Unable to get crypto working

I am building a crypto-enabled Matrix chatbot here: https://github.com/guardianproject/ractive/blob/master/bot.js

It currently works sans-crypto, but when I enable it, I can't decrypt any messages, and the client exits.

Any thoughts, insights, something I missed? Thanks!

@n8fr8, maybe you need to use a local storage replacement like @zhaytee needed in #816?

See https://github.com/zhaytee/matrix-rpc-js/blob/057492e55991f9f62480957d0a47aa571a9031ee/src/session.ts#L51 for example.

Ah I will take a look. I saw that, but wasn't sure what the different was in @zhaytee s storage implementation.

#437 seems to cover exactly what I am seeing

(n.b. that https://github.com/matrix-org/pantalaimon can be a very quick way of e2eifying bots)

After reading through matrix-recorder closely, I realized I need to do the following:

1. createClient() with minimal params
2. login() with user/pass and handle callback function
3. in callback, get response, and do a full createClient()

I also think, timing and order of operations mattered. After a lot of tinkering, I have a working bot client that can send/recv encrypted messages.

Here is the "working" commit:

This looks like it can be closed
