AppFuscator is a cloud — based protection .NET

Hello Habr! We successfully worked on our product, and today I want to share the news. For those who have not read the previous topics (1 and 2), let me remind you that we are developing an online service for protection .NET applications. The process of obfuscation takes place directly in the cloud via SaaS.

Tell us a little about innovation.

the client Program


For those who obfuscate their programs constantly we have simplified the process — now You can use a special a client to work with our service. The configuration can be saved to a project, and then to obfuscate Your programs in one click.

program obfuscation C#

The program is distributed as open Source (MIT license), everyone can find source. In the future, we plan to put the API in a separate module for easy integration with other programs.

The program is still a beta, we apologize in advance for any bugs.

Control flow obfuscation


In AppFuscator added a new protection algorithm of Control flow obfuscation — obfuscating control flow. The essence of this method is to separate the design into individual components and building from them is difficult-associated transition graph. In the end, the logic of the code to understand to become very not easy.

A small example:

Full code obfuscating method can be viewed here (I've turned off all protection except for Control flow obfuscation)

Features:

  • Several different ways of switching between units

  • Support for Switch instructions
    • the
  • Dynamic counters to indicate the status between units

Summary: return the decoder to write perhaps, but it is not quite easy, expensive and difficult. Will have to sharpen it individually for our algorithm, and we will try to update frequently, so the potential hacker was fun and eventful.

Improved WPF obfuscator


Significantly improved algorithms of obfuscation WPF. Our obfuscator can rename the objects used in XAML markup, and thus correctly handles Bingings, Attached Properties, Attached Events, and other crafty designs from the world of WPF. Typically, the process of obfuscation does not require manual configuration, will take care of everything intelligent algorithms analyze code and XAML markup (more precisely, BAML).

Personal account


Now, every user can personal account. It is possible to see the history of obfuscate and download the previous version obfuscated to explore MAP files.

Vkontakte sync with address book for iPhone. How it was done

Изображение
the Background application on androidphone when you install the application Vkontakte is possible to use it as a provider of contacts to synchronize the contacts from Facebook with contacts in your address book. In this case stretches the avatar, date of birth, address, phone numbers, etc. When I after prolonged use HTC Wildfire S rated and are so used to this that he wanted to find a similar to the iPhone. Not found, so we took it and made his own — Synchronizer VKontakte :) It was back in November of last year. The application was done fairly quickly — it uses quite a few functions of Vkontakte API and functionality with the address book of the iPhone. But when we started to deal with the automatic matching of contacts, it was fun. Compare head-on by name, last name and phone number was easy to do, easy, and worked through it quickly. But found only 20 percent of coincidences of the contacts from what is provider in Android. Of course, only direct hits do not sui

Automatically create Liquibase migrations for PostgreSQL

Изображение
Working with Liquibase always brings confidence in the fact that the database objects are in the same condition in which you want it. It is this confidence and makes system migrations so popular databases. Today I want to tell you how to make using liquibase a bit easier. If you write a migration by hand, and your target database is PostgreSQL, then read this article, I am sure, the time spent on reading the article will be repaid with interest. I hope you already know how to work with Liquibase, so only two words describe how the system works. In order to make changes in the database, you need to create a migration file (changeset) that you need to specify in the file change log (changelog), after which the migration can be successfully applied to the target database. Undeniable and obvious benefit of this approach is the ability to rollback the changes. In my opinion, liquibase, there is only one drawback — the automatic rollback of changes only works only if the mi

What part of the archived web

Изображение
/ > the time Machine Internet Archive is the largest and well-known archive that preserves web pages since 1995. Besides him there are a dozen other services, which are also archived to the web: the indexes of search engines and industry-specific archives like Archive-It , UK Web Archive , Cite Web , ArchiefWeb , Diigo . Interesting to know how many web pages gets into these files, relative to the total number of documents in the Internet? It is known that the base of the Internet Archive for 2011 contains more than 2.7 billion URIs , many of them in multiple copies taken at different points in time. For example, the home page of Habra "photographed" already 518 times since July 3, 2006 . It is also known that the base reference Google five years ago overstepped the mark in trillion unique URLS , although many of the documents were duplicated. Google is not able to perform all URLS, so the company decided to count the number of documents in the Internet a
