我有一个组合的.pem文件，如下所示：

public class Phrases {
    public Context context;
    public static String[] categories = {"feeling","home","work","medical","food","activity","common","emergency"};
    private static Phrases phrases = null;
    public Map<String,String[]> allPhrases = new HashMap<>();

    private Phrases() {
    }

    public static Phrases getPhrases() {
        if(phrases == null) {
            phrases = new Phrases();
        }
        return phrases;
    }

    public void fetchAllPhrases(Context context) {
        this.context = context;
        Resources res = context.getResources();
        allPhrases.put(categories[0],res.getStringArray(R.array.feeling));
        allPhrases.put(categories[1],res.getStringArray(R.array.home));
        allPhrases.put(categories[2],res.getStringArray(R.array.work));
        allPhrases.put(categories[3],res.getStringArray(R.array.medical));
        allPhrases.put(categories[4],res.getStringArray(R.array.food));
        allPhrases.put(categories[5],res.getStringArray(R.array.activity));
        allPhrases.put(categories[6],res.getStringArray(R.array.common));
        allPhrases.put(categories[7],res.getStringArray(R.array.emergency));
//        Log.v("PHRASES",Arrays.toString(allPhrases.toString()));
    }

    public Map<String,String[]> getallPhrases() {
        return allPhrases;
    }
}

我认为这是ssl，key和ca的组合。我需要将其转换为truststore.jks和keystore.jks以用于我的服务。

public class CustomFragment extends Fragment {
    private ArrayAdapter<String> adapter;
    private ListView listView;
    private FloatingactionButton addPhraseButton;
    private TextView phraseTitleTextView;
    private TextToSpeech textToSpeech;
    private String[] phrases;

    @Nullable
    @Override
    public View onCreateView(@NonNull LayoutInflater inflater,@Nullable ViewGroup container,@Nullable Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment_custom,container,false);
        //receive intent
        String categories = getarguments().getString("categories");

        Phrases phrasesObj = Phrases.getPhrases();
        phrasesObj.fetchAllPhrases(view.getcontext());
        phrases = phrasesObj.getallPhrases().get(categories);

        phraseTitleTextView = view.findViewById(R.id.label_phrases_txtview);
        addPhraseButton = view.findViewById(R.id.add_phrases_btn);
        // setting local for text to speech
        textToSpeech = new TextToSpeech(getactivity().getapplicationContext(),new TextToSpeech.OnInitListener() {
            @Override
            public void onInit(int status) {
                textToSpeech.setLanguage(Locale.US);
            }
        });

        //setting adapter and listview
        adapter = new ArrayAdapter<String>(getcontext(),R.layout.entry_item,R.id.phrase_textview,phrases);
        listView = (ListView) view.findViewById(R.id.phrases_list);
        listView.setadapter(adapter);
        listView.setItemsCanFocus(true);

        listView.setOnItemClicklistener(new AdapterView.OnItemClicklistener() {
            @Override
            public void onItemClick(AdapterView<?> paren,View view,int position,long id) {
                String text = phrases[position];
                Toast.makeText(getcontext(),text,Toast.LENGTH_LONG).show();
                textToSpeech.speak(text,TextToSpeech.QUEUE_FLUSH,null,null);
            }
        });
        return view;
    }
}

但是抛出：

-----BEGIN RSA PRIVATE KEY-----
...
-----END RSA PRIVATE KEY-----
-----BEGIN CERTIFICATE-----
...
-----END CERTIFICATE-----
-----BEGIN CERTIFICATE-----
...
-----END CERTIFICATE-----

如果我尝试也发生以下情况：

openssl pkcs12 -export -out cert.pkcs12 -in cert
keytool -importcert -v -trustcacerts -alias eb-srv -file cert.pkcs12 -keystore truststore.jks
