Direct In-Browser PCAP Packet Decoding
Inspecting packet capture (.pcap) files traditionally requires desktop installations of Wireshark or tcpdump. This tool utilizes browser ArrayBuffer and DataView binary parsers to decode link-layer and transport-layer frames directly in WebAssembly-accelerated memory.
Supported Network Protocols
- Ethernet II: Resolves 48-bit source and destination MAC addresses and EtherType markers.
- Internet Protocol (IPv4): Decodes packet headers, TTL hop counters, and transport identifiers.
- TCP & UDP: Analyzes 3-way handshake flags (SYN, ACK, FIN, RST), sequence numbering, and application ports.
- Application Payloads: Extracts DNS questions and plaintext HTTP request headers.
Frequently asked questions
Can this tool inspect giant capture files?
It is optimized for capture files under 20MB. Because decoding happens in browser volatile memory, zero packet data is uploaded to remote servers.
Does it support pcapng?
Standard PCAP microsecond and nanosecond captures are supported natively.
