Validation Code

How to validate .nitf files in Python

Python
def is_nitf(file_path: str) -> bool:
    """Check if file is a valid NITF by magic bytes."""
    signature = bytes([0x4E, 0x49, 0x54, 0x46, 0x30, 0x31, 0x2E, 0x31, 0x30])
    with open(file_path, "rb") as f:
        return f.read(9) == signature

How to validate .nitf files in Node.js

Node.js
function isNITF(buffer: Buffer): boolean {
  const signature = Buffer.from([0x4E, 0x49, 0x54, 0x46, 0x30, 0x31, 0x2E, 0x31, 0x30]);
  return buffer.subarray(0, 9).equals(signature);
}

How to validate .nitf files in Go

Go
func IsNITF(data []byte) bool {
    signature := []byte{0x4E, 0x49, 0x54, 0x46, 0x30, 0x31, 0x2E, 0x31, 0x30}
    if len(data) < 9 {
        return false
    }
    return bytes.Equal(data[:9], signature)
}

Frequently Asked Questions

What is a .nitf file?

A .nitf file is a NITF file.

What are the magic bytes for .nitf files?

The magic bytes for NITF files are 4E 49 54 46 30 31 2E 31 30 at byte offset 0. These bytes uniquely identify the file format regardless of the file extension.

How do I validate a .nitf file?

To validate a .nitf file, read the first bytes of the file and compare them against the known magic bytes (4E 49 54 46 30 31 2E 31 30) at offset 0. This is more reliable than checking the file extension alone, as extensions can be renamed.

What is the MIME type for .nitf files?

The primary MIME type for .nitf files is image/nitf.

Is it safe to open .nitf files?

NITF (.nitf) files are generally safe to open. They are classified as low risk because they primarily contain data rather than executable code. However, always ensure files come from a trusted source.
