RSA算法的解密和加密，用扩展的欧几里得算法求乘法逆元(rsa)

Elgamal数字签名的一个大体验证,用于对一个文件的签名后在进行认证.一个VC开发的小程序.(Elgamal digital signature verification of a general for the signature of a document during the certification after. A small VC development process.)

说明：  一个移位加密算法的源代码，跟大家交流一下。(a shift encryption algorithm source code sharing with you what.)

文件加密使用,可以实现对PC上文件进行加密解密功能(document encryption use, the PC can be achieved on the document encryption and decryption functions)

该文件能用Visual C++6.0打开编译实现加密解密功能，并能通过少量的修改改(修改处程序源码中已标明)镶嵌到其他的程序源码中实现加密解密功能。 可直接使用。 (The file can use Visual C++6.0 to open compiled encryption and decryption functions through a few modifications reform (modify at program source code has been marked) inlaid into the other program source code to achieve encryption and decryption functions. Can be used directly.)

基本古典密码设计——周期为3的多表代替密码的设计和实现(Basic classical cipher design)

整体思路 用createkey.java 文件来产生秘钥，用jiami.java 文件来实 现加密，用jiemi.java 文件来实现解密,用BigInteger.java 来实现 大数的表示及运算，用rsa.java 来实现前端图形界面显示。有关函 数见五个文件里的具体实现。 (The overall outlook createkey.java document used to generate secret keys, used to achieve jiami.java file encryption, used to achieve jiemi.java documents declassified by BigInteger.java to achieve expression of large numbers and calculations, using rsa.java to achieve front-end graphical interface display. Related functions, see the five concrete realization of the document.)

一种加密算法,可以直接对密文进行操作，而不需要知道相应的明文。(homomorphic encryption)
