Is the #RSA public-key #encryption system in danger?

Can you break the RSA public-key encryption system using a quantum computer – Yes!

Researchers in China say they have reached a breakthrough in quantum computing. They claim that they have worked out how they can break the RSA public-key encryption system using a quantum computer. They used a quantum computer that  that will soon be publicly available!

Breaking 2048-bit RSA would be extremely significant. Although the RSA algorithm itself has largely been replaced in consumer-facing protocols, such as Transport Layer Security, it is still widely used in older enterprise and operational technology software and in many code-signing certificates. If a malicious adversary were able to generate these signing keys or decrypt the messages protected by RSA then that adversary would be able to snoop on internet traffic as well as potentially pass off malicious code as if it were a legitimate software update, potentially enabling them to seize control of third-party devices.

In a white paper published by the U.K.’s National Cyber Security Centre in November 2020, experts warned that because almost all of today’s widely-used public-key cryptography systems depend for their security on the difficulty of factoring very large numbers, they would be easy to crack with a large-enough general purpose quantum computer.

You need to act now!

We at IronCAP™ have been trying to educate businesses and individuals that Q-day (the day the first quantum hack is publicly recognized) is around the corner and everybody needs to gear up. Nation states and governments are already at it, how about you? To learn more, visit

IronCAP™ is our latest innovation for the post-quantum cybersecurity. This patent-protected, post-quantum cryptographic system is based on the Goppa Code-based cryptographic technology. It has embedded our proprietary subclass of (L, G) making it not only more secured but also has faster cryptographic operations (key generation, encryption, decryption) than the traditional Goppa Code-based technology (McEliece). We are offering a live demonstration for the general public to try and experience the strength of IronCAP™ post-quantum encryption easily. To learn more, visit
