Question

我正在创建一个 java独立应用程序，它使用 bouncycastle。一切都在eclipse中运行。我正在创建一个 jar with dependencies ，如this。

当我使用“java -jar myapp-0.0.1-SNAPSHOT-jar-with-dependencies.jar”运行应用程序时。

我收到以下错误：

java.io.IOException: exception encrypting data - java.lang.SecurityException: JCE cannot authenticate the provider BC

我的代码：

    Security.addProvider(new BouncyCastleProvider());        
    String keystoreDirectory = "C:/myapp/security";
    File file = new File(keystoreDirectory + "/" + PRIVATE_KEY_FILE);

    if (!file.isFile()) {
        try {

            Configuration idOrganization = configurationBoundary.find(Configuration.ID_ORGANIZATION);

            KeyStore store = KeyStore.getInstance("PKCS12", SECURITY_PROVIDER);
            char[] password = KEY.toCharArray();

            store.load(null, password);

            KeyPairGenerator keyPairGenerator = KeyPairGenerator.getInstance("RSA", SECURITY_PROVIDER);
            keyPairGenerator.initialize(2048);
            KeyPair pair = keyPairGenerator.generateKeyPair();

            X500Name issuer = new X500Name("CN=" + idOrganization.getProperty());
            BigInteger serial = BigInteger.valueOf(new SecureRandom().nextLong());
            Date notBefore = new Date(System.currentTimeMillis() - 10000);
            Date notAfter = new Date(System.currentTimeMillis() + 24L * 3600 * 1000 * 365);
            X500Name subject = new X500Name("CN=" + idOrganization.getProperty());
            SubjectPublicKeyInfo publicKeyInfo = SubjectPublicKeyInfo.getInstance(pair.getPublic().getEncoded());
            X509v3CertificateBuilder builder = new X509v3CertificateBuilder(issuer, serial, notBefore, notAfter, subject, publicKeyInfo);

            ContentSigner sigGen = new JcaContentSignerBuilder("SHA256WithRSAEncryption").setProvider(SECURITY_PROVIDER).build(pair.getPrivate());
            X509Certificate cert = new JcaX509CertificateConverter().setProvider(SECURITY_PROVIDER).getCertificate(builder.build(sigGen));

            store.setKeyEntry(idOrganization.getProperty(), pair.getPrivate(), null, new java.security.cert.Certificate[]{cert});

            try (FileOutputStream fos = new FileOutputStream(file)) {
                store.store(fos, password); //Error here
            }

        } catch (Exception ex) {
            logger.error("Keystore creation error", ex);
        }
    }

有什么想法吗？感谢。

Bouncycastle jar必须签名，不能放在胖罐里面。您可以单独发货并使用maven-shade-plugin：

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-shade-plugin</artifactId>
            <version>2.3</version>
            <configuration>
                <artifactSet>
                    <excludes>
                        <exclude>org.bouncycastle:*:*:*</exclude>
                    </excludes>
                </artifactSet>
                <transformers>
                    <transformer
                        implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
                        <manifestEntries>
                            <Main-Class>com.example.Main</Main-Class>
                            <Class-Path>. ./lib/bcprov-jdk16-1.46.jar</Class-Path>
                        </manifestEntries>
                    </transformer>
                </transformers>
                <shadedArtifactAttached>true</shadedArtifactAttached>
                <shadedClassifierName>fat</shadedClassifierName>
            </configuration>
            <executions>
                <execution>
                    <phase>package</phase>
                    <goals>
                        <goal>shade</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>

在ManifestResourceTransformer中，您可以为bouncycastle jar依赖项定义类路径。

不幸的是，JCE要求JAR与Bouncy Castle签名并创建可执行的jar废墟。准备单独运送BouncyCastle罐。

你实际上可以使用Spring Boot或类似的东西 - 它将jar嵌入fat jar中，然后解压缩并加载它们。或类似Spring Boot的东西。

我已经用这个插件包装了一个胖罐

https://github.com/nthuemmel/executable-packer-maven-plugin

它可以很好地遮挡并在肥胖的罐子里使用充气城堡

Answer 4

问题是BouncyCastle jar已签名，必须保持原样。对我来说，包括Maven中的依赖关系，范围是＆＃39;提供＆＃39;工作

    <dependency>
        <groupId>org.bouncycastle</groupId>
        <artifactId>bcprov-jdk15on</artifactId>
        <version>1.55</version>
        <scope>provided</scope>
    </dependency>

bouncycastle错误“JCE无法验证提供程序BC”与“jar-with-dependencies”
