keystore.rs to secp256k1.rs

This commit is a simple code reorganization: it moves functions that perform secp256k1 cryptographic signing from a file named keystore.rs into a file named secp256k1.rs. The actual behavior of the code, including how private keys are used…

add attestation_sign to securechip HAL

This commit is a straightforward internal refactoring: it moves the device attestation signing function behind a hardware-abstraction-layer (HAL) interface so the code can be more easily tested. The actual cryptographic operation and the d…

port test_memory_functional C tests to Rust

This commit is a routine refactoring that rewrites existing C unit tests in Rust. It does not change the actual firmware behavior or fix any security issue. One redundant test was removed, and several internal test-only helpers were added …

rust/hal: add Random to HAL

This commit is a routine code refactor, not a security fix. It moves the source of random numbers behind a new 'hardware abstraction layer' (HAL) interface so the same code can use a fake predictable random generator during automated tests…

Refactor only: production randomness still sourced from `bitbox02::random::random_32_bytes()`Schnorr auxiliary randomness (`aux_rand`) now injected via HAL traitTest-only deterministic random generator added (`TestingRandom`)
