The short version

What changed, and why it matters

This commit adds a numeric model identifier for a specific Trezor hardware board (the T3W1 revision A with Nordic nRF52832 chip) into the firmware signing process as a protected custom TLV field. It is a feature addition that embeds device-model metadata into signed firmware images. There is no indication in the commit that it fixes a security bug or introduces a vulnerability.

Recommended action

No security action required. Treat as a normal firmware feature commit. If reviewing broader firmware signing design, verify that the new protected TLV is validated by the bootloader and that the model identifier cannot be reused across incompatible hardware revisions.

Security signals we found

No strong security signals were identified.

This commit removes the SHA-1 hashing function from the regular Trezor firmware. SHA-1 is an old, weak hash algorithm that is no longer considered secure for sensitive uses. The change deletes the code that exposes SHA-1 to apps running on…

refactor(crypto): pass static public key to `noise_xxpsk3_*_init()`

This commit changes how a cryptographic library sets up secure connections. Previously, the code automatically calculated the public key from the private key. Now, the caller must provide the public key directly. This is a code-quality ref…

refactor(crypto): change order of parameters

This commit simply reorders the arguments of an internal function called dh() and updates every place that calls it. The actual math and security behavior are unchanged; it is a code cleanup with no security effect.
