A TUI application for inspecting CBOR (Concise Binary Object Representation) files, built with Rust and Ratatui. An online version is available here (a bit rough around the edges).
Pre-built binaries for Linux (.deb, .snap), Windows, and macOS (untested) are available in Releases.

By default, cbx assumes that the file contains a single CBOR sequence.
If your file contains multiple embedded CBOR sequences, press m to toggle Auto Mode. This uses simple heuristics to scan the file and identify potential CBOR sequences.
The scanning is not perfect but works pretty well for discovering complex nested structures.
If you have a good idea of where the target data is located in a large file (or the utility was able to find something, but borked the beginning), you can use z to zoom into the data, reinterpreting the data at the cursor as the beginning of a CBOR sequence.
