From the site:
"In recent years, “Quantum Computers” have become visible on the horizon as we look towards the future ‒ computers so powerful they could break any current cryptographic standard. Standards that ensure the safety of our online banking or the authenticity of a website pretending to be the BBC, the Reuters news bureau or your favorite low-cost airline.
Rosenpass is an important precaution against what is to come: a safeguard. It is a computer programme installed and run in parallel to WireGuard, making it immune to attacks from Quantum Computers. Rosenpass doesn’t change the way WireGuard works (in fact, WireGuard encryption continues to work as it used to without Rosenguard), but it adds encryption that cannot be broken by the Quantum Computers that are about to become part of our online reality.
Rosenpass is Free and Open Source Software, developed independently by cryptographers and scientists with the help of a grant by the Dutch philanthropic foundation Stichtig NLnet."
