-# ID Refactor
-[Back to index](#index)
-
-## Goals
- - no way to get private key in javascript
- - ssb.c syncs/broadcasts/... efficiently for everybody
-
-## Schema
- - separate table to discourage leakage
- - `CREATE TABLE identities (user TEXT, public TEXT, secret TEXT);`
-
-## API
- - `ssb.createIdentity()` -> `id`
- - `ssb.getIdentities()` => `[id, ...]`
- - `ssb.deleteIdentity(id)`
- - `ssb.post(id, ...)`
- - `ssb.appendMessage(id, ...)`
