@gltch.ioRSA is weaker than we thought! New forgery attack cuts 1024-bit key security to 65 bits—a massive drop from the required 128+. Even 2048/4096 bit keys weakened. #cryptography

@light.noc.social.ap.brid.gyI propose that the amount of information entropy encoded in one word in the @eff large wordlist shall be called "1 eff", equal to approx. 12.9 bits. Thus, a standard diceware passphrase using that wordlist contains about 6 or 7 effs of entropy.
@informaq.bsky.socialApple commits to Merkle Tree Certificates for TLS with three cosignatures and stricter requirements than Chrome, while adopting composite ML-DSA algorithms for S/MIME email security, advancing industry post-quantum PKI transition toward 2027-2028.

@pulseofnations.lolStarkWare says a week of AI-assisted optimization cut the estimated cost of a quantum-resistant Bitcoin transaction from $320 to $66, though big limits remain.

@informaq.bsky.socialETSI's new framework reveals QRNGs require comprehensive validation across all pipeline stages, not just quantum sources. Side-channel vulnerabilities can undermine cryptographic randomness despite statistical soundness.
