Simple-CaesarCipher

实现对单文件的DES加密解密，不限制大小，DES加密部分自写，非调用，用于学习DES原理。(The realization of the single document DES encryption and decryption, no limit to the size, DES encryption part self written, non call, for learning DES principle.)

RSA数字签名的源代码 vc++6.0实现的版本(RSA Digital Signature vc source code version 6.0)

将国密算法SM3, SM4 ECB的C代码打包成dll库。 然后在C#中进行调用。 有输入输出接口，测试结果正确。 包含所有源代码，可在此基础上进一步开发(The C code of the Chinese national algorithm SM3, SM4 ECB is packaged into a dll library and then called in C# with input and output interfaces. The test result is correct. Contains all source code and can be further developed on this basis)

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)

DVB 加扰软件，对TS流文件进行加扰，符合DVB标准(it s a dvb scramble software . it can scrambling ts stream file ,which apply for dvb standards)

说明：  编制程序，将输入的一行字符以加密的形式输出，然后将其解密，解密的字符串序列与输入的正文相比较，吻合时输出解密的正文，否则解密失败。 加密时，将每个字符的ascii码依次反复加上“4962873”中的数字，并在32（‘’）~122（‘z’）之间作模运算。解密与加密的顺序相反。例如输入正文“the result of 3 and 2 is not 8” 结果为： (Programming, the input line character output in an encrypted form, and then decrypted, the decrypted text sequence of characters compared with the input, output to decrypt the body of the agreement, otherwise the decryption failed. Encryption, ascii code of each character in turn repeatedly with &quot 4962873&quot in the figures, and 32 (' ' )~ 122 (' z' ) as a model between the operations. Decryption and encryption in reverse order. For example, enter the text &quot the result of 3 and 2 is not 8&quot results:)
