Description: 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
