Why this matters
Base64 and hash functions appear in almost every developer workflow: encoding binary data for transport, verifying file integrity, testing password hashing behavior, or debugging an API that sends encoded payloads. Having encode, decode, and multiple hash algorithms in one browser-side tool means you can work through an entire encoding or verification chain without opening a terminal, installing a package, or sending your data to a remote service. The HMAC mode is especially useful when you need to verify a webhook signature or reproduce a signed request without a full development environment.
