It is used for publishing manuals, reports, and other documents that require controlled access through compatible readers and authorization codes, including mobile viewing applications. The format is designed for rights management rather than open exchange; access is restricted by the publisher, and it is generally considered a legacy distribution method in some workflows.","mime":[],"risk_level":"Safe","signatures":[{"hex":"7B 44 52 4D 50 44 4B 7D","offset":0,"sources":[{"name":"Gary Kessler","url":"https://www.garykessler.net/library/file_sigs_GCK_latest.html"}]}],"related":["drmx"],"usage":{"python":"def is_drmz(file_path: str) -> bool:\n    \"\"\"Check if file is a valid DRMZ by magic bytes.\"\"\"\n    signature = bytes([0x7B, 0x44, 0x52, 0x4D, 0x50, 0x44, 0x4B, 0x7D])\n    with open(file_path, \"rb\") as f:\n        return f.read(8) == signature","node":"function isDRMZ(buffer: Buffer): boolean {\n  const signature = Buffer.from([0x7B, 0x44, 0x52, 0x4D, 0x50, 0x44, 0x4B, 0x7D]);\n  return buffer.subarray(0, 8).equals(signature);\n}","go":"func IsDRMZ(data []byte) bool {\n    signature := []byte{0x7B, 0x44, 0x52, 0x4D, 0x50, 0x44, 0x4B, 0x7D}\n    if len(data) < 8 {\n        return false\n    }\n    return bytes.Equal(data[:8], signature)\n}"}}}
