The short version

What changed, and why it matters

This commit changes a build configuration for Trezor's Unix emulator so that MicroPython uses the standard C setjmp/longjmp mechanism for non-local returns instead of a custom x86_64 assembly implementation. There is no direct security fix here; it is a portability/refactoring change. It does not affect the actual Trezor hardware firmware.

Recommended action

No security action required. Treat as a normal refactoring commit. If auditing, verify that the setjmp-based NLR behaves correctly in the emulator test environment, but this is not a security-relevant change.

Security signals we found

No strong security signals were identified.

chore(core): remove sha1 from regular FW

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…

Cryptographic key handling changed: public key is now supplied rather than derivedPotential reduction of key-mismatch risk if caller provides correct public keyNew null-pointer check added for static_public_key

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.
