As long as you're generating a random password, there's probably not much of a point in passing to scrypt, as it can be used directly as an AES key.

Since the data to be written into the cipher is known to be just the provided plaintext, it'd be more direct to use cipher.update and cipher.final instead of bothering with stream callbacks.

Is it guaranteed that the ciphertexts of encrypt() or the AES cipher won't contain underscores or colons that would interfere with these splits?

are you still intending on working on this? having storepass work on oftc would be really nice! |

Fixes #1483, #747
Requires matrix-org/node-irc#110
Most of the work was already done in node-irc, so this just needs the bridge to store and pass through the certificate. I haven't yet implemented a way for users to pass the cert to the bridge. I am wary of passing it through the admin room directly as it would leave the cert in Matrix.
Perhaps we may have a HTTP submission page of some kind.
