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.
