Encryption 如何使用Virgil Security SDK在android firebase应用程序中添加端到端加密

请帮帮我！在阅读了文档之后，我一直试图在我的Android聊天应用程序中包含一些代码，但没有成功。实际上，我不知道把这些示例代码片段放在哪里

我的应用程序有一个设置/登录活动，其中用户经过身份验证 在他们可以聊天之前。Firebase身份验证如下所示：

public void registerUser(final String email, final String password){
    if(email.equals("") || password.equals("")){
        Toast.makeText(getBaseContext(), "Please enter email and/or password",
                Toast.LENGTH_LONG).show();
    }else{
        //auth is already initialized somewhere
        auth.createUserWithEmailAndPassword(email, password)
        .addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
            @Override
            public void onComplete(@NonNull Task<AuthResult> task) {
                if (task.isSuccessful()) {

                    FirebaseUser user = auth.getCurrentUser();
                    Intent intent = new Intent(SetupActivity.this,
                            MoreActivity.class);
                    intent.putExtra("email", email);
                    intent.putExtra("userID", user.getUid());
                    startActivity(intent);
                }else{
                    Toast.makeText(SetupActivity.this, "Error logging in, try again", Toast.LENGTH_LONG).show();
                }
            }
        });
    }
}

我的问题是加密部分，因为Firebase身份验证和chats实现已经很好地工作了。谢谢你的帮助。

不

e3kit初始化和用户注册应在firebase验证后立即进行。用户注册只发生一次，最好是在注册时，每次登录时初始化。在您的代码中，它将发生在

startActivity（intent）之前

e3kit加密应该在您构建聊天对象之前进行，因此在
Chat Chat=new Chat（userId、message、receiverID，“”）之前确保您执行
message=etree.encrypt（消息、公钥）。当然，解密将在您收到加密消息后发生

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_chat);

        Toolbar toolbar = (Toolbar) findViewById(R.id.chatToolbar);
        setSupportActionBar(toolbar);
        toolbar.setNavigationIcon(getResources().getDrawable(R.drawable.ic_arrow_back_white_24dp));
        toolbar.setNavigationOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                //What to do on back clicked
                onSupportNavigateUp();
            }
        });

        //Get receiver name from Intent extras
        Intent intent = getIntent();
        receiverName = intent.getStringExtra("receiverName");
        toolbar.setTitle(receiverName);

        database = FirebaseDatabase.getInstance();
        reference = database.getReference("chats");

        toolbar.setSubtitle(receiverPhone);

        setSupportActionBar(toolbar);
        getSupportActionBar().setDisplayShowTitleEnabled(true);

        //Firebase instance and user details
        auth = FirebaseAuth.getInstance();
        user = auth.getCurrentUser();
        phone = user.getPhoneNumber();

        userName = user.getDisplayName();
        userId = user.getUid();
        userPhotoUrl = user.getPhotoUrl();

        //Get widgets
        newChat = (EditText) findViewById(R.id.chatMessage);
        receiverMsg = (TextView) findViewById(R.id.receiverMessage);
        myMsg = (TextView) findViewById(R.id.myMessage);

        dateAdded = (TextView) findViewById(R.id.dateAdded);
        receivedDate = (TextView) findViewById(R.id.receivedDate);

        myPicText = (ImageView) findViewById(R.id.myPicture);
        receiverPicText = (ImageView) findViewById(R.id.receiverPicture);

        FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
        fab.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                String message = newChat.getText().toString();
                Chat chat = new Chat(userId, message, receiverID, "");
                DateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mma");
                String date = dateFormat.format(Calendar.getInstance(
                        TimeZone.getDefault()).getTime());

                chat.setTime(date);
                DatabaseReference ref = reference.push();

                ref.setValue(chat);
                newChat.getText().clear();
            }
        });
    }
