It is used to store and share files protected with password-based encryption on desktop and server systems, with support in common archive and encryption workflows. The format is designed for confidentiality, but security depends on strong passwords and careful handling of encrypted files; older files may use earlier version variants.","mime":[],"risk_level":"Safe","signatures":[{"hex":"41 45 53","offset":0,"sources":[{"name":"Gary Kessler","url":"https://www.garykessler.net/library/file_sigs_GCK_latest.html"}]}],"related":[],"usage":{"python":"def is_aes(file_path: str) -> bool:\n    \"\"\"Check if file is a valid AES by magic bytes.\"\"\"\n    signature = bytes([0x41, 0x45, 0x53])\n    with open(file_path, \"rb\") as f:\n        return f.read(3) == signature","node":"function isAES(buffer: Buffer): boolean {\n  const signature = Buffer.from([0x41, 0x45, 0x53]);\n  return buffer.subarray(0, 3).equals(signature);\n}","go":"func IsAES(data []byte) bool {\n    signature := []byte{0x41, 0x45, 0x53}\n    if len(data) < 3 {\n        return false\n    }\n    return bytes.Equal(data[:3], signature)\n}"}}}
