Question

我正在使用Spongycastle并希望以编程方式创建自签名证书。当我在Android中运行以下代码时，我得到java.io.IOException: Wrong version of key store.

我不确定我做错了什么，我认为Spongycastle会是正确的版本？

无论如何这里是代码：

import org.spongycastle.jce.X509Principal;
import org.spongycastle.jce.provider.BouncyCastleProvider;
import org.spongycastle.x509.X509V3CertificateGenerator;

import javax.net.ssl.*;
import java.io.*;
import java.math.BigInteger;
import java.security.*;
import java.security.cert.X509Certificate;
import java.util.Date;

public class HttpsHello {
    private static String domainName = "localhost";
    static { Security.addProvider(new BouncyCastleProvider());  }

    public static void test() {

        try {
            KeyPairGenerator keyPairGenerator = KeyPairGenerator.getInstance("RSA");
            keyPairGenerator.initialize(1024);
            KeyPair KPair = keyPairGenerator.generateKeyPair();

            X509V3CertificateGenerator v3CertGen = new X509V3CertificateGenerator();

             int ran = new SecureRandom().nextInt();
            if (ran < 0) ran = ran *-1;

            BigInteger serialNumber = BigInteger.valueOf(ran);

            v3CertGen.setSerialNumber(serialNumber);
            v3CertGen.setIssuerDN(new X509Principal("CN=" + domainName + ", OU=None, O=None L=None, C=None"));
            v3CertGen.setNotBefore(new Date(System.currentTimeMillis() - 1000L * 60 * 60 * 24 * 30));
            v3CertGen.setNotAfter(new Date(System.currentTimeMillis() + (1000L * 60 * 60 * 24 * 365*10)));
            v3CertGen.setSubjectDN(new X509Principal("CN=" + domainName + ", OU=None, O=None L=None, C=None"));


            v3CertGen.setPublicKey(KPair.getPublic());
            v3CertGen.setSignatureAlgorithm("MD5WithRSAEncryption");

            X509Certificate pkcert = v3CertGen.generateX509Certificate(KPair.getPrivate());
        //    FileOutputStream fos = new FileOutputStream("/path/to/testCert.cert");
          //  fos.write(pkcert.getEncoded());
           // fos.close();

            ByteArrayInputStream cert = new ByteArrayInputStream(pkcert.getEncoded());

            KeyStore ks = KeyStore.getInstance(KeyStore.getDefaultType());

            ks.load(cert,null);
            KeyManagerFactory kmf =
                    KeyManagerFactory.getInstance("SunX509");
            kmf.init(ks, null);
            SSLContext sc = SSLContext.getInstance("TLS");
            sc.init(kmf.getKeyManagers(), null, null);

我认为它在下面一行：

ks.load(cert,null);

'load'用于加载KeyStore文件。您正在尝试加载证书。这两种格式完全不同，这就是你收到错误的原因。

java.io.IOException：密钥库的错误版本。使用SpongyCastle
