{"success":true,"data":{"ext":"tr1","name":"Novell LANalyzer capture file","description":"Novell LANalyzer capture file is a legacy network packet capture format created and used by Novell for its LANalyzer analysis tools. It was used to record traffic for troubleshooting, protocol inspection, and performance analysis on local area networks, and the files could be reviewed in compatible network diagnostics software. The format is largely obsolete today and is generally considered safe, though historical capture files should still be handled cautiously when opened in older or unsupported tools.","mime":[],"risk_level":"Safe","signatures":[{"hex":"01 10","offset":0,"sources":[{"name":"Gary Kessler","url":"https://www.garykessler.net/library/file_sigs_GCK_latest.html"}]}],"related":[],"usage":{"python":"def is_tr1(file_path: str) -> bool:\n    \"\"\"Check if file is a valid TR1 by magic bytes.\"\"\"\n    signature = bytes([0x01, 0x10])\n    with open(file_path, \"rb\") as f:\n        return f.read(2) == signature","node":"function isTR1(buffer: Buffer): boolean {\n  const signature = Buffer.from([0x01, 0x10]);\n  return buffer.subarray(0, 2).equals(signature);\n}","go":"func IsTR1(data []byte) bool {\n    signature := []byte{0x01, 0x10}\n    if len(data) < 2 {\n        return false\n    }\n    return bytes.Equal(data[:2], signature)\n}"}}}
