PassCypher NFC HSM and PassCypher Pro NFC HSM: Secure and Convenient Password Management Introduction PassCypher offers a range of contactless hardware password managers known as PassCypher NFC HSM and PassCypher Pro NFC HSM. These products are protected by three invention patents and incorporate EviPass, EviOTP, and EviCore NFC HSM technologies, along with Freemindtronic’s NFC HSM […]
PassCypher HSM protège les secrets numériques. Il protège vos secrets numériques hors du périmètre du système d’exploitation compromis. Il utilise des dispositifs NFC /HSM PGP chiffrés en AES-256 CBC. Cela garantit une protection optimale contre des attaques avancées comme CVE-2023-32784, où les secrets stockés dans des fichiers mémoire comme hiberfil.sys et pagefile.sys peuvent être vulnérables […]
CVE-2023-32784 Protection with PassCypher NFC HSM safeguards your digital secrets. It protects your secrets beyond the compromised operating system perimeter by using NFC/HSM PGP devices encrypted with AES-256 CBC. This ensures optimal protection against advanced attacks like CVE-2023-32784, where secrets stored in memory files like hiberfil.sys and pagefile.sys may be vulnerable to exfiltration. Learn how […]
Whisper Leak side-channel: token-length leakage, semantic inference, and the structural limits of HTTPS in large language model (LLM) communications. This Chronicle documents how encrypted transport can still expose sufficient metadata (size, cadence, burst patterns) to infer sensitive topics and operational intent from encrypted traffic shape without breaking TLS. It explains why this is not a […]
Zero-Knowledge Downgrade Attacks: downgrade paths against Bitwarden, LastPass, and Dashlane show how cryptographic backward compatibility can structurally weaken a zero-knowledge architecture. When KDF parameters can be influenced server-side, zero-knowledge becomes conditionally vulnerable under an active compromise assumption. This dossier explains why encryption primitives are not “broken”, but why parameter governance, version discipline, and cryptographic sovereignty […]
Zero-knowledge vulnérable : les attaques par downgrade contre Bitwarden, LastPass et Dashlane révèlent comment la rétrocompatibilité cryptographique peut fragiliser une architecture zero-knowledge. Lorsque les paramètres KDF peuvent être influencés côté serveur, le modèle zero-knowledge devient potentiellement vulnérable sous hypothèse de compromission active. Ce dossier analyse pourquoi un système zero-knowledge vulnérable ne remet pas en cause […]
