Class Overview
This class provide API's extended from KeyPairGeneratorSpi.
If vendor want to support KeyPairGenerator as JCE, plugin application should implement this Spi and add as Service Provider.

Public Methods

Bundle
getProperty
()
API to get the properties set by UCM framework during SPI call.
Returns
- Bundle Bundle calling applicaiton information
Usage
To perform crypto operation properly, plugin application should know caller information.
Plugin application can use this API to get caller user Id, resource Id, caller application Uid and owner Id
public class SimpleUcmAgentKeyPairGeneratorSpi extends UcmAgentProviderImpl.UcmAgentKeyPairGeneratorSpi {
public SimpleUcmAgentKeyPairGeneratorSpi(Context ctx, String algorithm) {
Bundle bundle = getProperty();
int userId = bundle.getInt(UcmAgentSpiProperty.KEY_USER_ID, -1));
int resourceId = bundle.getInt(UcmAgentSpiProperty.KEY_RESOURCE_ID , -1));
int callerId = bundle.getInt(UcmAgentSpiProperty.KEY_CALLER_UID , -1));
}
