用C/C++实现加解密算法及其应用：DES（或AES）和基于DES（或AES）的CMAC。(With C/C++ achieve encryption and decryption algorithm and its application: DES (or AES) and based on DES (or AES) of CMAC.)

实现维吉尼亚密码，用键盘接收明文和密钥，屏幕打印密文和解密后的明文。 可以实现：大小写敏感，明文小写则密文大写，明文大写则密文小写输出，注意输入的健壮性控制，明文字符超出字符集后保留原文(Virginia to achieve the password, use the keyboard to receive the plaintext and the key, the screen printing ciphertext and the decrypted plaintext. Can be achieved: case sensitive, then the ciphertext plaintext lowercase uppercase, lowercase plaintext ciphertext output is capital, pay attention to the robustness of the control input, plaintext characters out retain the original character set)

以C++语言在微机上实现了美国数据加密标准DES。可随微机软盘任意路径下的任何文件，加密，加密文件可在软、硬盘任何目录下或在网络中传送；另一方面可对软、硬盘中的任何文件进行解密，解密后的文件除在末尾多出几个空格符外与原文件完全相同，绝不影响EXE文件，COM文件或数据库文件的使用。密钥有加密者在键盘输入8个字符。(In c++ language microcomputer to U.S. data encryption standard DES. With the computer floppy disk arbitrary path of any of the files, encryption, encrypt files can be in soft, hard disk any directory or in the network transmission On the other hand, soft, hard disk to the any classify documents, the decrypted file in the end in a few more the space appears with the original documents are all the same, never affect EXE file, COM file or database files use. Key there are JiaMiZhe in keyboard input 8 characters. )

文件加密器,实现对文件加密,用来学习的代码(File encryption, encrypting files, the code used to study)

DES加密方法加密BMP图像，CBC方式实现。(DES encryption methods encryption BMP image, CBC way.)

基于crypto++实现RSA密钥对生成，密钥长度1024，vs2010实现(generate RSA key pair based on Crypto++，and save the key pairs which is 1024 bit in txt file )

3des算法code,已经通过visual c++编译．比一重des算法更加可靠！(3DES algorithm code, has passed visual c++ Compiler. Than one algorithm more reliable re-des!)

VB文件加密器（异或加密）,有需要的就下载吧。(VB file encryption (XOR encryption), there is a need to download it.)

信息加密原码，用md5算法实现，开发语言：c(original message encryption code used md5 algorithm, the development of language : c)
