含有rc2、rc4、rc5、rc6算法的rc算法集合- Includes rc2, rc4, rc5, rc6 the algorithm rc algorithm gathers

使用的是BCB5开发的一个简单的3DES的DEMO，对文件采用的是密文挪用来处理短块。-Using BCB5 developed a simple 3DES of DEMO, the document is used ciphertext diverted to deal with the short block.

修正了原CMd5类的CaculateStr函数的严重错误，并且转到新的C++类库。此类已经经过验证，文件和字符串均能得到正确结果，支持Unicode（Unicode时不需要转换）-amendment of the original CMd5 CaculateStr function of the type of serious errors and to the new C Class. Such has been validated, documents, and the string to get the correct result, Unicode support (Unicode does not need conversion)

说明：  基于MD5的文件完整性检测程序，共包含4个文件：md5.h、md5.cpp、test.cpp、nankai.txt。编译：命令行模式下，切换到代码所在目录，输入make后回车即可。(The file integrity testing program based on MD5 contains 4 files: md5.h, md5.cpp, test.cpp, nankai.txt. Compile: In the command line mode, switch to the directory where the code is located, enter make, and press Enter.)

说明：  使用openssl实现了文件保险箱，在VC6环境下编译通过。(The use of a document openssl safe, in the circumstances VC6 compiled through.)

实现维吉尼亚密码，用键盘接收明文和密钥，屏幕打印密文。-The achievement of Virginia password, use the keyboard to receive explicit and key, screen printing ciphertext.

cryptoboot is set of tools for disk encryption on Unix. It is especially suited to encrypt root partition, so _everything_ (except kernel and cryptoboot inself) is encrypted. -cryptoboot is set of tools for disk encrypt ion on Unix. It is especially suited to encrypt r oot partition. so _everything_ (except kernel and cryptoboot inself) is encrypted.

公钥加密程序，采用非对称密钥，这里以类的形式调用-Public key encryption procedures, the use of non-symmetric key, where to type the form of call

基本的DES加密算法，可以实现一些基本的功能，但是大型计算不适合(The basic DES encryption algorithm)

用c++实现Rabin算法的加密和解密，大素数由程序自动生成(Using c++ to realize encryption and decryption of Rabin algorithm, large prime number is automatically generated by program.)
