JS Key Chain

[richardschneider]

Implement a key store #2 in JavaScript. See the doc, code and spec

It must

• Manage a key (create, delete, list)
• Import/Export a key
• Encrypt/Decrypt a stream of data with a key
• Create a PKCS 7 CMS message

It could

• Sign/Verify a stream of data with a key

Is this going to adhere to what was already done for the golang implementation?

[richardschneider]

@RangerMauve Yes, the ipfs key commands will be implemented. Here's a more updated spec.

Also need ipfs key export and ipfs key import commands.

@RangerMauve Encrypted PubSub is easy with CMS. Simply convert the topic message (plain message) into CMS (cipher message) and then publish. The CMS message contains the information needed (the key id) to convert the cipher message into a plain message.

So the goal is to get IPFS to seamlessly integrate with rfc5652 messages for every level of the API?

[richardschneider]

@RangerMauve Yes, that is the goal. See the keystore spec for suggested API changes.

Thanks to a short discussion with @diasdavid, a few things have been clarified

• This a key chain
• It uses a key store to save/retrieve an encrypted key

The key store is some implementation of interface-datastore.

Note: 16 minutes of discussion equates to 5 hours of refactoring!

@richardschneider Could you maybe link to the discussion if there's a digital version available?
