Question

我有以下代码：

SSLContext sslContext = SSLContext.getInstance("TLS", BouncyCastleProvider.PROVIDER_NAME);
sslContext.init(keyManagerFactory.getKeyManagers(), null, null);
SSLEngine sslEngine = sslContext.createSSLEngine();
String[] suites = { "TLS_ECDHE_ECDSA_WITH_AES_128_CCM_8" };
sslEngine.setEnabledCipherSuites(suites);

感谢。

修改：我发现我应该使用需要BouncyCastleJsseProvider对象的SecureRandom，如下所示：

sslContext.init(keyManagerFactory.getKeyManagers(), null, new SecureRandom());

使用新的提供程序后，我在我的代码库中获得了以下堆栈跟踪，据我所知，它应该像以前一样工作：

我做了以下工作以使其正常工作。

添加提供商：BouncyCastleProvider和BouncyCastleJsseProvider

Security.addProvider(new BouncyCastleProvider());
Security.addProvider(new BouncyCastleJsseProvider());

使用SSLContext

创建BouncyCastleJsseProvider

SSLContext sslContext = SSLContext.getInstance("TLS", BouncyCastleJsseProvider.PROVIDER_NAME);

使用sslContext SecureRandom的实例初始化BouncyCastleProvider

sslContext.init(
        keyManagers,
        trustManagers,
        SecureRandom.getInstance("DEFAULT", BouncyCastleProvider.PROVIDER_NAME));

您可能需要使用KeyManagerFactory和BouncyCastleJsseProvider算法创建PKIX

KeyManagerFactory keyManagerFactory = KeyManagerFactory.getInstance("PKIX", BouncyCastleJsseProvider.PROVIDER_NAME);

现在，我们可以启用密码套件

SSLEngine sslEngine = sslContext.createSSLEngine();
String[] suites = { "TLS_ECDHE_ECDSA_WITH_AES_128_CCM_8" };
sslEngine.setEnabledCipherSuites(suites);

如何将SSLEngine限制为TLS_ECDHE_ECDSA_WITH_AES_128_CCM_8 CipherSuite？
