LZ77压缩/解压缩算法

AES加密软件，用于加密当前文本框中的内容。使用的是美国国家标准（也被ISO所采纳）最新加密算法AES。-AES encryption software, encryption for the current contents of the text box. The use of the American National Standards (also adopted by the ISO) the latest encryption algorithm AES.

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)

数据库安全至关重要，尤其是Access数据库，由于其加密算法过于简单，使得Access单靠密码无法保证其安全，本代码通过改变数据库头文件实现对Acess数据库的加密。-Database security is crucial, especially the Access database, because of its too simple encryption algorithm, making Access a password alone can not guarantee their safety, the code by changing the header file database achieve Acess database encryption.
