Although no machine today can break elliptic curve cryptography or RSA, quantum hardware is advancing rapidly and will inevitably change how organizations protect their data. Ciphertext and credentials captured by attackers can now be stored and decrypted as soon as quantum computing catches up.<\/p>\n<h2>How urgent is quantum-resistant cryptography?<\/h2>\n<p>The Global Risk Institute\u2019s 2025 Quantum Threat Timeline report shows that surveyed security specialists believe a cryptographically relevant quantum computer is likely to be available within 15 years, with 51-70% indicating so. The threat dates back to 1994, when Peter Shor proved that a powerful quantum computer could efficiently factor large numbers and compute discrete logarithms. However, Shor\u2019s algorithm applies to public-key cryptography, posing no meaningful threat to symmetric encryption like AES-256 or modern hashing. This distinction matters because public-key cryptography is what two systems use to establish trust and agree on the keys that protect their data. If a quantum computer can break that step, the attacker can unlock the protected data and credentials behind it.<\/p>\n<p>What makes the quantum threat relevant today, rather than solely in the future, is a tactic known as Harvest Now, Decrypt Later, in which an attacker captures encrypted traffic today, stores it, then decrypts it when a quantum computer is available. With a capable quantum computer plausibly available within 15 years, any data intercepted and harvested today should be treated as data already exposed.<\/p>\n<h3>Q-day deadlines<\/h3>\n<p>Even though it\u2019s unclear exactly when a quantum computer will arrive, government agencies are setting deadlines around the milestone known as Q-day for when cryptography&#8230;<\/p>\n<p><a href=\"https:\/\/thehackernews.com\/2026\/06\/why-post-quantum-cryptography-starts.html\">Source<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Why Post-Quantum Cryptography Starts With Credentials https:\/\/thehackernews.com\/2026\/06\/why-post-quantum-cryptography-starts.html Publish Date: 2026-06-29 07:45:00 Source Domain: thehackernews.com \ue804The&#8230;<\/p>\n","protected":false},"author":1,"featured_media":283586,"comment_status":"closed","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"fifu_image_url":"https:\/\/blogger.googleusercontent.com\/img\/b\/R29vZ2xl\/AVvXsEgufw7UrtG2RgRTMvdhUaNVywdIBuSIRFLngtWMIY_3fzq7gzTZnlL7KMi_kzPhfpdny4vP5Rd9QVLpkX9xR5Vpk0cVvDV8Xsy4wljRyA5TjKvojsoBsYJt7yhhk1VK46OegGewBgqi-c41Z5mX5Ivos1PMrgrrmgLZKUJ8hqb4xl8o85sB7jQJLvI3gj0\/s1600\/keeper.jpg","fifu_image_alt":"","footnotes":""},"categories":[15],"tags":[35],"class_list":["post-283585","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-cybersecurity","tag-hacker"],"_links":{"self":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/283585"}],"collection":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/comments?post=283585"}],"version-history":[{"count":1,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/283585\/revisions"}],"predecessor-version":[{"id":283587,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/283585\/revisions\/283587"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/media\/283586"}],"wp:attachment":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/media?parent=283585"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/categories?post=283585"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/tags?post=283585"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
