[OS program] src DL : 0: 实习二分组密码加密一、实习目的 1、理解对称加密算法的原理，熟悉常用的对称加密算法：DES、TripleDES、Blowfish； 2、以DESede加密算法为例，掌握分组加密算法加、解密过程的实现。二、实习内容 1．[基本要求] 以DES/DESede为例，利用java中的相关类实现对指定字符串的加、解密。 2．[实现提示] (1) 可以利用java中的KeyGenerator类创建对称秘钥，利用工厂类KeyGenerator的静态方法getInstance()获得KeyGenerator()类对象； (2) 方法getInstance()的参数为字符串类型，指定加密算法的名称如：Blowfish、DES、DESede、HmacMD5或HmacSHA1等； (3) 利用工厂类Cipher的对象可以创建密码器。同样的，getInstance()的参数为字符串类型，指定加密算法的名称 -Internship two block cipher encryption An internship purpose An understanding of the principles of symmetric encryption algorithms, symmetric encryption algorithms used are familiar: DES, TripleDES, Blowfish 2, DESede encryption algorithm, for example, plus master block encryption algorithm to achieve decryption process. Second, the practical content 1. [Basic requirements] With DES/DESede for example, the use of java in the relevant class implements the specified string encryption and decryption. 2. [Achieve prompt] (1) can be used to create a java class in KeyGenerator symmetric secret key, use the static method getInstance factory class KeyGenerator of () to get KeyGenerator () class object (2) the method getInstance () argument is a string type, specify the name of the encryption algorithm, such as: Blowfish, DES, DESede, HmacMD5 or HmacSHA1 etc. (3) the use of factory class Cipher objects can create a password control. The same, getInstance () argument is a string typ
