A Drop-In KEM Replacement for Client Signatures in Post-Quantum SSH

The transition to post-quantum cryptography is reshaping the Secure Shell SSH protocol for remote administration. Post-quantum key exchange has been deployed in OpenSSH and is being standardized, while SSH authentication largely remains a signature-replacement effort. This path preserves the...

Astra Linux – Vulnerability in python-cryptography

In the cryptography package for Python before version 3.3.2, certain sequences of update calls to symmetrically encrypt multi-GB values could lead to integer overflows and buffer overflows, as demonstrated by the Fernet class...

Cryptocurrencies in the Quantum Age: Migration Paths to PQC

Quantum computers pose a fundamental threat to blockchain systems that rely on elliptic-curve cryptography. This work reviews the quantum vulnerabilities and associated economic risks of major blockchain platforms, with a focus on Bitcoin, Ethereum, and Solana. We distinguish between at-rest,...

quantum-security-project — Updated!

OWASP Quantum Security Project Prepare Today. Protect tomorrow. An official OWASP community project mapping the security risks of the quantum era in a practical, vendor-neutral, and risk-based way - the antidote to hype and fear. Status: Bootstrap phase. The OWASP Top 10 for Quantum Security Risk...

AI Grinding for Fun and Cryptanalysis

We present an autonomous cryptanalysis workflow in which agents generate, test, and refine hypotheses before human review. The autonomous stage returns reproducible candidates with exact witnesses, controls, code, and run records. A researcher then decides whether the evidence establishes a break...

Use of a Broken or Risky Cryptographic Algorithm

Overview Affected versions of this package are vulnerable to Use of a Broken or Risky Cryptographic Algorithm due to the extractContextHash logic in SemanticCacheAdvisor.java. An attacker can receive cached responses from an unrelated system prompt by sending requests whose prompts collide under...

Eavesdropper-Blind Remote State Preparation and Applications to Quantum Public-Key Encryption

Remote state preparation RSP is a central primitive in quantum cryptography, enabling classical parties to remotely construct quantum states using only classical communication. As a result, RSP serves as a key building block in numerous protocols involving classical clients and quantum servers,...

CVE-2026-77151 lin-snow Ech0 crypto.go MD5Encrypt risky encryption

A security flaw has been discovered in lin-snow Ech0 up to 5.4.1. Affected by this issue is the function MD5Encrypt of the file internal/util/crypto/crypto.go. Performing a manipulation results in risky cryptographic algorithm. Remote exploitation of the attack is possible. The complexity of an...

CVE-2026-77151

lin-snow Ech0 (versions up to 5.4.1 ) is affected by a cryptographic weakness in the MD5Encrypt function located in internal/util/crypto/crypto.go. The use of MD5 as a hashing algorithm is considered a risky cryptographic practice, as MD5 is known to be collision-prone and unsuitable for security...
