Information

How these utilities are meant to be used.

Base64: Binary-to-text encoding using 64 ASCII characters - common for embedding data in JSON, URLs, and email.

SHA-256: Produces a 256-bit digest for integrity checks and fingerprinting (not a replacement for password storage with proper KDFs).

Privacy: All work runs in your browser; input is not uploaded to Huntertech.
