In the previous article, "Receiving text messages", we learned that the message between the public service and the server is "bare-Ben" (that is, the plaintext transmission, which can be seen through the capture packet). Obviously this is for some high security requirements of the large enterprise service number, such as banks, securities, telecommunications operators or

Based on personal experience, this article describes how to use Wireshark (Ethereal's new name) to view encrypted messages in the captured SSL (including HTTPS). When you configure HTTPS (based on TLS/SSL) with servers such as Tomcat, you often need to use Wireshark to grab the package and want to view the HTTP messages. However, HTTPS traffic is

Talking about the Android Market Environment, non-encrypted apps will die, androidapps My questions are a little eye-catching, and of course some people think that I am alarmist. Then, let's hear if I have a bit of truth. The APP in the title should exclude the small developers who only want to push advertisements by the APP. It is true that these developers do not have a high starting point, I just want to

The smack package used in Android is actually called Asmack, which provides two different ways to connect: Sockets and HttpClient. It also provides many APIs for operating the XMPP protocol and facilitates the expansion of various custom protocols. We do not need to redefine a set of receive mechanisms to extend the new protocol, just inherit and then handle our own protocol in the class. Today, the main point of this article is to say two points, the

My topic is a bit of attention, and of course there are spray uneven people think I am alarmist, then listen to what I say is not so little truth. The app in the title excludes the niche developers who just want to push ads on the app, but these developers don't have a high starting point, they just want to rely on the Android platform's easy-to-use app development to earn two small ads (including myself, of course), and their goal is not to develop

The answer is yes, at least better than clear text.When the client registers and logs in: a feasible method is that the client submits the MD5 (password) password (as described above, this method simply protects the password and is likely to be looked up for the password).When registering: The server-side database stores the password through MD5 (SALT+MD5 (password)) rules, which are stored only on the server and randomly generated each time the password is stored .

Recently, in order to learn about Android development, I specially transplanted the original MingQQ Windows version to Android to train my hands. Through this exercise, I learned a lot about Android development, especially the interface development. The MingQQ interface imitates the basic functions of Android QQ. Alt

Remove Google's native service. Bought some like what the cottage machine or Huawei such domestic machine, may Google's services are not. And like those out there might be built in. No way, finally transferred to the third party push service platform, Aurora Push, the following will introduce how to use the Aurora pus

Preface:Most mobile applications now have the ability to get messages in real time. Simply put, they have the initiative to send messages and the passive right to receive messages. For example, QQ, weather forecast, etc. Believe in benefits and user experience. Raise questions:This function must involve the client and server. So how does the client implement real
