Yes, but the magic secret is you ditch the planned offsite event in cahoots with the coworkers you consider your true homies and have an unplanned random adventure at whatever weird destination your employer paid to send you to.

A unified car-area network to provide the shortest path for an attacker to take between the receivers for your wireless tire pressure sensors and virtually cutting your brake or stomping on the gas pedal

Easier for attackers as well. See also control and data plane separation via an isolated management network is hard - let’s go shopping for BlueCoat middleboxes to figure out if we’ve been pwned

curious what you think about my ECDSA + Ed25519 multi-provider Rust signature library which makes extensive use of traits/generics

I saw you made an Unofficial Rust Cryptography WG at . How would you like to help cofound an official one? 😉

Next in our series on eliminating memory safety issues through safe systems programming, we answer the question some of you have asked: why are we talking about ?

Neat. I'd like to prototype something that looks exactly like BIP32 with s/secp256k1/Ristretto255/ though. The main reason is it seems to be what hardware wallet manufacturers want.

If I do implement the full BIP32, it will be a little more interesting than some of the other options for BIP32 in Rust. Namely I'd like the implementation to be generic over a PrimeOrderGroup, and then concretely instantiate it with Ristretto255.

The construction it uses is an extraction/simplification of the symmetric part of Bitcoin's BIP32 ("hardened") derivation. With a bit more work, I'd like to get the `hkd32` crate passing the BIP32 test vectors, and possibly use it to implement the full BIP32.

Weekend project: `hkd32` crate - derive a hierarchy/tree of child symmetric keys from a parent key or 24-word mnemonic phrase, where each child key is described by a derivation path

Remove that much elevation from what Coloradans consider a mountain and it’d still be over 10,000ft
