Hello , my name is Dmitry Basko. I work as a software programmer and have experience in WIN32 system/application programming, smartcard technology, data and copy protection, device driver development. In past I worked as electronics engireer and familiar with programming of MCU, computer harware and its peripherals. I worked in Russia, Belarus, Germany. I decided to share my modest experience with other developers who are interesting in it. The following projects are available: PC/SC driver, VxD (simulator of secure token), GINA library, PKCS#11 library,WDM driver for PnP serial port (RS232) based device, library for decoding DER encoded X509 certificates, implementation of DES (56 bits) for 8 bits microcontroller and etc. Each time when I started a new complicated project, which I could not understand myself (at least from the beginning) I always tried to find someone, who could give me a hint, how it should be done. Really, sometimes it is not enough only reading standards and MSDN; it will help you only partly. Perhaps you will be able to convert the obtained knowledge from these sources in to the real implementation, but it can be a very time consuming process in comparison with another way, the way when you can ask somebody, more experienced about small assistance and explanations of the most important ideas for the project. And I was lucky - I could always find such people. It is a pity, I cannot remember all their names, but anyway I am very grateful for their help. Now I hope I can be useful for others.

Sometimes it is not possible to publish the source code of the certain projects - it is normal, because this code is a part of commercial products and such publications could bring harm to my former or current employer. Sometimes it is possible, because this source code shows only the main idea of the project and does not contain any company (employer) specific features and implementations. In this case, the publishing is safe and at the same time, this information can be useful for other developers.

It was a way how I created PC/SC compatible driver - a guy from Belgium described for me the mainstream of this project and it was enough for me to understand how could be done the certain implementation of this project.

There is no doubt that it is possible to find in the Internet information almost about everything, but sometimes I met exceptions from this rule. Once, I was interested in obtaining knowledge about development of PnP (Plug and Play) compatible peripheral devices. I was quite surprised than I could find almost nothing. Only a little bit information from Microsoft (certain specifications). Anyway, later a got all necessary information with help of another developer, but this case proved me still one time, that it is a very important to share knowledge and experience with others. This is a reason, why I am going to use GNU GPL (General Public License) , where it is applicable or relase projects into public domain.

The preparation of all projects to be published definitely takes some time; I will try to lay out my projects gradually. Let's finish at this place.
