Encoders & Crypto

Encode, decode, hash

Encode and decode the formats that carry data through text-only channels: Base64, URL percent-encoding, HTML entities, raw binary, and JSON or string escaping, plus a JWT decoder for inspecting tokens. These run entirely client-side, which is the point when the thing you are decoding is an access token, an API key, or a basic-auth header.
