BibTeX is a bibliographic data management format created by Oren Patashnik and Leslie Lamport for the LaTeX document preparation system. It serves as a structured text database for organizing citation metadata, including authors, titles, and publication dates, within academic and scientific research. Although legacy in comparison to modern BibLaTeX extensions, this non-executable format remains a foundational standard in publishing and presents minimal security risks when processed by standard typesetting engines.

How to validate .bib files in Python

Python
def is_bib(file_path: str) -> bool:
    """Check if file is a valid BIB by magic bytes."""
    signature = bytes([0x25, 0x20, 0x42, 0x69, 0x62, 0x54, 0x65, 0x58, 0x20, 0x60])
    with open(file_path, "rb") as f:
        return f.read(10) == signature

How to validate .bib files in Node.js

Node.js
function isBIB(buffer: Buffer): boolean {
  const signature = Buffer.from([0x25, 0x20, 0x42, 0x69, 0x62, 0x54, 0x65, 0x58, 0x20, 0x60]);
  return buffer.subarray(0, 10).equals(signature);
}
Go
func IsBIB(data []byte) bool {
    signature := []byte{0x25, 0x20, 0x42, 0x69, 0x62, 0x54, 0x65, 0x58, 0x20, 0x60}
    if len(data) < 10 {
        return false
    }
    return bytes.Equal(data[:10], signature)
}
