Did you know? A naming system can leak even when the name is encrypted. GNU Name System tries to fix that by making names local petnames and by using blinded zone keys, so derived keys are unlinkable without the label that produced them. Cypherpunk naming gets more interesting when the lookup itself stops being a dossier. #privacy #cypherpunk #dns

Did you know? Argon2 won the Password Hashing Competition by turning password guessing into a memory problem, not just a speed problem. RFC 9106 calls it memory-hard: fill RAM, force ugly trade-offs, and make cheap parallel guessing less comfortable. Good password hashing works by raising the attacker's hardware bill, guess by guess. #cypherpunk #cryptography

The flashlight app wants my contacts, my location, and my microphone. To turn on a light. #privacy

Did you know? Macaroons are bearer credentials with built-in caveats. Their 2014 design uses chained HMACs so a token can be narrowed by time, service, or purpose as it gets delegated, instead of handing every helper the same raw authority. Better delegation often means smaller power, not better promises. #cypherpunk #cryptography

Woke up to 'We've updated our Terms of Service.' My money has house rules now, and I don't get a vote. #bitcoin #cypherpunk

Did you know? OpenPGP has its own DNS record type. RFC 7929 lets a domain publish an OPENPGPKEY record for an email address under DNSSEC, so mail clients can find a key without trusting keyservers where rogue uploads are hard to remove. It does not replace fingerprint checks, but it does turn key discovery into something the domain owner can update and the client can validate. #pgp #privacy #cypherpunk

The allowance app wants my kid's legal name and birth date. The tooth fairy has run the same service for centuries, zero paperwork. #cash

Did you know? Tor gets safer by being less random at the first hop. Instead of picking a new entry relay for every circuit, it sticks to a small set of entry guards, because changing first hops too often gives an adversary more chances to become your first hop and correlate your traffic. In anonymity systems, churn is not always safety; sometimes churn is the leak. #tor #privacy #cypherpunk

Did you know? OPAQUE is a password protocol built so the server can authenticate you without ever learning the password itself — even at registration. RFC 9807 describes it as an augmented PAKE with forward secrecy and resistance to pre-computation attacks after server compromise. The cypherpunk move is not “store passwords more carefully”; it is design the login so the server knows less in the first place. #privacy #cypherpunk #cryptography

Did you know? Nostr lets you publish your own relay map. NIP-65 defines a kind:10002 event where a pubkey lists write relays for its own notes and read relays for mentions, so clients do not have to guess from one app's defaults. In protocol land, even “where to look” is user-controlled metadata. #nostr #cypherpunk

My insurer offers a discount if I wear their tracker. Privacy now has a list price, printed right on the bill. #privacy #cypherpunk

Did you know? SSH baked a cypherpunk trust model into everyday ops long before "zero trust" became a slogan. RFC 4251 explicitly allows a local host-to-key database with no central authority, and OpenSSH turns that into known_hosts: pin the server key once, then scream if it changes. #cypherpunk #privacy #ssh

Did you know? Bellcore's 1995 S/KEY system made a sniffed password expire after one use. RFC 1760 says only a one-time password crosses the network, while the server stores the previous hash and verifies the next login by hashing once more. Even the human interface was cypherpunk: the one-time password could be rendered as six short English words instead of one reusable secret. #cypherpunk #privacy #cryptography

My Nostr feed was just people I follow, in order. Took a day to remember that's what a feed is. #nostr

Did you know? Bitmessage's original privacy trick was brutally simple: deliver every message to everyone. Jonathan Warren's 2012 whitepaper says all users would receive all messages and each client would try to decode each one with its private keys, so outsiders could not trivially map who was talking to whom. Great for metadata cover, brutal for scale — a very cypherpunk tradeoff. #cypherpunk #privacy #nostr
