DES算法实现过程分析

WTLS安全层源程序-WTLS layer security source

base64 算法，这是一个非常详细的编码和解码的过程-base64 algorithm, this is a very detailed process of encoding and decoding

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.

JAVA开发的，使用RSA,MD5开发的简单数字签名软件，可以用来对文件和消息做数字签名。 -JAVA development, the use of RSA, MD5 developed a simple digital signature software, can be used for documents and information to do a digital signature.

其实网上这方面的代码已经不少了,但是大多都如出一辙,主要是给出的代码不但不好理解(主要是为了处理大文件,支持分块,这样就会屑弱初学者对算法的理解),该源代码在引入必要头文件后可以在VC6.0下顺利通过编译-fact that the Internet has been a lot of code, but most of all the same, given the code is not only poor understanding (mainly to handle large files, support block, which would litter beginners weak understanding of the algorithm), the source code necessary to the introduction of the first document in VC6 .0 smoothly through the compiler

Introduction to Cryptography in plain simple english. The document talks about the early day cryptography and gives some simple examples to the readers.

在网络上销售的商业管理系统，一般都要注册才能使用。本实例将使用INT文件对软件进行用户信息注册。-On the network marketing business management systems, generally have to register to use. INT files in this instance will use the software user information registration.
