Show HN: Ciid – Chronological Image Identifier, Written in Rust

I have an image library of around ~15,000 RAW photo images, which I wanted to organize. After having tried several approaches over the years (organizing them in folders by topic, by year, or some mix of the two...) I gave up and went to build a solution that scales better.

ciid is a CLI utility, which you can use to rename image files, so that you can fearlessly merge folders without having to worry about duplicate file names.

The derived identifiers are structured in such a way that if you sort them alphabetically, the images will also be sorted chronologically. Additionally, the identifier can later be used to verify the integrity of the image.

If you have any questions, I'd be happy to answer.
