https://arxiv.org/ https://arxiv.org/ As suggested here, perhaps consider writing up and submitting a short article to arxiv. That ought to be enough to ensure credit. If you don't intend to patent it (don't know where you are located & local laws), the arxiv preprint service will give you a citable, dated & externally validated submission that you can use. It wouldn't be peer reviewed until you submit it to an appropriate journal, but that's a relatively short step away once you upload the preprint to arxiv.
