How to validate .vf files in Python

Python

def is_vf(file_path: str) -> bool:
    """Check if file is a valid VF by magic bytes."""
    signature = bytes([0xF7, 0xCA])
    with open(file_path, "rb") as f:
        return f.read(2) == signature

How to validate .vf files in Node.js

Node.js

function isVF(buffer: Buffer): boolean {
  const signature = Buffer.from([0xF7, 0xCA]);
  return buffer.subarray(0, 2).equals(signature);
}

How to validate .vf files in Go

func IsVF(data []byte) bool {
    signature := []byte{0xF7, 0xCA}
    if len(data) < 2 {
        return false
    }
    return bytes.Equal(data[:2], signature)
}

Frequently Asked Questions

What is a .vf file?

A .vf file is a VF file.

What are the magic bytes for .vf files?

The magic bytes for VF files are F7 CA at byte offset 0. These bytes uniquely identify the file format regardless of the file extension.

How do I validate a .vf file?

To validate a .vf file, read the first bytes of the file and compare them against the known magic bytes (F7 CA) at offset 0. This is more reliable than checking the file extension alone, as extensions can be renamed.

What is the MIME type for .vf files?

The primary MIME type for .vf files is application/x-tex-virtual-font.

Is it safe to open .vf files?

VF (.vf) 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.
