imagemagick/magickcache

MagickCache is a tool for storing and retrieving large collections of digital media, images, videos, audio, and text metadata, in a single organized local folder. It's designed to handle enormous libraries, scaling up to billions of files, while keeping access fast. It works alongside ImageMagick, a widely used image processing toolkit. At a high level, you create a cache on your local filesystem, protected by a passkey (which can be a simple password or any chunk of data). Then you add content to it using straightforward commands, giving each item a structured path like a filing system, for example, movies/image/mission-impossible/cast/rebecca-ferguson. You can set items to expire automatically after a set time-to-live (say, two days), or let them persist indefinitely. When retrieving images, you can pull just a portion of an image or resize it on the way out, and you can convert between formats (JPEG to PNG, for instance) during extraction. Images can also be scrambled with a passphrase so that even the cache owner can't view the original content without it. The tool is built for teams or organizations managing large digital media libraries, a streaming service storing cast photos and movie metadata, an archive keeping billions of tagged images, or anyone who needs a structured, queryable media repository on their own hardware. Multiple users can share a single cache, but each user can only access their own content unless they're the cache owner, who can see and manage everything. One notable tradeoff: the README is upfront that the security model isn't cryptographically strong. Anyone with direct disk access to the cache folder can potentially read its contents. The passkey system controls access through the tool itself, not through encryption of the underlying data (except for optional image scrambling). The repository is also portable, you can copy the entire cache folder to another machine and keep using it with the same passkey.
