Bouncy Castle升级版本1.60和1.6.1或更高版本

Question

将bcprov-jdk15on-160.jar和bctls-jdk15on-160.jar升级到bcprov-jdk15on-161.jar和bctls-jdk15on-161.jar或更高版本时，我们遇到一个问题

java.lang.InternalError：无法在org.bouncycastle.jcajce.provider.drbg.drbg$urlseededsecurerandom$1上打开随机源。在org.bouncycastle.jcajce.provider.drbg.drbg$urlseededsecurerandom$1上运行(drbg.java:294)。在.Reflect.NativeConstructorAccessorImpl.NewInstance（NativeConstructorAccessorImpl.java:39)位于Sun.Reflect.DelegatingConstructorAccessorImpl.NewInstance（DelegatingConstructorAccessorImpl.27)位于java.lang.Reflect.Constructor.NewInstance（DelegatingConstructorAccessorImpl.NewInstance）位于java.lang.Reflect.Constructor.NewInstance（

多谢了。

public class BCUpgradeTest {

    public static void main(String[] args) {
        try {
            Security.insertProviderAt(new BouncyCastleJsseProvider(), 1);
            Security.insertProviderAt(new BouncyCastleProvider(), 1);
            KeyAgreement ka = KeyAgreement.getInstance("ECDH");
            System.out.println(ka.getProvider().getName());
        } catch (Exception e) {
            e.printStackTrace();
        }

Thanks multipybyzer0您的代码解决了关于

java.lang.InternalError：无法打开随机源

bcprov-jdk15on-162.jar和bctls-jdk15on-162.jar仍然存在另一个问题

import java.lang.reflect.Field;
import java.security.Provider;
import java.security.Security;
import java.util.Properties;

import javax.crypto.KeyAgreement;

import org.bouncycastle.jce.provider.BouncyCastleProvider;
import org.bouncycastle.jsse.provider.BouncyCastleJsseProvider;

public class BCUpgradeTest {

    public static void main(String[] args) {
        try {
            Field propsField = Security.class.getDeclaredField("props");
            propsField.setAccessible(true);
            Properties props = (Properties) propsField.get(null);
            props.remove("securerandom.source");
        } catch (Exception e) {
            System.err.println("Unable to modify java.lang.Security properties!");
            System.err.println("BouncyCastle DRBG may fail.");
        }

        try {
            BouncyCastleJsseProvider jsseProvider = new BouncyCastleJsseProvider();
            int jssePos = Security.insertProviderAt(jsseProvider, 1);
            BouncyCastleProvider castleProvider = new BouncyCastleProvider();
            int bcPos = Security.insertProviderAt(castleProvider, 1);

            System.out.println("jssePos = " + jssePos);
            System.out.println("bcPos = " + bcPos);

            System.out.println(castleProvider.getVersion());
            System.out.println(BCUpgradeTest.class.getClassLoader().getResource("org/bouncycastle/LICENSE.class"));

            Provider[] providers = Security.getProviders();
            for (int i = 0; i < providers.length; i++) {
                System.out.println("name : " + providers[i].getName() + "; version = " + providers[i].getVersion());
            }

            KeyAgreement ka = KeyAgreement.getInstance("ECDH", castleProvider);
            System.out.println(ka.getProvider().getName());
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

下面是控制台的输出

jssePos = 1
bcPos = 1
1.62
jar:file:/D:/Eclipse/workspace/BCTestProject/libs/bcprov-jdk15on-162.jar!/org/bouncycastle/LICENSE.class

name : SunSASL; version = 1.5
name : XMLDSig; version = 1.0

请注意，我使用的是官方的jar文件，没有进行任何修改。
