Ready Choose an operation

Base64, URL tools, JWT inspection, hashes, and file checksums are all available locally.

Compare

Verify hashes

Whitespace, colon separators, and case are normalized before comparison.

Trust Layer

Private by default

No server calls are needed for the tool’s core work.

Web Crypto SHA and HMAC

SHA-family hashes and HMACs use the browser’s Web Crypto API.

Compatibility MD5 included

MD5 is provided for legacy checksum comparison, not password storage or security decisions.

JWT Inspection only

JWT decoding shows readable header and payload data. It does not verify signatures.
