Why this tool stays in the browser

Hash a string locally for checksums, cache keys, and comparing blobs without sending the blob to a hash API. MD5 is available for legacy checksums — do not use it for passwords. bcrypt is a separate tool. JWT decoder is for tokens, not raw hashes.

FAQ

Is hashing done on the server?
No. SubtleCrypto / local algorithms run in the tab.
Should I hash passwords with SHA-256 here?
No. Use a password KDF such as bcrypt (see bcrypt Generator). These hashes are for checksums and fingerprints.
Which algorithms are included?
MD5 (legacy), SHA-1, SHA-256, and SHA-512.
