This website is moved from http://www.geocities.com/hmaxf_urlcr, the reason is because Yahoo decided to close GeoCities on 26th October 2009. All information in this site is OUTDATED (including my personal detail) and still exist only because I want to keep my old work / research history.

Please be well-informed before using any information from this VERY OLD page, I do not take any responsibility for any kind of loss due to usage of invalid and outdated data from this site.

21st June 2003
Some of VB developers asked me how to use the RSA DLL in VB, now I've finally decided to upload the old source code, please download the updated RSA GUI in VB plus its source code in tools section. Enjoy the source code and I believe many of you can improve it so improve it and share it.

I also made another upload which is the most important of all upload so far, yes I have uploaded the HMaxF_URLCR compression tool source code in VB of course, why I do this now ? well, people have asked me many times about why I dont want to share the source code and people will ask me again later for it, the answer is NOT I am worry about people stealing the idea in that source code, because there is nothing special in that source code other than fancy GUI and some small tricks, I did not upload it because it have not finish yet, but time is running so fast and still I have not been able to finish it, I asked myself sometime,"what is my definition of finished?" well, I got tired for answering that question myself, now I have upload it and share it with everybody, please enjoy it, improve it and share it with everybody, and also of course, tell me if you have improve it or you have further question about it, I hope I am doing the right thing.

I am back .. ;p ..
A long holiday indeed, I am sorry for the lack of update to this web site, I have been so busy keeping my life and my family, but I've done my homework, I hope everyone happy with my e-mail reply to them, I ALWAYS hope I can be a help for the novice in lossless compression and security. I have wrote some articles which are overdue, please check the articles, I put some number theory articles, these information related to prime number which are used in security such as in RSA, Diffie-Hellman, etc. These articles can be found widely on the net but I put my own version just to fill up my web site and to greet all of you visitors, thanks for all your supports and your e-mail I will keep updating my web site and I will put the also long overdue big number calculator, yes, it is 128-bit calculator with some extra functions.

About lossless compression, I am still searching a way to transform an incompressible value into more useful and compressible value. The thing is, there is no one algorithm can fit all situations, so I keep looking and trying to find the better algorithm.

Like always, people please don't be hesitate to e-mail me regarding these subjects, I love to receive your e-mail and I will always reply them on time.

Lastly, anyone can help me to find a space which I can put a board/discussion, so we all can exchange ideas more quickly, if you can help me please contact me also if there is anyone want to put some articles in this web site, please do contact me, I will be pleased to read your article and put it here.

9th March 2002
I want to share this site with other people who are interested in security(encryption) and compression, I will put any article here if I found it not offensive and good, so please don't be hesitate to e-mail me and sending me any article which you think I should put here, I am doing this because this site (geocities) not allow me to run message board.

8th March 2002
No update no new software, just want to comment about C#, I have been playing with C# (release version, not beta), C# is very clean, easy to use, I must say that it even easier than VB, but it might because the amount of time I spend for it, the bad news is .NET framework (run time) is required to run any application created in C# and other .NET languages, it is not only because the run time size (around 20MB, current release) but because I feel the application is quite slow to run, the translation to the native machine language consumes an unbearable lengthy time even for 1Ghz CPU with 256 MB RAM, I just can hope that someday, someone can make the application created .NET can run without .NET framework and run as fast as C/C++. I also want to thanks to everyone who emailed me, giving suggestion, question and sharing, also I am sorry for the late reply because I am busy of my work and life, I try to reply as soon as I can.

13th February 2002
A long time since I update the web site, I would like to thank to everyone who emailed me regarding everything about this site subject. An updated RSA 2048-bits dos source code is uploaded, also I am working on a new GUI for the RSA, the old one is created in VB, it does not have multithread function, so I will create a better GUI. Another update that I should have mention earlier is that actually the RLE source code in C/C++ is downloadable.

17th November 01
RNG is updated, and also I would like to mention that in RSA source code there is a module for base64 (MIME / PEM) encoder/decoder, so if anyone would like the module you can download the RSA source code and get the rsa_pem.c which has the base64 module.

13th November 01
The UI for RSA is done, download it here, also fixed silly bug.

9th November 01
RSA library is updated, please report any bug found, BIGNUM module optimazation is very welcome.

8th November 01
The RSA article is updated and RSA library (C/C++ code) is uploaded, this is the first version, I will update it as I progressing, if you found any bug please report it to me. It has no UI, the UI is on the way.

30th October 01
Preliminary library (program) for RSA is done, improvement is being made, also the UI in Visual Basic is underway, RSA article will be updated for more information, and I am sorry to mention that the RSA library is based on OpenSSL Big Number module, the RSA module is my code, it is small, I only need the Big Number module because it is the most important part in public key cryptography, I am still improving the BN module, hoping that I could find a better algorithm or maybe just simply cleaning up the BN module code so it can be more understandable and faster, I hope. The BN module is really important as it can be use for other public key cryptography such as Eliptic Curve Cryptography (ECC), Diffe Helman key exchange and many other.

17th October 01
The RSA articles is up, I am still testing the RSA library, so bear with me for a while and expect the library to be here soon, the library is FREE, it is the real RSA library.

15th October 01
It has been long time since I update my web site, I have been desperately looking for a space to put my cryptography documents, finally I decided to put my cryptography work in this very same site, I will change the logo of this site soon, any suggestion is welcome, I also have been developing the library for RSA, it is quite done, I will put it here along with the articles I created one by one soon.

12th August 01
VBANSIString demo program is created plus a minor modification (optimization is done)

11th August 01
Compression as the best way to encrypt data is updated.

9th July 01
Updated HMaxF URLCR Tools, the StoreXValue module is updated, the result is smaller, currently only on separator, the other module will updated soon.

3rd July 01
This site is under construction, if there is any broken link or maybe incorrect content, please report to me

27th June 01
Updated an article which quite been a debate, Compression as the best way to encrypt data

26th June 01
Random Data Compression and Recursive Compression and Sort and Swap are updated.

25th June 01
HMaxF_URLCR_Tool is updated with some bug fixed and one module is added. Have fun compressing your file.

21st June 01
Some people ask and wonder what is actually my project and what is the method. So I think I better explain it in detail, it is Grouping method, please read it and contact me again if still confused.
