It was over 20 years ago now, and I don't remember which library it was, but I ran across a type-1 UUID library that stored the timestamp of the latest UUID it handed out in a static (or maybe thread-local, I forget) variable, and woul

If you want privacy and anonymity, be careful about how you're generating your UUID. Some flavors of UUID are just the MAC address, process ID, and timestamp, which makes them trivially guessable (and poorly scalable). Instead of a UU

Well, I doubt the Winter War is covered much in Russian secondary school. "You're going to Finland" probably doesn't cause Simo Hayha[0] to visit Russian soldiers in their nightmares. [0] https://ifunny.co&#x

Thanks. I know a guy who was trained to place demolition charges on the US warheads in Buchel in case the base was overrun, and I had gotten the false impression from him that all of the warheads had since been removed.

Germany has never had nuclear weapons of its own, though the US has had around 60 warheads in Buchel (edit: and currently probably has about about 20 warheads) as part of the NATO Nuclear Sharing deterrent, and the Soviet Union deployed som

Ahh... I've misunderstood that extra bit, and I think it's never at the 2**128 position. I've misread the code for padding. A stop bit is used to disambiguate zero padding from messages that end in zeroes, similar to most h

Point taken about different partitions of the IV into counter and nonce. As far as GCM GHASH vs Poly1305, they use the same math. Just one is in a Galois field modulo the prime 2**130 - 5 and the other is in a 128-bit binary Galois field re

Is there a well-reviewed paranoid alternative to libnacl/libsodium, given that ChaCha20-Poly1305 is just as brittle to nonce reuse as AES-GCM? I trust libsodium/libnacl's randombytes_buf to give me unique nonces as long as I

No new systems need to be developed, only a will to deploy existing systems. To the best of public knowledge, Curve25519 with AES-GCM or ChaCha20-Poly1305 is good enough to keep the NSA out for years. These are available in TLS, OpenVPN,
