Online Hash Calculator (SHA family)
A hash squeezes any input into a fixed-length, one-way digest, widely used to verify file integrity, store password digests, sign data and deduplicate. This tool outputs SHA-1 / SHA-256 / SHA-384 / SHA-512 at once.
Everything is computed locally with the browser-native SubtleCrypto; your input is never uploaded. Note: browsers don't expose MD5 natively (it's insecure and collision-prone), so this tool offers the stronger SHA family only.
