现代密码学课设——SHA（安全哈希算法Secure Hash Algorithm）算法编程(failed to translate)

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.)

加密算法RSA，DSA等，用C++实现，内附加有详细的说明(Encryption algorithm RSA, DSA, etc., using C++ Realize, with additional detail has)

shiftcipher加密解密算法实例 使用shiftcipher算法加密字符串 可输入任意密钥(shiftcipher examples of encryption and decryption algorithms String encryption algorithm using the shiftcipher Can enter any key)

DES加密的MFC实现,主要包括两部分组成，有字符串加密和文件加密两种模式，实现了3DES功能，让加密更安全(including string and files by DES)

基于国密算法SM3实现HMAC，输入密钥和消息，可产生HASH验证码，C环境下调试成功(Based on the countries close algorithm realization SM3 HMAC, input key and news, can produce HASH verification code, C environment debugging success)

通过调用openssl库进行aes加密，本程序已编译好了openssl，无需在进行编译！生成时请引用lib文件(By calling the openssl library aes encryption, the program has compiled the openssl, without making compilation! Please cite lib files generated)

题目：某个公司采用公用电话传递数据，数据是四位的整数，在传递过程中是加密的，加密规则如下： 　　　 每位数字都加上5,然后用和除以10的余数代替该数字，再将第一位和第四位交换，第二位和第三位交换。 1.程序分析： 2.程序源代码：(Topic: a company USES the public telephone relay data, data is four integers, in the relay in the process is encrypted, encryption rules are as follows: Each Numbers add 5, then use and divided by the number of 10 instead of a remnant, then the first and fourth exchange, the second and third exchange. 1. The program analysis: 2. The source code:)

说明：  用C++实现的图像加密和解密算法代码,功能强大(Using C++ implementation of image encryption and decryption algorithm code, powerful)
