# File integrity manifest generator

Hash a folder into a checksum manifest you can store, and later verify files against it with changed, missing, and not-in-manifest kept separate.

Drop files or a folder to start.

A manifest records what files looked like when you made it. It proves nothing about that moment by itself; store the manifest somewhere the files are not, or a changed file and its manifest change together. Hash files again after any legitimate edit, or the next check will call the file changed. SHA-256 and SHA-512 are the default choices. MD5 and SHA-1 catch accidents, not tampering. Everything runs in this tab; no file or digest is uploaded.
