Interface PCKeysProcessor

All Known Implementing Classes:

PCRegularKeysProcessor

public interface PCKeysProcessor

This interface defines functionality which should be implemented by some class which purpose is to manage the process of key pair generation and transaction processing.
The default implementation, PCRegularKeysProcessor, generates key pair in Android KeyStore and uses it to process transactions.
Another example of implementation of this interface is PCRutokenKeysProcessor class defined in an additional module which can be embedded in an app with PC SDK to support Rutoken smart cards for generation and usage of asymmetric keys.

Method Summary

Modifier and Type	Method and Description
void	getPublicKey(PCUser user, PCGetPublicKeyCallback callback) Generates a key pair (or reuses an existing one if this is applicable to a particular case) and returns a public key via the callback.
void	process(PCUser user, java.util.List<PCTransaction> transactionsToConfirm, java.util.List<PCTransaction> transactionsToDecline, PCMultipleProcessingCallback callback) Processes a set of transactions.
void	renew(PCUser user, PCTransaction transaction, java.lang.String externalAlias, PCRenewRequestCallback callback) Performs key renewal

Method Detail

getPublicKey

void getPublicKey(PCUser user,
                  PCGetPublicKeyCallback callback)

Generates a key pair (or reuses an existing one if this is applicable to a particular case) and returns a public key via the callback.

Parameters:

user - Target PCUser

callback - Callback to handle results

process

void process(PCUser user,
             java.util.List<PCTransaction> transactionsToConfirm,
             java.util.List<PCTransaction> transactionsToDecline,
             PCMultipleProcessingCallback callback)

Processes a set of transactions.

Parameters:

user - Target user

transactionsToConfirm - List of transactions which should be confirmed

transactionsToDecline - List of transactions which should be declined

callback - Callback to handle results

renew

void renew(PCUser user,
           PCTransaction transaction,
           java.lang.String externalAlias,
           PCRenewRequestCallback callback)

Performs key renewal

Parameters:

user - Target user whose keys are to be renewed

transaction - Pseudo-transaction for which HMAC and signature will be calculated with existing keys

externalAlias - External alias generated in advance. New key pair must be accessible by this alias

callback - Callback for handling results
