Corel Paint Shop Pro image file magic bytes (.psp)

.psp file signature: 7E 42 4B 00 | application/octet-stream

Corel Paint Shop Pro image file is a raster graphics format created and maintained by Corel for its Paint Shop Pro image editor. It is used for editing and storing layered images, graphics projects, and intermediate artwork in the Paint Shop Pro workflow. The format is primarily associated with legacy desktop publishing and photo editing software; files from untrusted sources should be handled cautiously, as with any image format that may contain embedded data.

How to validate .psp files in Python

Python 
def is_psp(file_path: str) -> bool:
    """Check if file is a valid PSP by magic bytes."""
    signature = bytes([0x7E, 0x42, 0x4B, 0x00])
    with open(file_path, "rb") as f:
        return f.read(4) == signature

How to validate .psp files in Node.js

Node.js 
function isPSP(buffer: Buffer): boolean {
  const signature = Buffer.from([0x7E, 0x42, 0x4B, 0x00]);
  return buffer.subarray(0, 4).equals(signature);
}

How to validate .psp files in Go

Go 
func IsPSP(data []byte) bool {
    signature := []byte{0x7E, 0x42, 0x4B, 0x00}
    if len(data) < 4 {
        return false
    }
    return bytes.Equal(data[:4], signature)
}
