The short version

What changed, and why it matters

This commit changes how COLDCARD displays and exports Bitcoin wallet descriptors and key expressions. It shows the descriptor/key expression on the device screen before exporting, and it now cryptographically signs key-expression exports when saved to SD card or virtual disk. The change is a user-experience and anti-tampering improvement, not a fix for an active security flaw.

Recommended action

No urgent action. Treat as a normal firmware improvement. Users may verify that exported descriptors/key expressions match the on-screen display and that key-expression files carry a valid signature when saved to removable media.

Security signals we found

01

Signed export now covers key expressions, reducing risk of undetected tampering during export

02

Descriptor/key expression shown on device screen before export improves user verification

03

Multisig key expressions explicitly use AF_CLASSIC for signing

04

No removal of cryptographic checks or access controls observed

05

No buffer, memory, or input-validation changes observed
