First, prefaceWith the broadcast technology hot, all the Live app, the early live app's various request protocol parameter information did not do any encryption measures, but slowly someone began to use the back door began to brush powder attention tool, you can make a new small Hua Dan minute into the net red. So somewhere in this problem, the live app starts encrypting the network request parameters. So that is the focus of this article analysis. Th

Preface I have written many articles about data migration and introduced many tools and features related to HDFS, suchDistcp, viewfilesystemAnd so on. But the theme I want to talk about today has moved to another field.Data securityData security has always been a key concern for users. Therefore, data managers must follow the following principles: The data is not lost or damaged, and the data content cannot be accessed illegally. The main aspect described in this article is the last point in the

As with symmetric encryption algorithms, the related classes of all asymmetric algorithms also exist in the System.Security.Cryptography namespace. In this namespace,. NET Framework provides four kinds of asymmetric encryption algorithms, such as RSA, DSA, ECC and Differ-hellman. This section describes several of the major related classes and interfaces. The relevant content of the application will be descr

The last blog about how to play the hash algorithm, but that article did not explain clearly. This blog post I will try to make the things that are not explained clearly. Of course, the theme of this article is to play symmetric encryption. . NET of symmetric encryption technology There are mainly such several: Des,aes,rijndael,tripledes (3DES). Now, let's play around with them! As with the previous blog p

To start encryption: 1.BIOS Currently, the simplest and easiest system password is the number of BIOS passwords. Set the BIOS password, each boot into the Windows operating system, the computer will be prompted to enter the BIOS password, only the correct input password, before the start of the winodows system, if the password is not correct, then the illegal intruder can only do points on the boot, shutdown operation. Start the computer, press the DE

1. Java Security Architecture 1.1 Introduction to Java Security architectureJava provides classes and interfaces for the security framework. The JDK security API is the core API for the Java programming language, located in the Java.security package (and its child packages), and in the SUN.SECURITYAPI package (and its child packages). Designed to help developers use both low-level and advanced security features in their programs.The first release of JDK security in JDK 1.1 introduces the Java Cr

With the development of symmetric cipher, the DES data Encryption Standard algorithm, because of its small key length (56 bits), has not adapted to the requirements of today's distributed open Network for data encryption security, so 1997 NIST publicly recruited new data encryption Standard, namely AES[1]. After a tricycle selection, the Rijndael algorithm submit

(i) Symmetric encryption (symmetric cryptography)Symmetric encryption is the fastest and simplest way to encrypt encryption (encryption) and decryption (decryption) with the same key (secret key). Symmetric encryption has many algorithms, and because of its high efficiency,

From: http://snowolf.iteye.com/blog/379860 Encryption and decryption were once an important component of my graduation project. After many years of work, it was too simple to recall the encryption and decryption algorithm at that time.To put it bluntly, here we mainly describe some encryption and decryption algorithms implemented by Java, and finally introduce di

One place in the project uses the need to encrypt the user ID and pass it to the next contact for the reverse solution. (Forgive me not to disclose too many-_-!), the first thought is a function in the kangsheng ucenter, later searched, in the concise magic also found a simple method, hence the integration of the next, formed its own use of the function. First, symmetric encryption The sender uses the secret key and algorithm to send out the ciphert
