What it can do
- Reconstruct header bytes
- Match known magic signatures
- Report likely MIME and extension information
How the recipe works
From Hex
Convert the displayed bytes into a binary value.
Detect File Type
Compare the leading bytes with known file signatures.

PNGWhen to use it
- File triage
- Forensics labs
- Checking mislabeled downloads
Adapt it
A signature identifies a likely container; parse or extract the file further before trusting its contents.

Adapted from University Politehnica of Bucharest: introductory security lab. The explanation and sample are written for Serialize, use synthetic or documentation-safe data, and are checked against the current operation catalogue. The workflow runs locally without an external API call.
