A fast, modern web-based ASN.1 parser and editor — built with a strong focus on RPKI but fully compatible with any BER/DER/CER-encoded ASN.1 objects. Edit and encode ASN.1 objects without the need for complicated templates.
🔍 ASN.1 Object Parsing
Supports all major encoding rules: BER, DER, and CER — seamlessly decode any ASN.1 structure.
📝 Live Editing
Modify parsed objects in real time through the intuitive interface.
⚡ High Performance
Built for speed and efficiency, even with large and complex structures.
📦 RPKI Integration
- Embed ASN.1 objects into a fully valid RPKI repository structure for testing.
- Directly interact with RPKI relying parties (RPs) to validate your objects live.
🌐 Web-Based Interface
No installation required — accessible through your browser.
- Validate custom RPKI objects in a real-world RP context.
- Explore and debug arbitrary ASN.1 objects visually.
- Test how changes in encoded data affect structure and meaning.
- Quickly prototype and verify ASN.1 encodings for standards development.
- Frontend: vue.js
- Backend: Rust WASM
- Encoding/Parsing: cure_asn1 for parsing, cure_pp for nesting objects, cure_daemon for testing objects
