Bugfix: Invalid Krux Encrypted Mnemonic Used as Passphrase Raised No Error

This release includes a hotfix that improves error handling when decrypted data is invalid for the current context.
In the Passphrases context, validation is now stricter and scanned data must consist only of ASCII text.

This change resolves edge cases where invalid inputs, such as binary data from an encrypted mnemonic QR code, were previously accepted without a clear error. The device will now properly notify you when the input is not valid text.

Note for users with non-ASCII passphrases:
If you use a QR code generated outside Krux that contains non-ASCII characters (e.g., ç, ã, é, Б, Г, Д) as a passphrase, move your funds to a new wallet using your current firmware before updating.

After updating, only standard ASCII passphrases (those available via the Krux keypads) can be used when creating new wallets.

This release introduces support for the TZT device and adds a mnemonic XOR function increasing key creation and backup options. Under the hood, substantial code optimizations reduce firmware size and RAM usage, while improved SD card compatibility ensures better reliability. Please note that support for the Maix Bit device has been officially discontinued.

Changes

New Device Support: TZT

The TZT CanMV is similar to the WonderMV but includes five buttons and a premium milled aluminum housing. Computer simulator for the TZT device is also included.

Mnemonic XOR

Krux can now apply XOR operations on entropy bytes between a loaded mnemonic and another chosen one, similar to Coinkite's SeedXOR protocol.

Code Optimization

Reduced firmware size by 25% and lowered RAM usage through code cleanup and optimizations.

Increased SD Card Compatibility

Krux can now recognize and work with a wider range of SD cards that were previously unsupported.

Discontinued Support for Maix Bit Device

The Maix Bit device has long been discouraged due to its poor-quality camera. Starting with this release, we are discontinuing support and it will no longer be included in future builds. The support and parameters for building its firmware from source, however, will be kept.

This release includes a fix for a recently discovered issue #477 in our encryption system. Due to an implementation error, the camera-captured entropy was not being used as intended in our AES-CBC encryption mode. This means that the additional layer of security provided by the camera's randomness was not effectively applied.

What Does This Mean for You?

Who is Affected: Users who have changed their settings to use AES-CBC encryption instead of the default AES-ECB for encrypted backups on flash storage, SD cards, or encrypted QR codes.

Impact: The encryption strength for these backups may not be as robust as intended.

Recommended Action:

If you have used AES-CBC encryption for your backups, we recommend the following steps:

1. Update Your Device: Please install the latest software update where this issue has been resolved.

2. Replace Your Backups: After updating, recreate your encrypted backups on flash storage, SD cards, or QR codes to ensure they are secured with the corrected encryption implementation.

Thanks @earthdiver for the finding!
Thanks @jdlcdl, @3rdIteration and @qlrd for helping on the issue evaluation and solution!

Always test your encrypted backups and keys after creation and have a redundant physical backup of your keys.

This release contains a new experimental tamper detection tool, Japanese Translation and other reliability improvements. Here's an in-depth review of the key updates:

Changes

Tamper Check Flash Hash and Tamper Check Code (Experimental)

The Tamper Check Flash Hash (TC Flash Hash) feature verifies the integrity of the device's flash memory by generating a unique tamper indicator that relies on hash properties. After setting up a Tamper Check Code (TC Code), this check can be performed at every boot or manually via Tools -> Flash Tools. The TC Code is a key component, required to execute the verification and detect unauthorized changes to the device's memory. Users can also fill unused memory blocks with camera-generated entropy to further mitigate tampering attempts.

Flash Map

Flash Map is an auxiliary tool that allows users to visualize the regions of the device's memory that are empty. This helps users verify the results of actions such as:

• Wiping the device's memory
• Erasing the user's area
• Saving settings and encrypted mnemonics
• Filling empty blocks with camera-generated entropy

Japanese Translation

Japanese translation has been added.

BIP85: Allow Export Base64 Passwords

In addition to BIP39 Mnemonics, users can now derive Base64 passwords from their keys. These passwords, which can be used in standard logins, can be noted down, saved to an SD card, or exported as a QR code.

Vulnerability Fix: Block Import of Python Modules from SD Card

A feature of MicroPython, commonly used for general-purpose development, is the ability to run Python code directly from an SD card. However, with the recent implementation of tamper detection tools, this behavior is now considered a vulnerability. It was discovered that MicroPython would prioritize importing .mpy (Python frozen modules) from an SD card before checking the internal flash, which could be exploited to run unintended code from the SD card. To address this, a block has been implemented in MicroPython to prevent running any code from the SD card, enhancing the overall security of the device.

Add Compatibility to Partial Text Mnemonic QR Codes

Partial Text Mnemonic QR Codes, like Coldcard's backups, where mnemonics words are cropped and contain only the first 3 or 4 letters, are now auto-completed and loaded.

Multi-keypad Position Indicator

An indicator has been added to the bottom of keypads to help users identify the keypad index while swiping between them.

WonderMV Simulator

Computer simulator for WonderMV device has been added.

Krux Ethos

Guidelines have been created to assist with decision-making regarding the Krux project's interactions with contributors, users, and businesses that may create products or services related to Krux.

Minor Bugfixes and Refactors

Several code improvements for better reliability and efficiency.

Added Support for East Asian Languages - Korean and Simplified Chinese

After implementing low-level support for different glyph form factors, we were finally able to introduce the long-awaited Korean language translation. Simplified Chinese support followed shortly thereafter.

Faster PSBT Scanning

Reduced the time required to scan larger PSBTs by optimizing processing speed.

Improved QR Code Scanning

Enhanced scan success rates in challenging conditions, such as reduced focus or scanning from greater distances.

UI Standardization

The positions of "Yes" and "No" in prompts have been inverted to standardize the UI. Affirmative actions, such as "Yes," "Go," and "Proceed," will now be positioned on the right, while "No," "Esc," and "Back" will be on the left.

Enhanced Scanning Progress Bars

QR code progress bars now provide more detailed information. For UR PSBTs, the progress bar indicates when a valid frame is captured, while for BBQR, it displays the index or position of the last successfully scanned frame.

Mnemonics Editor - Loading Mnemonics

When manually loading an existing mnemonic, you can now correct typos and mistakes during the review stage by simply tapping or navigating to the incorrect words. The checksum word will be highlighted in red if the entered mnemonic is invalid to help detect eventual problems.

Mnemonics Editor - New Mnemonic

When generating new mnemonics through dice rolls or camera images, you can now modify the entropy by changing some of the mnemonic words. The final word will dynamically adjust to always produce a valid checksum.

Support for Scanning Various Binary Grid Formats

In addition to TinySeed, the camera can now scan and load mnemonics from equivalent formats, such as OneKey KeyTag, or even generic binary grids, like spreadsheets with colored, squared cells.

Message Signing Using SD cards

Recently released in Sparrow, the SD card message signing workflow is now supported.

Generate Double Mnemonics from Camera

When generating a new mnemonic using the camera, users can now choose to create a "Double Mnemonic," in addition to the standard 12 and 24-word options. This feature generates a 24-word mnemonic that, when split in half, forms two valid 12-word mnemonics.

Increased Valid Touch Surface

To improve touch accuracy, especially on small touchscreens, the touch surface area of buttons has been increased to make better use of the available screen space.

Add Account Descriptor Type Support

Krux now accepts urtype.Account type QR code descriptors.

Option on tools to wipe the device, permanently removing settings and stored encrypted mnemonics by erasing every single bit of user's flash space.

Better Deletion of Mnemonics Stored on SD card

When deleting an encrypted mnemonic from an SD card, Krux will now overwrite the memory area making it impossible to recover the previously stored data.

Save and Load Wallet Output Descriptor from SD card

Create or load from a wallet output descriptor file on an SD card. The backup file format is compatible with most coordinators.

Sign Messages at a Derived Bitcoin address

Sign messages from Sparrow and Specter, via QR code, also attesting a Bitcoin address belongs to you.

Reproducible Builds

To enhance the reproducibility of firmware builds, random variables such as file write timestamps have been removed from the build process. As a result, builds from developers' computers, those built within GitHub Actions from published code, and those you compile locally are more likely to be identical and have the same hash checksum as the official and beta releases. This change ensures greater consistency and traceability across all builds.

Add Entropy Quality Estimation for Mnemonic Creation.

Entropy quality estimators, like Shannon's entropy, were added to mnemonic generation through dice rolls and camera snapshot.

IRQ Interfaces
