First define your component:

• value types and defaults for each key
• 'channels', actions that potentially modify state or perform i/o. triggered by button presses, mouse movements, etc

var Value = require('observ')
var Component = require('../lib/component.js')
var Wallet = require('../wallet/index.js')
var Identity = require('../identity/index.js')
var render = require('./render.js')

nm = NumberMachine()

nm.multiply(2)
nm.add(6)
nm.subtract(3)
nm.multiply(2)

nm(10)  //=> 46
nm(0)  //=> 6
nm(20)  //=> 86

10:46 <kumavis> maybe components could have some generic channel-generating hooks ?
10:46 <kumavis>  render() { return inputBox( state.label, state.channels.bindValue('label') ) }
10:47 <kumavis> which could simplify to inputBox( state, 'label' )
10:47 <kumavis> so i dont have to create a channel that only updates a value directly passed in
10:48 <kumavis> right now i have to do inputBox(state.newIdentityAddress, state.channels.updateNewIdentityAddress)
10:48 <kumavis> function updateNewIdentityAddress(state, data) {
10:48 <kumavis>   state.newIdentityAddress.set(data.text)
10:48 <kumavis> }
10:48 <kumavis> its just a lot of code to do one simple thing i feel

start (secret) -> return apiObject with [encrypt, decrypt] with plaintext secret stored in closure

encrypt (input) -> generate salt, iv, additionalData, -> generate hash from salt and secret -> generate key from hash -> encrypt with key -> return json string with salt, iv, additionalData, and encrypted data (edited)

decrypt(input) -> read salt, iv, additionalData -> generate hash from salt and secret -> generate key from hash -> decrypt with key -> return unecrypted data

and the 'encrypted text' includes plaintext metadata about the encryption settings (salt, iv, additionalData)
