Hi Linomar!
I took a look at this library and I'm afraid you can't use it in Delphi
directly. It has no exported functions nor it is a COM-Object, so I
wouldn't know how to interact with it in Delphi. I think it's a dll
specific to ms c++.(Everybody may feel invited to correct me if I'm wrong)
If You want to use functions provided by cryptopp in Delphi you need to
write a wrapper to a more common interface, e.g. old standard dll or
COM. If you just need a few functions you should maybe try the first
approach. Build functions in C that perform the tasks you need directly
accessing cryptopp and export them in a classic dll (you should find
hints about how to write dll's with MS VC in the internet). In Delphi
you just call this functions. This is easy: You just create a unit, and
declare the functions/procedures. In the Implementation part it looks
like this:
function StartDB(Path: pchar): boolean; external 'MapLib.dll'; cdecl;
Take care of memory Handling!
The second approach(using COM) allows a more generic and comfortable
interface, but you'll need a profound experience with COM, ATL and C++
to do this.
Sorry I don't have better news!

Hi Sven,
I'm sending you the dll file that I have. This file I have compiled in
Visual C 6.0 with the source files that I found in
http://www.eskimo.com/~weidai/cryptlib.html
Why do you think I won't be able to use this dll with Delphi? Do I
have to pass an object as parameter to the functions of this dll?
Unfortunately I can't use DCPCrypt because it doesn't have the RSA
algorithm.
Thanks for your help.

I'm not sure if this works at all... afaics Cryptopp is strictly oo
c++ and not classic simple function call. I don't know if this is in
any form compatible to delphi. But if you send me the compiled dll I
might have a look.
I would suggest to have a look at Delphi-specific Components, e.g.
DCPCrypt.
