  • I just wanted to compare FOSS Linux budgeting software

    Jump

  • There's also text-based tools - not sure if they fit your needs. beancount (with 'fava' has a nice web UI), ledger, hledger. Good thing about text based is: you can easily use git.

    Not sure if they go as 'budgeting' software. 'Accounting' might be more accurate.

  • Request for comments on a encrypted messaging protocol I'm developing

    Jump

  • Honestly I'm not sure what the definition says. But in case of the original axolotl/signal protocol the 'ratchet' construction in my understanding allows to recover from a key compromise given that the attacker is passive (read only). Let's say you have to hand your phone to the police, they disappear with it for a moment and get a copy of all the keys you use for the axolotl protocol. As long as they don't manage to manipulate network traffic but only intercept everything your chat session will 'recover' once a new (EC)DH agreement is completed with your chat partner. This might not happen immediately though in case your chat partner is offline.

    This property (securing future messages) can only be achieved with asymmetric cryptography. Securing past messages can in principle be achieved with symmetric cryptography: You could imagine a ratchet mechanism where each chat partner computes a new key by transforming the old key with a entropy-preserving and hard-to-invert function (such as sha3) and then deleting the old key (and also best deleting old messages).

    P.S. Just did some reading: https://signal.org/docs/specifications/doubleratchet/

     
        
Forward security: Output keys from the past appear random to an adversary who learns the KDF key at some point in time.

Break-in recovery: Future output keys appear random to an adversary who learns the KDF key at some point in time, provided that future inputs have added sufficient entropy.

    So what I meant is not called forward secrecy but break-in recovery. Confusing terms.

  • US, a risk for open source repos?

    Jump

  • In m opinion this is a real risk. In case od Organic maps already started happening. The FOSS community should move away from github and consider alternatives like codeberg.org (germany) or self-hosted forgejo instances to mitigate the risk.

  • Generally seems an okay idea to me because it allows you to use the rust tool-chain and you can more easily achieve compatibility with other rust code. In fact, there's other languages which do something similar. I remember F* (f-star) which compiles to OCaml.

  • The basics of the Fediverse. Facebook, Twitter, Tiktok, Reddit, ... vs the Fediverse. What do you think?

    Jump

  • In thie fesiverse graphic each person has exactly 1 connection to a fediverse thing. But in reality, there can be more. I guess in practice there are often more than one.
