Class GraalCompileFixCryptoRegistrar

java.lang.Object

de.adorsys.datasafe.cli.hacks.graalfeature.GraalCompileFixCryptoRegistrar

All Implemented Interfaces:

org.graalvm.nativeimage.hosted.Feature

public class GraalCompileFixCryptoRegistrar
extends Object
implements org.graalvm.nativeimage.hosted.Feature

Bouncy Castle attempts to access SecureRandom in CryptoServicesRegistrar class, during CLI generation. Because it is not allowed to have NativePRNG in image heap this breaks compilation. We fix this by setting CryptoServicesRegistrar#defaultSecureRandom to NoOpRandom that is simply stub class. Then, in runtime in main() CLI simply sets defaultSecureRandom to null before doing any useful work and such trick forces CryptoServicesRegistrar to get correct SecureRandom implementation, because when it is null BC initializes the field.
