  • Ciphey

    ⚡ Automatically decrypt encryptions without knowing the key or cipher, decode encodings, and crack hashes ⚡

    • Project mention: CyberChef from GCHQ: The Cyber Swiss Army Knife | news.ycombinator.com | 2024-02-01

    I also discovered Ciphey. Neat little tool indeed, but it's being deprecated. It's mentioned in this issue[1] and being replaced with Ares[2]. Neither could decipher this strange encryption[3] I used it on :(

    • Project mention: Macaroons Escalated Quickly | news.ycombinator.com | 2024-01-31

    I like the "solve the now" perspective here, and having code examples is very helpful to understand some of the rational behind the approach. Having read your previous "tedious survey"[0] post on various token formats, I generally agree with a lot of your conclusions. Curious though about your thought process wrt macaroons vs biscuits.

    To me the one major downside of macaroons has always been the single shared root symmetric key. Many use cases are addressed by third party attenuation, but then there are the problems like key rotation, having to do online verification, no built in encryption, no peer-to-peer support through an "untrusted" fly.io, and no third party token verification without decryption like in signcryption[1] schemes. Of course this is traded off by having to do PK issuance and management so I can see the simplicity of it.

    Is fly.io scoping this pretty hard to just auth tokens with third party attenuation, or do you see further development and maybe moving to other token systems like biscuit when/if the need arises to address those known issues?

    fwiw I've done a bit of research work myself on a token format using signcryption [2] where I explored addressing some of these ideas (but not the attenuation side of it yet, which I get is a big deal here).
