RSA IS NOT ALREADY SAFE.

__IT IS EXTREMELY IMPORTANT!__

Here is a slide from the **NIST** presentation on 04-11-2018. We can see that **RSA - 2048**__ has been hacked already__. Furthermore,** ****Elliptic-curve cryptography** is also based on RSA and is used in almost every messenger

Schneier on Security

Several groups are working on designing and building a quantum computer, which is fundamentally different from a classical computer. If one were built -- and we're talking science fiction here -- then it could factor numbers and solve discrete-logarithm problems very quickly. In other words, it could break all of our commonly used public-key algorithms.

NIST Post Quantum Project

In recent years, there has been a substantial amount of research on quantum computers – machines that exploit quantum mechanical phenomena to solve mathematical problems that are difficult or intractable for conventional computers. If large-scale quantum computers are ever built, they will be able to break many of the public-key cryptosystems currently in use. This would seriously compromise the confidentiality and integrity of digital communications on the Internet and elsewhere.

The National Security Agency is advising US agencies and businesses to prepare for a time in the not-too-distant future when the cryptography protecting virtually all e-mail, medical and financial records, and online transactions is rendered obsolete by quantum computing. Quantum computers have capabilities that can lay to ruin all of the public-key cryptographic systems currently in use.

The National Security Agency, too, has sounded the alarm on the risks to cybersecurity in the quantum computing age. The NSA's "

According to many experts, the NSA is far too conservative in its prediction; many experts believe that
