Here’s a code snippet translating a base64-encoded string to UTF8: // using the base64 encoded string from aboveĬonst plain = om('dXNlcm5hbWU6cGFzc3dvcmQ=', 'base64'). You can then translate the encoding to a UTF8 representation. Make sure to pass the correct encoding to initialize the buffer correctly. Pass it your base64-encoded string as the first argument and the base64 encoding as the second argument. There are a lot of places where base64url encoding / decoding are already. So, plus to minus, and the forward slash 'lies down' to become an underscore. Namely, a '+' is replaced with a '-' and a '/' is replaced with a ''. Again, create a buffer instance using the om method. The alternative Base64 encoding called Base64url simply replaces those 2 troublesome characters with two safe characters. Here’s a code snippet translating a string in UTF8 encoding to base64: const encoded = om('username:password', 'utf8').toString('base64')ĭecoding a base64-encoded string is also possible using the global Buffer class. Pass the value you want to base64-encode as the first argument and the current encoding as the second argument. You can create a buffer instance using the om method. Node.js supports data encoding via the global Buffer class. Retrieve the List of Supported Hash Algorithms Notice that Heroku is encoding a buffer thats one byte shorter (missing the final letter a ).

Buffers can be implemented using ArrayBuffer. It supports URL-safe encoding and enabling/disabling padding. Recommended to explicitly reference it via an import or require statement. Base64 for both node.js and browser JavaScript. While the Buffer class is available within the global scope, it is still Plain Uint8Arrays wherever Buffers are supported as well. The Buffer class is a subclass of JavaScript's Uint8Array class andĮxtends it with methods that cover additional use cases.
