Projects list: 1. Registrar Engine (In Progress)Provide domain name registrars with API to interact with registries. The API should provide single access point for the registrars for numerous registries. It takes into account different extensions to the EPP protocol which registries provide to ease the development of the software for registrars. The application is multilayer and multitier. The implementation of single API performs calls for different external services. These calls are distributed among servers and performed in parallel where it is possible.2. dns.com integration (Completed)Integration of our DNS system with services which DNS.com provides. The main challenge was to work with the DNS.com service in parallel but the domains with the same name should be processed in a sequence. Unfortunately it was forbidden to use TPL (task parallel library), due to restrictions on the hosted server, so the task was solved with thread pool. The application is multilevel and multitier.

Core of Protection for .NET developer.NET obfuscator developerWeb-Site developerProject coordinator-----------------------------------------------------Part 1 (Completed): Software extracts the code parts from the PE executable and encrypts it using Blowfish/448 and RSA algorithms. During the execution of the managed file, JIT is hooked. When the method is requested for compilation the saved method body is decrypted and provided to the compiler. Some additional protection techniques are used. Also software package has its API, which software developer can use to interact with the protection. API implemented in native part. Managed API stubs are hooked and the call is forwarded to the native implementation.Part 2 (In progress): Provide advanced obfuscation means to the developer. Add scrambling, code control flow obfuscation, strings encryption, etc.
