new post about E4's cryptography, answering questions such as: - why AES SIV and not GCM? - why SHA-3 and not BLAKE2? - what about side channels? - how are keys stored? etc.

someone claims to have "cracked" RSA, should I tell him that Time AI already did?

yeah but I find witness confusing cos it's also used in the contest of zero-knowledge proof and NP languages for example, something more specific to hash trees may be better imho

authentication path, Merkle path, Merkle proof, inclusion proof.. looks like we need a standard term for this, any other candidates? /cc

before our post on E4's crypto, this writeup by starts by talking of threat modelling, functional constraints, trust assumptions, business needs, platform support, etc. the opposite or typical twitter/HN is-it-secure-or-insecure discussions

doesnt scale to random dishwasher runs every other day, and it's only a 10min job; only AI and blockchain can help here

my maid is doing this once every week so that's fine; dishwasher runs more frequently so that's a problem; we need to make the world a better place with autonomous AI-based dish bots that are better than this: joint venture with and ?

billion-dollar business idea: a product that empties a dishwasher automatically and stacks clean dishes at the right place; I'll be the first customer

We put together a site to look for applied crypto research. Eprint is great, but wading through 1500 papers/yr for 100 practical papers is 💩. Join us and help out!

you don't always have the luxury to choose the best/coolest/fastest primitives when you depend on many other components :)

key takes the whole first block, so yeah it's padded, and message data starts in the second block

I think you're right, so if you hash 2^64-1 bytes with B2s and a key then there would be a counter overflow in the very last block, correct?
