Ich möchte Android KeyStore mehrere Zertifikate aus der Ressourcendatei hinzufügen:

if (sslContext==null) {
        // loading CA from an InputStream
        InputStream is = AVApplication.getContext().getResources().openRawResource(R.raw.wildcard);
        String certificates = Converter.convertStreamToString(is);
        String certificateArray[] = certificates.split("-----BEGIN CERTIFICATE-----");

        for (int i = 1; i < certificateArray.length; i++) {
            certificateArray[i] = "-----BEGIN CERTIFICATE-----" + certificateArray[i];
            //LogAV.d("cert:" + certificateArray[i]);

            // generate input stream for certificate factory
            InputStream stream = IOUtils.toInputStream(certificateArray[i]);

            // CertificateFactory
            CertificateFactory cf = CertificateFactory.getInstance("X.509");
            // certificate
            Certificate ca;
            try {
                ca = cf.generateCertificate(stream);
            } finally {
                is.close();
            }

            // creating a KeyStore containing our trusted CAs
            KeyStore ks = KeyStore.getInstance("BKS");
            ks.load(null, null);
            ks.setCertificateEntry("av-ca" + i, ca);

            // TrustManagerFactory
            String algorithm = TrustManagerFactory.getDefaultAlgorithm();
            TrustManagerFactory tmf = TrustManagerFactory.getInstance(algorithm);
            // Create a TrustManager that trusts the CAs in our KeyStore
            tmf.init(ks);

            // Create a SSLContext with the certificate that uses tmf (TrustManager)
            sslContext = SSLContext.getInstance("TLS");
            sslContext.init(null, tmf.getTrustManagers(), new SecureRandom());
        }

    }

    return sslContext;

Nur das letzte Zertifikat der Datei funktioniert! Es scheint, dass das Zertifikat das andere überschreibt.

Datei sieht so aus:

-----BEGIN CERTIFICATE-----
    cert 
-----END CERTIFICATE-----
-----BEGIN CERTIFICATE-----
    cert 
-----END CERTIFICATE-----
-----BEGIN CERTIFICATE-----
    cert 
-----END CERTIFICATE-----

Ich hoffe, jemand kann mir helfen! :)
