### KeyChainManager / idStore 2.0 (maybe just in MetaMaskController)
|
|
keychains: []
|
|
getAllAccounts(cb)
|
|
getAllKeychainViewStates(cb) -> returns [ KeyChainViewState]
|
|
|
|
#### Old idStore external methods, for feature parity:
|
|
|
|
- init(configManager)
|
|
- setStore(ethStore)
|
|
- getState()
|
|
- getSelectedAddres()
|
|
- setSelectedAddress()
|
|
- createNewVault()
|
|
- recoverFromSeed()
|
|
- submitPassword()
|
|
- approveTransaction()
|
|
- cancelTransaction()
|
|
- addUnconfirmedMessage(msgParams, cb)
|
|
- signMessage()
|
|
- cancelMessage()
|
|
- setLocked()
|
|
- clearSeedWordCache()
|
|
- exportAccount()
|
|
- revealAccount()
|
|
- saveAccountLabel()
|
|
- tryPassword()
|
|
- recoverSeed()
|
|
- getNetwork()
|
|
|
|
##### Of those methods
|
|
|
|
Where they should end up:
|
|
|
|
##### MetaMaskController
|
|
|
|
- getNetwork()
|
|
|
|
##### KeyChainManager
|
|
|
|
- init(configManager)
|
|
- setStore(ethStore)
|
|
- getState() // Deprecate for unidirectional flow
|
|
- on('update', cb)
|
|
- createNewVault(password)
|
|
- getSelectedAddres()
|
|
- setSelectedAddress()
|
|
- submitPassword()
|
|
- tryPassword()
|
|
- approveTransaction()
|
|
- cancelTransaction()
|
|
- signMessage()
|
|
- cancelMessage()
|
|
- setLocked()
|
|
- exportAccount()
|
|
|
|
##### Bip44 KeyChain
|
|
|
|
- getState() // Deprecate for unidirectional flow
|
|
- on('update', cb)
|
|
|
|
If we adopt a ReactStore style unidirectional action dispatching data flow, these methods will be unified under a `dispatch` method, and rather than having a cb will emit an update to the UI:
|
|
|
|
- createNewKeyChain(entropy)
|
|
- recoverFromSeed()
|
|
- approveTransaction()
|
|
- signMessage()
|
|
- clearSeedWordCache()
|
|
- exportAccount()
|
|
- revealAccount()
|
|
- saveAccountLabel()
|
|
- recoverSeed()
|
|
|
|
Additional methods, new to this:
|
|
- serialize()
|
|
- Returns pojo with optional `secret` key whose contents will be encrypted with the users' password and salt when written to disk.
|
|
- The isolation of secrets is to preserve performance when decrypting user data.
|
|
- deserialize(pojo)
|
|
|
|
### KeyChain (ReduxStore?)
|
|
// attributes
|
|
@name
|
|
|
|
signTx(txParams, cb)
|
|
signMsg(msg, cb)
|
|
|
|
getAddressList(cb)
|
|
|
|
getViewState(cb) -> returns KeyChainViewState
|
|
|
|
serialize(cb) -> obj
|
|
deserialize(obj)
|
|
|
|
dispatch({ type: <str>, value: <pojo> })
|
|
|
|
|
|
### KeyChainViewState
|
|
// The serialized, renderable keychain data
|
|
accountList: [],
|
|
typeName: 'uPort',
|
|
iconAddress: 'uport.gif',
|
|
internal: {} // Subclass-defined metadata
|
|
|
|
### KeyChainReactComponent
|
|
// takes a KeyChainViewState
|
|
|
|
// Subclasses of this:
|
|
- KeyChainListItemComponent
|
|
- KeyChainInitComponent - Maybe part of the List Item
|
|
- KeyChainAccountHeaderComponent
|
|
- KeyChainConfirmationComponent
|
|
// Account list item, tx confirmation extra data (like a QR code),
|
|
// Maybe an options screen, init screen,
|
|
|
|
how to send actions?

},
|
|
methods: {

|
// arbitrary, internal
|
|
}
|

}

## A note on the security of arbitrary action dispatchers
|
|
|
|
Since keychains will be dispatching actions that are then passed through the background process to be routed, we should not trust or require them to include their own keychain ID as a prefix to their action, but we should tack it on ourselves, so that no action dispatched by a KeyChainComponent ever reaches any KeyChain other than its own.
