Validation Code

How to validate .he5 files in Python

Python
def is_he5(file_path: str) -> bool:
    """Check if file is a valid HE5 by magic bytes."""
    signature = bytes([0x0E, 0x03, 0x13, 0x01])
    with open(file_path, "rb") as f:
        return f.read(4) == signature

How to validate .he5 files in Node.js

Node.js
function isHE5(buffer: Buffer): boolean {
  const signature = Buffer.from([0x0E, 0x03, 0x13, 0x01]);
  return buffer.subarray(0, 4).equals(signature);
}

How to validate .he5 files in Go

Go
func IsHE5(data []byte) bool {
    signature := []byte{0x0E, 0x03, 0x13, 0x01}
    if len(data) < 4 {
        return false
    }
    return bytes.Equal(data[:4], signature)
}

Frequently Asked Questions

What is a .he5 file?

A .he5 file is a HE5 file.

What are the magic bytes for .he5 files?

The magic bytes for HE5 files are 0E 03 13 01 at byte offset 0. These bytes uniquely identify the file format regardless of the file extension.

How do I validate a .he5 file?

To validate a .he5 file, read the first bytes of the file and compare them against the known magic bytes (0E 03 13 01) at offset 0. This is more reliable than checking the file extension alone, as extensions can be renamed.

What is the MIME type for .he5 files?

The primary MIME type for .he5 files is application/x-hdf.

Is it safe to open .he5 files?

HE5 (.he5) 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.
