Westphal!

I found some! Yes! I was searching for information of internet components and this page also had some encryption codes! Here is a page snippet :

This library contains the following algorithms:

Crypto library (formerly by CryptoCard Corp.)

MD5
RC4
RC5
IDEA
BLOWFISH
DES

BUT ALSO!

Cryptlib encryption library by Peter Gutmann, Eric Young, and Colin Plumb

The library contains the following conventional encryption algorithms:

DES
Triple DES
IDEA
MDC/SHS
RC2
RC4
RC5
SAFER
SAFER-SK
Blowfish
Blowfish-SK
The library contains the following hash algorithms:

MD2
MD4
MD5
RIPEMD-160
SHA
The library contains the following public-key encryption algorithms:

Diffie-Hellman  !!!!!!!!!!!!!!
DSA
RSA             !!!!!!!!!!!!!!

Thanks kjteng,
but i found  only a code for caclculating modulo multiplications, but still it's already good !

there are some things on the net for delphi but all of it are shareware.

for instance :

 good site : http://members.xoom.com/TSMInc/index.html

why not going to the rsa link itself? : http://www.rsa.com/

Sorry, i already saw TSM inc but they do not have RSA or other yet.

I already have the algorythm but i expected to not have to implement it ;^)

correct RSA isn't implemented yet.

source codes, C/C++ : http://ds.dial.pipex.com/george.barwood/crypto.htm
http://www.reapertech.com/RSAEuro/rsadown.html

this library has an RSA encryption, but it's expensive and I wouldn't buy it if it was only for this tool. Maybe you can make a deal with the authors?

Well, in fact i already have an RSA implementation in C (provided with SSLAY) for free. But i was looking for it in pascal: it's not always easy to link CLibrary.obj in delphi project. But still thank you for your responses.

The component at http://www.hallogram.com/xtools/features.html616 is for Delphi, forgot to mention it.

the cryptlib page url seemed to be wrong in the page I refered you to, but :

Look first at : http://members.xoom.com/bgclarke/swcrypto.html

then at :

It has to be http://www.cs.auckland.ac.nz/~pgut001/cryptlib/

Great links on this page too.

and get your cryptlib.pas at
ftp://ftp.franken.de/pub/crypt/cryptlib/beta/

Hope this is what you need.

westphal, and can you do something with it?

Sorry for this long time response, but i was sinking under other projects.

I allready had the urls you gave but finally TSM release a beta version of an RSA component...
