They claim that their VyprVPN is currently safe from being breached, and that they will continue to update their systems to ensure sound encryption in the future.
Tech In Asia notes that Astrill uses the same 1024-bit RSA key encryption, despite the fact that a 2048-bit RSA key is recommended to elude potential snoopers, according to the standards of "governmental, academic, and private organizations providing guidance on cryptographic security," as stated by Bevand.įor perspective, Google made the switch to 2048-bit encryption over two years ago.Īs for other VPNs, Golden Frog confirms a prediction made in 2003, which stated that 1024-bit keys were likely to be crackable by 2010.
Using a virtual private network (VPN), as most of us do, creates a certain illusion that you're online activities are being encrypted and re-routed through servers in other countries, and is thus safe from government watchdogs.īevand, who is currently traveling the world and testing various VPNs, used ExpressVPN while in China, which although allowing him to jump the Great Firewall, only uses a 1024-bit RSA key to encrypt data through connections. While that might not mean much to many of you (or me until I started doing this research), 1024-bit is a weak encryption, and one that the government may have already cracked, garnering unlimited access to all the puppies and kittens you spend your days looking at. Following a blog post written by Marc Bevand, multiple platforms have been calling into question the safety of VPN usage in China, especially two of the most popular, ExpressVPN and Astrill.
