/**
 * Implementation of crypto strategies which should closely resemble a basic legacy behaviour of the crypto api in regard to user keys management
 * and server trust:
 * - Automatically creates a new key if there is no verified key available
 * - Fully trusts the public keys coming from the server for the creation of aes exchange keys to delegates
 * - Never trust the own public keys coming from the server: this way the sdk will not automatically create data for key recovery.
 *
 * Data owner delegation anonymity requirements instead are changed to require anonymous delegations for all data owners which are not hcps (instead
 * of never requiring anonymous delegations).
