- `compiled_app_binaries` within binary files of the build process for each device
- `code-coverage` within HTML details of code coverage
## Known limitations
Today, the current App has some known limitations.
- RSA4096 is disabled, because of an issue with the watchdog, resetting the device
during long prime number operation.
- Using Ed25519 template, the decrypt doesn't output a correct result.
