What CRC-24/OpenPGP Calculator does
Compute the OpenPGP CRC-24 variant using init 0xB704CE and polynomial 0x864CFB.
Input and output contract
A single local file up to 16 MiB is read. The algorithm is applied to the exact byte sequence with no text decoding. The exact fixed-width hexadecimal digest.
Important limitations
This is a raw checksum/hash calculation only. A matching value does not prove file validity, authenticity, or game compatibility.
Safety
This Phase 44 Tool runs locally in the browser with explicit input bounds. It does not infer game compatibility or repair unsupported formats.
