这是一个VB制作的简单加解密演示，利用字符的Asc码加上偏移量进行加解密，处理结果可逆，进行灵活的代码扩展可以获得更高的加密强度，对一些加密要求不高的程序，这是是一种不错的加解密选择。-This is a VB produced by the simple encryption and decryption demonstration by Asc character code plus the offset encryption and decryption processing result reversible, flexible code extension can achieve higher encryption strength, less demanding for some encryption program this is a good choice of encryption and decryption.
