VB_CalculateMD5_UseWinAPI

身份证15位转18位的算法原码，可以自动将转换后的结果放入剪贴板中(Algorithm of the original code ID card 15 turn 18, you can automatically converted into the clipboard)

VC++下MD5运行和使用示例,可以正常使用MD5算法(VC MD5)

自己写的一份RSA算法。可正常执行。控制台程序。(Write your own copy of the RSA algorithm. Can be performed normally. Console program.)

讲述des加密过程，实现了简易锝des加密算法(About the des encryption process to achieve a simple encryption algorithm technetium des)

加密文件夹,十分好用 使用visual basic环境编程(lock file)

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. )

加密程序,很好用。亲自验证，完全正确。希望下载。(we can add and unadd a picture correctly.welcom to download.)

说明：  vb 加密解密程序 动态加密使用非常方便...(vb encryption and decryption process is very convenient to use dynamic encryption ...)

sha256的签名算法，纯C实现，已验证正确，在控制台上直接运行即可，(sha256 signature algorithm, pure C implementation ，has been verified properly and can be run directly on the console.)

壳代码，对于学习壳编写的同学具有一定的参考价值，绝对经典(Shell code, written for students to learn the shell has a certain reference value, an absolute classic)
