- 1Cryptographer warns public key cryptography could be lost●I think we might lose public key cryptography
Cryptographer Matthew Green says he believes we might lose public key cryptography, the technology underpinning most modern digital security, from encrypted messaging to online banking. His warning, shared on social media, has drawn wide attention among security researchers and developers debating the threat, with discussion focused on what could cause such a loss and how the field could respond.
- 2Cryptographer Matthew Green warns public key cryptography could be lost●Matthew Green: "I think we might lose public key cryptography"
Johns Hopkins cryptographer Matthew Green says he thinks "we might lose public key cryptography," the mathematical foundation securing most internet communications, including HTTPS, messaging apps and digital signatures. His remark is drawing wide attention among security researchers, with debate focused on whether advances in quantum computing could eventually break the encryption the modern web depends on.

OpenAI's GPT-6, called Astra, has decrypted a 217-year-old coded letter from the Napoleonic era in about six hours from a single prompt. The system deciphered 24 rows of custom symbols from one image, revealing what are described as lost French troop orders. Commenters are debating what the feat says about AI's growing ability to solve historical cryptography problems that resisted human codebreakers for two centuries.
- 4Sharded, encrypted storage tool for friend networks over Yggdrasil●Sharded, encrypted storage between friends over Yggdrasil
A developer has released yggstore, an open-source project offering sharded, encrypted storage shared between friends over the Yggdrasil overlay network. Files are split into shards and distributed across trusted peers, with encryption protecting content and Yggdrasil providing the connectivity. Early discussion centers on the privacy-friendly design and how practical peer-to-peer storage among small trust groups can be.
- 5Veil launches zero-knowledge messenger with post-quantum encryption●Show HN: Veil – Zero-knowledge messenger with post-quantum encryption
A developer has launched Veil, a messaging app described as zero-knowledge and secured with post-quantum encryption, sharing its architecture publicly. The messaging industry is moving toward quantum-resistant cryptography ahead of future quantum computers capable of breaking current encryption, and Signal and other services have begun adding post-quantum protections. Veil's claim that even its operators cannot access message content is drawing attention and scrutiny.
- 6Concerns raised over changes to TLS certificate practices●Возвращаемся во времена, когда сайты работали без шифрования, через открытые HTTP-соединения. Надвигающийся подход к TLS
A claim circulating among tech commentators argues that upcoming changes to TLS certificate handling would effectively return the web to the era of unencrypted HTTP connections, when browser-server traffic was unprotected. The post warns that the shift could undermine the encryption baseline the internet has relied on for years, framing it as 'the coming era' of weaker web security.
- 7Signal releases iOS update with improved notification settings●Nieuwe Signal update voor iOS (8.33) 🎉 - Verbeterde meldingsinstellingen voor gedempte chats en reacties - Herinneringen
The encrypted messaging app Signal has released version 8.33 of its iOS app. The update brings improved notification settings for muted chats and reactions, plus reminders for unread messages. Dutch-language coverage from AboutSignalNL highlights the changes for iPhone users, pointing to the app's release notes for full details of what has been tweaked.
- 8Ransomware data theft surges 275 percent●https:// shattered.io/ransomware-data-t heft-surge-275-percent-2026 # Ransomware # DataBreach # CyberSecurity # ThreatIn
A new report points to a 275 percent surge in ransomware-related data theft heading into 2026, with attackers increasingly stealing data rather than only encrypting systems. Cybersecurity commentators are sharing the finding, citing Zscaler threat intelligence, as organisations brace for more double-extortion attacks.
- 9ArcaneChat pitches itself as the private family side chat▼every family chat has at least one side chat 🤫 # ArcaneChat # privacy # encryption # Europe # European # eu # family # a
ArcaneChat, an open-source encrypted messaging app, is promoting itself with a familiar joke: every family group has at least one hidden side chat. The post plugs privacy, encryption and decentralisation, targeting European users who want messaging autonomy on Android. Engagement so far is small, but the message resonates with ongoing EU debates about digital privacy and secure communications.
- 10Lattice Semiconductor Wins Award for Quantum-Proof Chips●Lattice Semiconductor Wins Cybersecurity Award For Quantum-proof Chips
Lattice Semiconductor has received a cybersecurity award recognising its quantum-proof chip technology. The company's semiconductors are designed to resist attacks from quantum computers, which could eventually break today's encryption standards. The recognition highlights growing industry focus on post-quantum security as businesses and governments prepare for future quantum threats.
