There Is No Diffie-Hellman but Elliptic Curve Diffie-Hellman (keymaterial.net)
When I first learned about Diffie-Hellman and especially elliptic curve Diffie-Hellman, I had one rather obvious question: Why elliptic curves? Why use this strange group that seems rather arbitrary, with its third intersection of a line and then reflected? Why not use, say, the Monster Group? Surely a monster is better equipped to guard your secrets than some curve thing named after, but legally distinct from, a completely different curve thing!

WireGuard vanity keygen (github.com/axllent)
A command-line vanity (public) key generator for WireGuard. By default, it only matches the prefix of generated public keys, and not whether the search matches anywhere in the public key. The concept is based on wireguard-vanity-address, however I wanted something a little more streamlined.

The cryptography behind passkeys (trailofbits.com)
When most people think of cryptography, the first thing they typically think of is encryption: keeping information confidential. But just as important (if not more) is authenticity: ensuring that information is really coming from an authentic source.

The Linux Kernel's PGP Web of Trust (kleine-koenig.org)
The Linux kernel's development process makes use of PGP. The most relevant part here is that subsystem maintainers are supposed to use signed tags in their pull requests to Linus Torvalds. As the concept of keyservers is considered broken, Konstantin Ryabitsev maintains a collection of relevant keys in a git repository.

TIL Alice and Bob were almost Adolf and Bertholdt. Rich Schroepell responds to Ron Rivest and the RSA paper in 1977 and suggests naming the protagonists Adolf and Bertholdt. Rivest, Shamir and Adleman eventually used Alice and Bob, but the suggestion came from Schroepell originally.

What the heck is AEAD again? (ochagavia.nl)
Here’s a problem you might be familiar with: I keep forgetting what AEAD exactly means and why you would ever use it. Yes, I know the acronym stands for “Authenticated Encryption with Associated Data”, but does that really clarify anything? Not to me, so I’ve finally decided to sit down and write this blog post as a piece of help for my future self… and for anyone else who finds AEAD hard to retain.

Offical XRP NPM package has been compromised and key stealing malware introduced (aikido.dev)
At 21 Apr, 20:53 GMT+0, our system, Aikido Intel started to alert us to five new package version of the xrpl package. It is the official SDK for the XRP Ledger, with more than 140.000 weekly downloads. We quickly confirmed the official XPRL (Ripple) NPM package was compromised by sophisticated attackers who put in a backdoor to steal cryptocurrency private keys and gain access to cryptocurrency wallets.

Syncing Keyhive (inkandswitch.com)
The last few lab notes have focused on the cryptographic components which support a local first access control system. Those being a capability based system for managing write access to documents, and a key agreement protocol for encrypting and decrypting writes (thus implementing read control). We now have to think about how to actually transfer this data between devices.
