feat(core/rust): separate trezor-crypto to its own Rust crate

This commit is a large but straightforward internal refactoring: the cryptographic code is moved from one Rust crate (`rtl`) into a new dedicated crate (`crypto`), and all project dependencies are updated to point to the new crate. The act…

refactor(core/embed): reorganize error handling

This commit is a code cleanup that moves how Trezor firmware handles fatal errors and shutdowns between its internal software layers. It does not add new user-facing features or change security protections. The main risk is that reorganizi…

This is a purely cosmetic code-style commit. It runs the project's Rust formatter across hundreds of files, changing only how import statements are grouped and how long comments are wrapped. No program logic, security behavior, or function…

build(core): avoid unused variable warning in rng_fill_buffer_strong

This is a minor build cleanup. A developer added a compile-time branch so that when neither the Optiga nor Tropic security chips are used, the 'strong' random-number wrapper simply calls the normal random-number function and returns. The o…

feat(python): client.ensure_unlocked() works without deriving a session

This is a small optimization in the Trezor Python library. The `ensure_unlocked()` helper used to pick or create a wallet session, which forced the hardware wallet to derive the master seed just to check if the device was unlocked. The new…

fix(python): fix trezorctl get-session

This commit fixes the `trezorctl get-session` command in Trezor's Python library. It prevents crashes when an invalid session ID is supplied, ensures a required pairing step is completed when resuming secure (THP) sessions, and changes the…

Invalid input (malformed base64 session ID) previously caused an unhandled exception/crash in the CLI.THP session resumption could leave pairing in an invalid state because `pairing.finish()` was skipped when no pairing flow ran.The `passphrase=False` semantic change could affect which wallet/session is derived in CLI workflows, but the commit message frames this as matching actual intended usage.

refactor(python/trezorctl): respect prompt_passphrase when creating a new session

build: prevent uv from using packages newer than 30 days

This commit is a hardening change to Trezor's build tooling. It tells the Python package manager 'uv' not to use any package uploaded to PyPI in the last 30 days, which reduces the risk of accidentally pulling in a freshly compromised depe…

fix(python): do not warn about session id when in bootloader mode

This is a tiny fix in the Trezor Python library that stops an incorrect error message. When a Trezor device is in bootloader mode, it legitimately does not return a session ID, but the library was wrongly logging a scary 'session managemen…

This commit fixes a logic bug in the Trezor Python library's pairing flow. Previously, the library would skip pairing whenever the device allowed it, even when the caller also asked for a security credential. Skipping pairing moves the pro…
