如何将 SSLEngine 限制为 TLS_ECDHE_ECDSA_WITH_AES_128_CCM_8 CipherSuite？

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);

谢谢。

编辑：我发现我应该使用需要 SecureRandom 对象的 BouncyCastleJsseProvider，像这样：

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

使用新提供程序后，我的代码库中得到以下堆栈跟踪，据我所知，它应该像以前一样工作：

为了让它正常工作，我做了以下操作。

添加提供商：BouncyCastleProvider 和 BouncyCastleJsseProvider

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

使用BouncyCastleJsseProvider

创建SSLContext

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

使用 SecureRandom 的实例和 BouncyCastleProvider

初始化 sslContext

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

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

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

现在，我们可以启用密码套件了

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