高分跪求DES加密的activeX控件，有的请提供(300)

高分跪求DES加密的activeX控件，有的请提供OCX文件，和控件的使用函数，最好提供一个加解密的例子。

给你个DES加密的单元源文件,我一直在用的用法很简单,调用两个函数就可以了.AKey可以你自已随便定义,解密时一致就可以了.function DESEnCrypt(AText: string;
AKey: string = 'ILoveYouMyBaby'): string;function DESDeCrypt(AText: string;
AKey: string = 'ILoveYouMyBaby'): string;//以下是单元源文件unit MyUnitDESCrypt;{******************************************************************************* * ** DES EnCrypt & DeCrypt ** ** this Unit include two functions: ** ** DES EnCrypt: use function DESEncrypt() ** DES DeCrypt: use function DESDeCrypt() ** ** the function has two params: ** ** First Param AText is the string what you want to EnErypt or DeCrypt ** and Second AKey is then
Key Value ** ********************************************************************************}interfaceuses SysUtils;function DESEnCrypt(AText: string;

谢谢djrj的,不过我再问个问题,你一般是做成DLL文件还是OCX文件,我只做过DLL,没做过OCX,你做过吗,如果做过,留下你的QQ号交流一下

为什么要做成OCX呢，供其它语言调用吗？

是呀，为什么要做成ActiveX呢？是在IE中用吗？ActiveX不是很难的东西，只是你的ActiveX在IE中需要安全方面的考虑，IE不让你用，想用就要交注册费。但是可以使用其他IE内核的浏览器使用。

这主要是客户的要求,只有做OCX了,我没做过这东西,郁闷得很

luoyanqing119说对了,我估计也是

客户要求你做OCX？他要求还真高，你可以逗他，做成DLL，把文件扩展名更改为OCX，呵呵，反正代码又不给他们。

D7中，1>菜单 File/New/Other 弹出界面2>选择 ActiveX页面中的ActiveXControl，确定 （弹出新界面）3>VCL ClassName 中，选择TButton，其它默认，确定，之后估计要等待20秒4>现在编译，可以产生ButtonXControl.OCX文件了，5>选择ButtonXControl_TLB单元，按F12,把你不需要的函数、属性删除（在第三级节点中），注意第二级节点别删除哦。6>随便增加一个函数试试，然后编译，重新生成OCX文件。7>保存、关闭本工程文件。8>菜单: Component/Import activeX Control（出现对话框）9>Add 你刚才的OCX文件，然后执行Install按钮，按默认操作一直执行下去10>编译 Dclusr.dpk（应该会自动打开这个文件），可能需要点一下Install按钮。11》在ActiveX页面上，你可以看到你刚才的那个控件了。12>关闭所有工程文件，新建一个application13》放一个你刚才新建的activex控件，看看是否可以调用你步骤6中增加的函数。以上为一个测试步骤，等熟悉了，你可以在步骤6中，把不需要的默认的函数、属性统统删除掉。

楼上的是想利用DELPHI的VCL转OCX的向导，在转化过程中进行修改

是啊，从简单到复杂，做OCX从这里开始学着做，比较容易学，也比较容易理解，等完全理解了，他就可以不用向导了。算法部分，djrj说的很清楚了。

谢谢大家,消化一下在问各位

试出来了,谢谢各位[][][]
