Croatian Developers Create Add-On for Facebook Messenger and Win Global Competition

Total Croatia News

Another major success for Croatian developers.

Croatian developers have won the CopenHacks competition held over the weekend in the Danish capital Copenhagen, defeating 25 teams from the United States, Russia, India, China, Greece, Denmark, Iceland and many other countries, reports on April 19, 2016.

Members of the Croatian team were Marko Božac, an economics student currently living in the United Kingdom, Stanko Krtalić Rusendić and Petar Šegina, students of the Faculty of Electrical Engineering in Zagreb, and, Luka Strižić, who is currently enrolled at the Spacemaster studies in Sweden.

“We have built an extension for the browser which adds an unobtrusive end-to-end encryption for the Facebook Messenger”, said Luka Strižić and added: “In short, using this system, you can continue to use Messenger as you had used it before, only now no one can read the messages except the people included in the communication. That includes Facebook itself, even though the communication is going through their servers. All others who would want to intercept the communication can only see a seemingly random sequence of letters. Encryption and decryption is done by GNU Privacy Guard, which is relied on by users and systems from around the world.”

The members of the Croatian team decided to try to implement this particular project just one day before the competition began. Although, as they complained, they had only five minutes to present their project, which was certainly not enough, members of the jury recognized the value of their work and declared them champions of the competition.

The event, which lasted continuously for 24 hours, was held as part of the official student hacking league (Major League Hacking), sponsored by Microsoft, Amazon, Bloomberg and other large IT companies.
