Account Store¶

Class Name	AccountStore
Implements	KeyStoreInterface
Extends	Logger
Extends	account-store.ts
Source	account-store.ts

The DApp Browser AccountStore is a adaption to the original blockchain-core AccountStore and overwrites the Keystore function, to handle private keys loaded from the lightwallet browser instance. Initially no keys are provided into the KeyProvider. When privateKeys are requested, the user must insert his password to unlock its lightwallet account to handle the privateKeys for signing.

The original DApp Browser AccountStore implements the KeyStoreInterface and is a wrapper for a storage, where evan.network account ids are stored. The default AccountStore takes an account –> private key mapping as a pojo as its arguments and uses this to perform lookups, when the getPrivateKey function is called. This lookup needs to be done, when transactions are signed by the InternalSigner (see Signer).

Note that the return value of the getPrivateKey function is a promise. This may not be required in the default DBCP AccountStore, but this allows you to implement own implementations of the KeyStoreInterface, which may enforce a more strict security behavior or are able to access other sources for private keys.
