feat(cardano): Show path, address params and longer payload chunk

This commit improves the Cardano message-signing feature on Trezor hardware wallets by showing users more details on the device screen before signing. It displays the signing path, the address parameters (if provided), and a larger chunk o…

feat(cardano): stop hashing in message signing

This commit removes the option to sign a hash of a Cardano message instead of the message itself. The device now always signs the actual message payload directly, up to a size limit. This is a feature/API change rather than a fix for an ac…

Removed hash-then-sign mode for Cardano message signingFirmware now signs raw message payload instead of a hashPayload size capped at MAX_CHUNK_SIZE and only one chunk accepted

fix(cardano): Change display_ascii flag to prefer_hex_display

This commit renames and slightly changes a Cardano message-signing display option. Previously, the host had to explicitly request ASCII display, and the device would reject payloads that were not clean, readable ASCII. Now the host can ask…

UI display-mode flag renamed and semantics invertedPrevious hard error on non-unambiguous ASCII removed; behavior now falls back to hex displayNo cryptographic, parsing, or authorization bypass changes observed
