Keyring Subdomain
The KeyringSubdomain is where the private keys for the profiles are stored. The keys are encrypted and secured using a user-provided password before being stored.
The KeyringSubdomain allows for creation of new private keys, returning the Ethereum-based address associated with that key.
It allows for creating, unlocking, and locking of the keyring using a user-provided password.
It handles the signing of data, messages, and transactions using a private key.
The private keys can not leave the KeyringSubdomain unless the user chooses to reveal it for a specific address or exports the private keys in an encrypted format for use in a backup file.
