webpack 5: ReferenceError: Buffer is not defined

[alerios]

Prerequisites

Current Behavior

When using did-jwt with webpack 5, the following error shows up: "ReferenceError: Buffer is not defined", since Buffer is not included in the browser.

Failure Information

There are several references to the use of "Buffer.from" in the did-jwt code: https://github.com/decentralized-identity/did-jwt/search?q=%22Buffer.from%22

Alternatives you considered

Based on what I could find, these could be replaced to use "u8a.fromString" instead for better compatibility.

In the meantime I applied a polyfill using this guide, which cleared the issue: https://viglucci.io/how-to-polyfill-buffer-with-webpack-5
