The short version

What changed, and why it matters

This commit replaces two binary firmware files for the Trezor T3W1 hardware wallet's security monitor (secmon) with newer versions built from secmon v1.0.5. The actual code changes are not visible because the files are binary blobs. There is no claim in the commit message that this fixes a security vulnerability, and no independent references were provided. On its own, this looks like a routine component update.

Recommended action

No immediate action is indicated by this commit alone. If reviewing for security, obtain the secmon v1.0.5 source or release notes and compare against the prior version to determine whether the update addresses any security issues.

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.
