It was primarily used to track visited web addresses and related history data in AOL client applications, including companion typed-URL records. The format is generally safe and of historical interest only, as it is associated with older AOL software and is rarely encountered in modern systems.","mime":[],"risk_level":"Safe","signatures":[{"hex":"D4 2A","offset":0,"sources":[{"name":"Gary Kessler","url":"https://www.garykessler.net/library/file_sigs_GCK_latest.html"}]}],"related":["aut"],"usage":{"python":"def is_arl(file_path: str) -> bool:\n    \"\"\"Check if file is a valid ARL by magic bytes.\"\"\"\n    signature = bytes([0xD4, 0x2A])\n    with open(file_path, \"rb\") as f:\n        return f.read(2) == signature","node":"function isARL(buffer: Buffer): boolean {\n  const signature = Buffer.from([0xD4, 0x2A]);\n  return buffer.subarray(0, 2).equals(signature);\n}","go":"func IsARL(data []byte) bool {\n    signature := []byte{0xD4, 0x2A}\n    if len(data) < 2 {\n        return false\n    }\n    return bytes.Equal(data[:2], signature)\n}"}}}
