Chris<p>This is only a proof of concept cracking of a 22 bit RSA key. However it shows that the cracking of cryptographic algorithms that we are currently using require advances in technology rather than in theory or basic science. I suspect that the time we have before our current banking security is useless is a few decades, but there time before national agencies can crack messages protected by these algorithms a lot less</p><p><a href="https://www.earth.com/news/china-breaks-rsa-encryption-with-a-quantum-computer-threatening-global-data-security/" rel="nofollow noopener" target="_blank">https://www.earth.com/news/china-breaks-rsa-encryption-with-a-quantum-computer-threatening-global-data-security/</a></p><p><a class="hashtag" href="https://mitra.northumbria.me/collections/tags/cryotography" rel="nofollow noopener" target="_blank">#cryotography</a> <a class="hashtag" href="https://mitra.northumbria.me/collections/tags/quantumcomputing" rel="nofollow noopener" target="_blank">#quantumComputing</a> <a class="hashtag" href="https://mitra.northumbria.me/collections/tags/security" rel="nofollow noopener" target="_blank">#security</a> <a class="hashtag" href="https://mitra.northumbria.me/collections/tags/codebreaking" rel="nofollow noopener" target="_blank">#codebreaking</a></p>
