Description: 与上一个 asp版本的相比较，功能上基本一样，由于是入门版，用的基本都是最基础的东西。只在截取字符串和 md5加密上用到了两个javaBeans，由于用的是以前的模版，一个星期就搞定了，总结了上次的经验，在页面调用，代码规范上做了很大的调整，希望对那些初学jsp的人带来一丝启发。。。

Only in the interception of the string and md5 encryption used on the two javaBeans, as a result of using a previous template, get a week, summed up the previous experience in the page call, code specification to do a lot of adjustments, jsp beginner to those who wish to bring a ray of inspiration. . .

Description: 实现移位密码的加密，解密过程.移位密码，即向后移k位，k是密钥,是任意的。选用一个英文短语或单词作为密钥，去掉其中重复的字母得到一个无重复字母的字符串，然后将字母表中的其他字母依此写于此字母串之后。找出明文字母在原字母表中位置,则在加入密钥的字母表中该位置上的对应字母就是密文。-To realize the shift encryption and decryption process. Shift the password, that is, move backward k-bit, k is the key, is arbitrary. An English phrase or word used as a key, remove the duplicate letters which have no repeated letters of a string, and then the other letters in the alphabet so after writing this letter string. Expressly identify the alphabet letters in the original location, then add the key position on the alphabet letter that corresponds to ciphertext. Platform: |

Description: 实习三 基于RSA的公钥加密
一、实习目的
1、 理解公钥密码算法，熟悉常有的密码算法：RSA、椭圆曲线密码体制
2、 以RSA加密算法为例，掌握公钥密码算法加解密过程的实现。
二、实习内容
以RSA为例，利用java中的相关类实现对指定字符串的加解密。
1、 生成公钥密钥对
(1)利用java中的KeypairGenerator类创建公钥密钥对，利用KeypairGenerator的静态方法getInstance（）获得KeypairGenerator类型的对象，所需参数为加密算法的名称RSA。

(2)利用KeyPairGenerator类的genKeyPair()方法返回生成的密钥对：
KeyPair kp = kpg.genKeyPair()
(3)返回此密钥对的公钥组件的引用和私钥组件的引用
PublicKey pbkey = kp.getPublic()
PrivateKey prkey = kp.getPrivate()
(4)将生成的公钥写入文件Skey_RSA_pub.dat
FileOutputStream f1 = new FileOutputStream("Skey_RSA_pub.dat")
ObjectOutputStream b1 = new ObjectOutputStream(f1)
b1.writeObject(pbkey)
用同样的方法将私钥写入文件Skey_RSA_pri.dat
