思考中、、、
 
这里除了付值就是循环,等我下周修改好!
 
是的,没有定义很复杂的结构类型,也没有调用API,所以从转换的角度看可能不太难,不过
由于它是一个算法,有一点点转换错误,程序能正常运行,不过结果肯定不对了。
 
做成DLL再调用不是简单方便吗?
 
行行好拉,vcl.vclxx.or上面大把这种控件
 
MD4 DES 都是极经典的算法,网上很多源码,你去搜索来看看吧!
 
我不需要控件!如果要控件的话,我有一个cipher,什么加密方式都有。
我要的是上面两个C程序的DELPHI写法。
 
是Pascal或者Delphi写的源码!最差也有DLL!
如果你不是打算做加密算法大师的话,建议不要去死扣这些,了解大概原理即可!
闻道有先后,术业有专攻。把精力花在更值更容易出成绩的地方!
 
我并不是要研究加密方法。只是在做一个控件,里面涉及到了MD4和DES加密。如果在做的
控件中去使用另外一个控件,这样很不独立。
 
自己转一下好了,我不相信你不会,干嘛指望别人帮你打下手呢?
 
如果转换很顺利,也不会叫大家帮忙了。C放下有好些时候了。另外,怎么叫“打下手”呢?
我看大富翁上好多人都喜欢贴人家的代码,能做实事的有多少呢?不过贴代码也是好事,
帮了别人的忙了。而现在有一个动手的机会,每个人又说,到那里去找一找,或什么的。
可能有些人不屑一顾,可如果自己动手去做的时候,肯定不会很顺利的。
 
说的好,但是实践起来可能会有问题了。要转换的话,是有很大难度的,不过你完全可以
按新的来做呀。
 
抄了段DES,希望有所启发。

Organization: Delft University of Technology

Source for doing DES encryption/decryption in Pascal.

This procedure uses 4 parameters :

Input : 8 byte (64 bit) input
Output : 8 byte (64 bit) output from DES algorithm
Key : 8 byte (64 bit) key for DES algorithm
Encrypt : True to encrypt, False to decrypt

The procedure uses typeless parameters so you can use variables of
any type for Input, Output and the Key, as long as they are 8 bytes
long (or more).
