Many of us already use OpenSSL to create RSA private keys or certificate signing requests (CSRs). But have you ever known that you can use OpenSSL to test your computer's speed? Or can you use it to encrypt a file or a message? This article will show you a few easy-to-learn tips on how to

Encrypt encrypted messages sent externally I have modified the previous GetXmlDocument method so that it can use the X.509 asymmetric encryption technique implemented by WSE. Encrypted response message, the Findcertificatebysubjectstring method can be used to receive a public backup of the client certificate, a client certificate from a personal storage room from the local machine account. This certificate

, this algorithm is only available to data publishers. In the android program, you only need to call a Java method to obtain map data: Result = JNI. getencrypttile (DeviceID, location, bundlebase, level, row, col ); Now, even if the DEX file in the android program is decompiled, you cannot know the actual algorithm called in the dynamic link library behind the code. The following describes how to

Android uses jni to encrypt and decrypt strings for analysis. androidjni Analysis of string encryption and decryption using jni in android Recently, a demand for projects is to encrypt users' sensitive information, such as users' account passwords, mobile phone numbers, and other private information. In java, we can us

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

After a busy week and finally having time to write something, we continue to introduce another way for Android APK to prevent anti-compilation technology.

A requirement of a recent project is that the function of a module can be used only by entering the serial number. enter the serial number, encrypt it, and package it into a file and store it in sdcard. Verify whether such a file exists under sdcard next time. How to encrypt and decrypt data in Java: There are two classes: Keygenerator: This class provides (symmetric) key generator functions. Cipher: This c

Recently, in my project, I needed to encrypt some SQL statements on the android client. I used DES encryption, and the result encryption appeared. javax.crypto.BadPaddingException: Given final block not properly padded Such an error, or the garbled problem, is very tangled! When I checked some information, it may be a key issue or a code issue. I found that the key is correct, that is, when the key is creat

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

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
