Description: ava加密扩展即Java Cryptography Extension，简称JCE。它是Sun的加密服务软件，包含了加密和密匙生成功能。JCE是JCA（Java Cryptography Architecture）的一种扩展。 JCE没有规定具体的加密算法，但提供了一个框架，加密算法的具体实现可以作为服务提供者加入。除了JCE框架之外，JCE软件包还包含了SunJCE服务提供者，其中包括许多有用的加密算法，比如DES（Data Encryption Standard）和Blowfish。 为简单计，在本文中我们将用DES算法加密和解密字节码。下面是用JCE加密和解密数据必须遵循的基本步骤： 步骤1：生成一个安全密匙。在加密或解密任何数据之前需要有一个密匙。密匙是随同被加密的应用一起发布的一小段数据，Listing 3显示了如何生成一个密匙。 【Listing 3：生成一个密匙】 -expansion that Java Cryptography Extension, referred to JCE. It is Sun's encryption software, including encryption and key generation functions. JCE is JCA (Java Cryptography Architecture), an extension. JCE no specific encryption algorithms, but provides a framework, the specific encryption algorithm can achieve as a service provider to join. Apart from the JCE framework, JCE package also includes SunJCE service providers, including many useful encryption algorithms such as DES (Data Encryption Standard) and the Blowfish. For simple terms, in this paper we will use DES encryption and decryption algorithms byte code. Below is JCE encryption and decryption of data must adhere to the basic steps : Step 1 : Generating a security keys. In any encryption or decryption of data is needed befo

Description: 根据设计要求：1）具有文件加密和解密功能；2）具有加解密速度统计功能；3）采用密文反馈链接和密文挪用短块处理技术。我们可以知道，程序要有加密模块、解密模块、子密钥生成模块，这三个模块构成DES算法。DES算法再构成3DES，这很简单，只要加个密钥便可实现。3DES还必须工作在密文反馈连接模式下和使用密文短块挪用技术。至于速度统计功能就很好实现，用文件长度除以处理时间便是加解密速度。-based on the design requirements : 1) with file encryption and decryption function; 2) the speed with the encryption and decryption functions of statistics; 3) Use of dense text links and feedback secret misappropriation short pieces of text processing technology. We know that procedures have encryption module, decryption modules for key generating modules, which constitute three modules DES algorithm. DES algorithm constitute 3DES, this is very simple, as long as add key can be reached. 3DES must also work in close link text feedback mode and the use of short text block secret misappropriation of technology. As for the speed of statistical functions properly achieved, divided by the length of documents with the processing time is the speed encryption and decryption.

Description: des算法简单实现。它以64位的明文和56位的密钥作为输入，通过DES加密运算产生64位密文输出。其解密过程利用同以密钥和算法将密文还原成明文。因为java语言的安全性＆网络处理能力强，所以就利用了java语言编写-des simple algorithm to achieve. It's expressly 64 and 56 as the key input, through DES encryption algorithms have 64 ciphertext output. Its use decryption process with a key and cipher algorithm reduced explicitly. Java language because of the security & network processing capability, on the use of the Java language

Description: Des算法是一种标准的对称加密算法，其精华就是明文经过一系列的复杂变化后，一般在不知密码的情况下要把它的恢复很难。
算法可以由四个部分描述：
1.获取16个子密钥
2.初始置换置换函数ip
3.加密函数f
4.末置换函数
-Des Algorithm is a standard symmetric encryption algorithm, and its essence is clear after a series of complex changes in law, the general in the circumstances I do not know the password should be difficult to restore it. Algorithm can be described in four parts: 1. To obtain 16 sub-keys 2. The initial replacement replacement function ip 3. Cryptographic function f 4. At the end of displacement function
