Why it exists
TLV Walker was built to make Tag-Length-Value encoded data easier to inspect during binary analysis and protocol exploration. Instead of manually stepping through bytes, the user can navigate a tree representation of the parsed structure.
Project media
Architecture
- The application opens TLV-encoded files in binary mode.
- Parsed tags are displayed as a hierarchical tree.
- Users can configure whether tags are treated as directories or leaves.
- Tag decoding schemas can be imported and exported as JSON.
- Selected values are previewed in hexadecimal and text form.
Key features
- Tree visualization for nested TLV data.
- Hex and text previews.
- Schema import/export.
- Expandable and collapsible nodes.
- Windows Forms desktop interface.
Design decisions
The tool is intentionally visual: binary formats become easier to reason about when structure, nesting and value previews are shown together.
