How to decode a base64 encoded delegation

[jamiechicago312]

Our users have asked about how to produce a valid base64-encoded delegation string. Our CLI tool will encode the delegation as a "multibase" base64 string - to get the raw base64 string you can drop the leading m from the string, which should make it compatible with tools like atob in JavaScript.

If you are simply trying to figure out how to import one of the multibase strings our CLI has produced, you may find it easier to use our JavaScript parsing tool, like this:

Use parse from @web3-storage/w3up-client/proof to turn the base64 encoded delegation back into a delegation in JS.

e.g.

import { parse } from '@web3-storage/w3up-client/proof'

const delegation = await parse('mAYIEAJQE...')
