Interesting hash!

I have a question about the licensing:

If I implement the algorithm from the specification, is my implementation obliged to use the 1BSD license? It is impossible to implement the algorithm without also reading the reference implemmentation.

Sorry about the lack of key details in the spec; I will improve it to avoid referring to the reference implementation.

A reimplementation isn't obliged to use the license; it is your original expression and copyright.

Any similarities are coincidental due to the convergence of expression caused by implementing the same, very specific procedure.

Thank you so much.

So here's a Python implementation: https://codeberg.org/kas/jphash

The specification now details the eight cases for combining the pieces into the output string.

That looks really great!

There is now a Firefox add-on in the firefox/ subdirectory.

This provides a toolbar button which will replace the content of the current input field with the JP-Hash of its current contents.

The keyboard shortcut for that action is Alt-J.

PS: It's not a problem per se that one has to look up the words in the reference implementation(s). It must be a PITA to write a specification that enables anyone to write an independent implementation. It would only be a problem if using the MORA from the reference implementation obliged every implementation to use the 1BSD license.
