Show HN: Recursively detects and decodes multiple formats in nested data

2 points by ngzhixiao a day ago

I built an auto-decoder library that can:

1. Automatically detect and decode various formats (URL, Base64, JWT, QueryString, etc.) 2. Recursively parse nested encodings (e.g. URL with Base64 parameters containing JSON) 3. Handle ambiguous inputs by providing multiple decode possibilities with confidence scores 4. Preserve the decode path for nested structures

For example, it can parse: - URLs containing Base64-encoded JSON parameters - Query strings with JWT tokens that contain nested Base64 values - JSON objects with multiple encoded fields
