The short version

What changed, and why it matters

This commit adds a new error code called Failure_InProgress to the Trezor firmware's communication protocol. It does not change any security logic; it simply gives the device a standardized way to tell a connected computer that a non-interruptible task is currently running. The actual behavior of blocking or allowing interruptions is not part of this change.

Recommended action

No security action required. Treat as a normal feature commit. Review the follow-up commits that actually emit Failure_InProgress to ensure non-interruptible workflows are enforced safely.

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.
