SeedSigner

This commit simply teaches the app to look for font files in two folders instead of one. It is a routine feature change to support translated or additional fonts, not a security fix or vulnerability.

This commit simply deletes five font files (for Arabic, Japanese, Korean, Simplified Chinese, and Thai text) from the project. There is no code change and no security-relevant behavior is modified. The action appears to be a cleanup or licensing/compliance step, not a fix for a vulnerability.

This commit adds user-configurable reminders to remove the microSD card from a SeedSigner hardware wallet. Previously the reminder stayed on screen essentially forever; now users can choose a 5-second toast, no reminder, or a blocking warning that requires removing the card. It is a usability and safety enhancement, not a fix for an exploitable vulnerability.

This commit is a minor cleanup and test-fix change. It replaces a debug logging line with a commented-out print statement and adds mock modules so the test suite can run without Raspberry Pi-specific hardware dependencies. There is no security-relevant change.

This commit is a performance optimization, not a security fix. It moves two slow-to-load software modules (numpy and pivideostream) so they start loading in the background while the user is still seeing the startup screen. This makes the device feel faster but does not change what the software does or how it protects data.

This commit simply changes the label on a button from 'Done' to 'Back to Main Menu' in a screen shown when an option is disabled. It is a cosmetic user-interface wording change with no security relevance.

This commit adds a friendly, specific error screen for when the SeedSigner device cannot talk to its camera. Previously, camera connection failures fell through to a generic 'unhandled exception' screen. The change reroutes that specific error to a new screen that tells the user to check the camera cable. It is a user-experience and diagnostic improvement, not a security fix.

This commit removes two redundant import statements inside a camera driver file. The same class (CameraConnectionError) is already available in the module, so the local imports were unnecessary. There is no security-relevant change.

This commit only changes the text on two on-screen buttons: one shown when an unrecognised QR code is scanned, and one shown after an unexpected system error. It does not change any security logic, input handling, cryptography, or network behaviour. It is a user-interface wording fix with no security relevance.

This commit changes how the SeedSigner camera code handles hardware camera failures. Instead of letting a low-level PiCamera error crash the user experience with a technical message, it now catches that error and raises a friendlier 'CameraConnectionError' telling the user to check camera connections. It is a reliability/usability improvement, not a security fix.

This commit changes how SeedSigner handles Bitcoin transaction files (PSBTs) that contain placeholder '00000000' fingerprints. Normally, a fingerprint identifies which wallet seed a transaction belongs to. Some wallet software exports incomplete data (xpub only, no derivation path), leaving zeros in the fingerprint field. Previously, SeedSigner could not recognize these transactions as belonging to the user's seed, showing a '?' and potentially refusing to sign. The new code tries to reconstruct the correct fingerprint by deriving public keys from the seed and comparing them. This is a usability fix, not a vulnerability patch, but it touches security-critical matching logic.

This commit fixes a localization bug in a Bitcoin seed backup verification feature. It prevents BIP-39 seed words (which must stay in English) from being translated into other languages when displayed as quiz answers. Previously, translating these words could confuse users or make backup verification fail. There is no direct security exploit here, but it removes a usability/reliability issue in a security-sensitive workflow.

This is a small internal cleanup change in a Bitcoin hardware wallet project. It replaces a manual flag used only during screenshot generation with an existing renderer property that already tells the code whether it is running in screenshot-generation mode. There is no user-facing or security-relevant change.

This commit is a small internal cleanup that changes how the screenshot test tool tells the splash screen to skip animations and delays. It replaces a parameter passed into the splash screen with a property checked on the renderer object. There is no security-relevant change for end users.

This commit only changes two button labels from title case to sentence case ("Discard Transaction" to "Discard transaction" and "Approve Transaction" to "Approve transaction"). It is a cosmetic text change with no security relevance.

This commit only renames user-facing text strings. Every occurrence of 'PSBT' shown to the user is changed to 'Transaction' or 'Proposed Transaction' (for example, 'Review PSBT' becomes 'Review Transaction'). There are no code logic, security, or behavior changes.

This commit is a simple code cleanup (refactor) in the SeedSigner project. It removes an unused intermediate screen that asked users to choose a BIP-85 'application mode' and instead takes them directly to choosing 12 or 24 words. The actual behavior for users remains the same because only one application mode (BIP-39 child seed) was ever supported. There is no security issue here.

This commit is a large merge of a test-only pull request titled 'exhaustive_psbtparser_tests'. The visible diff shows only new documentation, CI workflow, Docker, and project metadata files being added; no changes to the PSBTParser source code or runtime security logic are present in the supplied diff. It appears to be an initial repository population or a merge that brings in testing infrastructure and documentation rather than a security patch.
