Recovery keystore/wallet address storage and retrieval

[GuyPhy]

The recovery mechanism as laid out here relies on a secondary keystore/wallet address which the user can provide (or created by the app, if not given by user). This recovery pointer must be securely stored for retrieval in case of master keystore loss.

Discuss:

• What format the user input would be for secondary keystore
• Default flow to create a secondary keystore incase user does not have one
• Where will the secondary keystore be deployed
• Format in which the secondary credentials are stored and retrieval method for the same

[ManulParihar]

A keypair can be generated using one of the following methods:

• mnemonic: Can be provided as input string
• private key: Can be provided as input string
• keystore and password: The user should provide location to the JSON file along with keystore password

Another option to generate secondary keystore in app should be given. So the user can choose either to generate one in the app or import an existing one.
