## Frequently asked questions

### Can a magic number prove a file is safe?

No. It suggests a format but does not prove content is harmless or unchanged.

### When use CRC32 instead of a hash?

Use a published hash for identity verification; CRC32 detects many accidental errors but is not security evidence.

### Does high entropy prove encryption?

No. Compression and binary formats can also have high entropy; combine it with signature and provenance.
