我从HTTPConnection调用中获得证书，并保存在信任管理器中，但是webView需要SSL而不是X509证书，可以转换吗？

// 从HTTPConnection调用中获取X509证书
X509Certificate x509Certificate = getCertificateFromHTTPConnection();

try {
    // 创建SSLContext对象
    SSLContext sslContext = SSLContext.getInstance("TLS");
    TrustManagerFactory trustManagerFactory = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
    KeyStore keyStore = KeyStore.getInstance(KeyStore.getDefaultType());
    keyStore.load(null, null);
    keyStore.setCertificateEntry("certificate", x509Certificate);
    trustManagerFactory.init(keyStore);
    sslContext.init(null, trustManagerFactory.getTrustManagers(), null);

    // 创建SSLSocketFactory
    SSLSocketFactory sslSocketFactory = sslContext.getSocketFactory();

    // 将SSLSocketFactory设置给webView
    webView.setSSLSocketFactory(sslSocketFactory);
} catch (Exception e) {
    e.printStackTrace();
}
