The short version

What changed, and why it matters

This commit only adds new automated tests for the Trezor hardware wallet's Ethereum transaction signing. It checks that the device correctly rejects malformed transaction data sent during signing. There are no changes to the actual firmware code that users run, so this commit does not fix or introduce a security issue by itself.

Recommended action

No action required. This is a test-only commit. If reviewing a related security fix, examine the separate firmware commit that introduced the validation being tested.

Security signals we found

01

New negative tests for malformed Ethereum transaction calldata handling

02

Device is expected to reject oversized initial data chunk and oversized follow-up chunk

03

No firmware code changes; tests only

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.
