Intro

base64-js does basic base64 encoding/decoding in pure JS. Many browsers already have this functionality, but it is for text data, not all-purpose binary data.

Sometimes encoding/decoding binary data in the browser is useful, and that is what this module does.

API

base64-js has two exposed functions, toByteArray and fromByteArray, which both take a single argument.

• toByteArray- Takes a base64 string and returns a byte array
• fromByteArray- Takes a byte array and returns a base64 string
