SecretStore: generating and retrieving decryption keys via service contract (#8029)
* SecretStore: started document keys generation via contract * fixed Cargo.lock * SecretStore: doc key contract gen tests * SecretStore: fixed log parsing * SecretStore: flush * SecretStore: secretstore_generateDocumentKey RPC * SecretStore: return encrypted_key from secretstore_generateDocumentKey * prepare to GenerateDocKey -> StoreDocKey * SecretStore: ability to identify requester via Public/Address * SecretStore: store author address instead of public in db * flush * SecretStore: flush * SecretStore: fixed test * SecretStore: flush * SecretStore: flush * SecretStore: flush * SecretStore: flush * SecretStore: start async generation session * SecretStore: process StoreDocumentKey service tasks * SecretStore: flush * SecretStore: update service contact ABI * SecretStore: flush * SecretStore: flush * SecretStore: fixed event * SecretStore: flush * SecretStore: fixed tests * SecretStore: fix broadcast shadows decryption * SecretStore: finally decryption via service contract works * SecretStore: fix for updated contract * SecretStore: restored pending requests reqding * SecretStore: fixed some TODOs * SecretStore: OnChainServiceContractAggregate * SecretStore: different names for different contracts types * SecretStore: updated contracts interfaces * SecretStore: utilize aggregate service contract * fixed compilation * SecretStore: fixes for updated contract * SecretStore: service fixes after testing * fixed cli test compilation * SecretStore: decryption_session_origin_is_known_to_all_initialized_nodes * SecretStore: added new contract listener tests * SecretStore: session_listener_works * removed optional TODO * SecretStore: fixed KeyServer shutdown * fixed warn + grumble * const durations
