源代码保护方面其实现在考虑得没那么多了..NET也可以反编译.ASP写得复杂的话别人能看得懂的话.他也有能力自己写了.这方面担心的倒不太多.纵观现在网上可以下载的那些所谓BBS还有什么网站等等的源代码xbmXBM图片是一个纯文本的文件,能够用ASP来主动天生。能够用它来利用网站上岸的考证码;
我们用记事本翻开该文件举行剖析:
其文件布局为:
#definecounter_width48
#definecounter_height9
staticunsignedcharcounter_bits[]={7c,3c,7c,3c,70,3c,fe,7c,fe,7c,78,7c,ee,ee,ee,ee,7c,ee,e0,ee,60,ee,74,ee,70,fe,30,fe,70,fe,38,ec,e0,ec,70,ec,1c,e0,ee,e0,70,e0,fe,7e,fe,7e,70,7e,fe,3c,7c,3c,70,3c}
文件扩大名为:.xbm
#definecounter_width48这儿界说的是图片的宽度,通常是8的倍数
#definecounter_height9这儿界说的是图片的高度,是恣意的。
staticunsignedcharcounter_bits[]={7c,3c,7c,3c,70,3c,fe,7c,fe,7c,78,7c,ee,ee,ee,ee,7c,ee,e0,ee,60,ee,74,ee,70,fe,30,fe,70,fe,38,ec,e0,ec,70,ec,1c,e0,ee,e0,70,e0,fe,7e,fe,7e,70,7e,fe,3c,7c,3c,70,3c}这儿是图片用来显现内容的十六进制的代码
正如staticunsignedchar英辞意思为静态的,无标记的,烧焦的。它只能用来显现口角两种色彩。二进制中的1未来用显现为玄色,0为红色。
上面为0~9数字的二进制数组(个中的图片款式仅试用于本例。假如必要其余0~9数字款式,请另自行天生)
此处声明0~9画图用数组
