A blog post analyzing Anthropic's recent LLM-assisted cryptanalytic attacks on HAWK and reduced-round AES, arguing that LLMs will not break established symmetric cryptographic schemes.
Anthropic's unreleased Claude Mythos Preview model discovered novel attacks on the HAWK post-quantum signature scheme and a reduced-round AES variant, significantly reducing attack costs and potentially impacting standardization.
Anthropic published two cryptanalysis papers using its unreleased Claude Mythos model, attacking the HAWK signature scheme and reduced-round AES, highlighting AI's ability to combine existing cryptographic tools effectively.
OpenSSH 10.4 was released on 2026-07-06, including security fixes and experimental support for a composite post-quantum signature scheme combining ML-DSA 44 and Ed25519.
OpenSSH 10.4/10.4p1 released with security fixes and experimental post-quantum signature support.
Autocrypt v2 introduces post-quantum encryption and reliable deletion for decentralized messaging, using hybrid ML-KEM-768 and X25519 keys with automatic key rotation and destruction.
Let's Encrypt announces plans to adopt Merkle Tree Certificates for post-quantum authentication, addressing the growing urgency to migrate to post-quantum signatures in the Web PKI.
wolfSSL has released wolfCOSE, a zero-allocation C library implementing CBOR and COSE with post-quantum signing support (ML-DSA) and a tiny footprint, targeting embedded systems.
Coldkey is a command-line tool that generates post-quantum age encryption keys and creates printable HTML backups with QR codes for secure offline storage.
The article discusses the current state of the FN-DSA post-quantum signature standard, its standardization delays, and essential caveats for deployment, including prehashing considerations.
An analysis clarifies that quantum computers do not pose a threat to 128-bit symmetric cryptographic keys like AES-128, contrary to common misconceptions about Grover's algorithm. The article explains why symmetric key sizes do not need to change as part of post-quantum transition efforts, aligning with expert and standardization body consensus.
Anthropic researchers used Claude Mythos Preview to discover improved cryptographic attacks on HAWK (a post-quantum signature scheme) and a weakened version of AES, significantly advancing the state of the art without affecting production systems.
