在Delphi开发快速CRC算法。

CRC校验程序，使用了CRC-16和CRC-CCITT方法 -CRC inspection program, which use crc-16 and crc-ccitt method

使用C编写的DES, DESX, DES3(三层DES) 的加密算法, 本程序演示如何在Delphi中进行调用C编写的算法 DES 密匙长度 8 DESX 密匙长度 16 DES3 密匙长度 24 (加密强度高了很多)-C prepared by the use of DES, DESX, DES3 (three-DES) encryption algorithm, the program demonstrates how to call in Delphi in the preparation of the algorithm C key length DES key 8 DESX length 16 DES3 key length 24 (high strength encryption a lot)

BASE64编码的C实现，很精简，可以直接内嵌入工程-BASE64-coded C implementation, it is streamlined and can be directly embedded engineering

des算法，用vc++写出来的，密码学实验写的程序-des algorithm

大数计算在公钥加密中起到了重要的作用，如何操作大数呢，该程序也许能帮你解决这个问题有所帮助。-calculated in the end, the public key encryption plays an important role in the operation of large numbers do, the program may be able to help you resolve this problem some help.

EXELOCK 1.83 EXE文件加密器的源代码-EXELOCK 1.83 EXE file encryption for the source code

md5是常用的加密算法，但是在vc中没有系统的类可以用。本程序完成了md5类，使用简单。不是国内网上流传的类。-md5 is a commonly used encryption algorithm, but in vc no class system can be used. This procedure was completed md5 categories, using a simple. Rather than domestic circulating online class.

对ORCLE数据库进行保护，具有很强的功能，有加密，访问，删除，等保护功能-right ORCLE database protection, and highly functional, encryption, access, deletion, such as the protection function

在一个exe文件后面加上一个节，并设置密码，运行的时候需要输入密码才可以执行-in an exe file, insert a section, and set the password, Operation of the need to enter the password before they can implement
