Is there any code available online for the chaos-based hash algorithm CHA-1?

I am trying to apply the methodology of this paper to blockchain applications.

  • $\begingroup$ Ok thank you for the helpful feedback @fgrieu , but since i am interested on studying adaptable hashing ,meaning the way the algorithm is prepossessed is changing on different conditions (which the sensitivity on initial conditions chaos provides) , Do you have any suggestions for that? (maybe i will post similar thread) $\endgroup$

  • $\begingroup$ "adaptable hashing, meaning the way the algorithm is prepossessed is changing on different conditions" seems to be what HMAC does. It turns SHA-256 or SHA-512 into hashes parameterized by a key. SHA-3 makes it even simpler (just hash the appropriately padded key before the message). $\endgroup$

This is an obscure and not peer-reviewed article of dubious quality (I'm being polite). It has far too many flaws to list here. It should be best left ignored. The author did not publish a reference implementation, and the software they used is most likely just a proof-of-concept, not usable in practice.

  • $\begingroup$ Thank you for the answer , I am following the methodology from the following literature : researchgate.net/publication/253155858 and I also trying to a proof-of-concept on adaptive hashing on the blockchain. Sorry for not being more descriptive in my initial question. $\endgroup$

    $\begingroup$ As above, that's not a recommended hash function. Don't use it. ALL hash functions involve chaos theory, that's not an interesting feature, more a trivial pre-requisite. $\endgroup$

    $\begingroup$ @econ What you describe as "adaptable/adaptive hashing" does not make sense. Maybe you are looking for keyed hashing algorithms, such as HMAC or SHA-3. $\endgroup$

  • $\begingroup$ @A.Hersean: actually, SHA-3 is not keyed. Might you mean KMAC? $\endgroup$
