des和rsa的算法演示文档 (des and rsa algorithm presentation)

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:)

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)

检测CRC编码 看CRC编码在传输后是否有错误 有变动 (Detection CRC codes to see whether the CRC coding errors in the transmission there is a change)
