This commit simply renames two groups of internal status labels (called enums) in the Trezor firmware's cryptographic code. The old names like WAITING_FOR_REQUEST1 were shared between two different parts of the code, so the developer gave …
f1c74046by Ondřej Vejpustek+26−222 filesThis 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…
1b3128a4by Ondřej Vejpustek+20−92 filesThis commit fixes three places in the Trezor firmware's cryptographic code where a memory-clearing function could be called with a NULL pointer. In practice, passing NULL to memzero is harmless on Trezor's platform (it does nothing), but i…
0394e934by Ondřej Vejpustek+11−51 fileThis commit is a code cleanup (refactor) for the cryptographic handshake code used in Trezor devices. It changes how the other party's long-term public key is returned to the caller: instead of storing it inside an internal state structure…
3ead1aa6by Ondřej Vejpustek+79−423 filesThis 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.
33a119eeby Ondřej Vejpustek+15−151 fileThis commit adds a 135 millisecond delay during startup of the Tropic secure chip inside Trezor hardware wallets. The delay works around a bug where the chip briefly reports it is in 'maintenance mode' right after power-on, which causes an…
91046b78by Ondřej Vejpustek+17−01 fileThis commit updates Trezor's internal test-only files that simulate a TROPIC01 secure chip. It replaces old self-signed test certificates with a new four-level test certificate chain and embeds keys directly into config files instead of re…
e6e20071by Ondřej Vejpustek+560−21022 filesThis commit changes a Trezor firmware function so that, outside of a special factory testing mode (PRODTEST), it refuses to write an MCU attestation certificate. Previously the function accepted and stored such a certificate. The change pr…
6d2883bbby Ondřej Vejpustek+6−01 fileThis is a routine developer tooling change. Trezor replaced a shell script used to convert certificate files into C header files with a new Python script that does the same job. The actual certificate data did not change, only the wrapper …
92a5919aby Ondřej Vejpustek+436−35310 filesThis commit fixes how the Trezor Python library builds an authentication challenge. Previously, the code encoded the length of a header and the length of the challenge as a single byte, which only works for values up to 255. The fix uses a…
86b5d99cby Ondřej Vejpustek+3−31 fileThis is a minor code cleanup in the test suite. It replaces a manually constructed challenge message with a helper function that does the same thing. There is no change to the actual Trezor firmware or to how device authentication works in…
8e050722by Ondřej Vejpustek+10−71 fileThis commit updates test-only digital certificates used in Trezor firmware emulators for the T3W1 model. It does not change production device code. The certificates are part of the emulator's simulated secure chip environment and are not s…
360decd3by Ondřej Vejpustek+80−713 filesThis commit only moves existing test-only public keys from a test file into a shared internal module so they can be reused. It does not change any firmware behavior, add new keys, or alter any security logic. There is no apparent security …
5230821bby Ondřej Vejpustek+6−171 fileThis commit changes how Trezor hardware wallet firmware handles a special factory-testing mode called 'prodtest'. In prodtest builds, it now uses an empty placeholder certificate for MCU (microcontroller) attestation instead of a real devi…
ccb99c5eby Ondřej Vejpustek+11−11 fileThis commit is a code cleanup in the test suite. It merges two nearly identical certificate-verification routines into one shared helper and removes duplicated code. There is no change to the actual security checks performed, no change to …
c94d5dcbby Ondřej Vejpustek+30−531 fileThis commit simply moves a helper function called compact_size from one internal file to another and updates the import statements in files that use it. There is no change to what the function does, no bug fix, and no security impact.
2cb59ce6by Ondřej Vejpustek+29−296 filesThis commit only changes a test helper file in the Trezor firmware repository. It tightens how test code validates X.509 certificate chains by always checking the BasicConstraints extension and path length, rather than skipping the check w…
ce0e3b2fby Ondřej Vejpustek+6−101 fileThis commit changes only a test helper function in the Trezor firmware test suite. It moves a common-name check to the beginning of certificate-chain verification so the function can handle chains longer than before. There is no change to …
c3d46193by Ondřej Vejpustek+6−41 fileThis commit swaps in a new developer-debug-only public root key used to verify device certificates during factory testing. The old debug key is kept as a backup for compatibility. It is not a fix for a live user-facing vulnerability and do…
b55a7ca0by Ondřej Vejpustek+19−45 filesThis commit only adds a new automated test that checks whether Trezor hardware devices can prove their identity using an MCU-based digital signature. It does not change any firmware code that runs on the device, nor does it fix or introduc…
