Show HN: I wrote a program that hashes files into poems

A developer created a program called Rhymesum that generates five-line poems as file fingerprints by computing a BLAKE3 hash and using it to seed an LLM sampler. The toy project, which is not cryptographically secure, outputs poems instead of traditional checksums to represent file identity.

Note: This is a toy project and far from cryptographically safe, better don't use it in production. This project lets you fingerprint your files using LLM-generated poems instead of hard-to-remember checksums. It computes a BLAKE3 hash of the passed file, and based on that injects entropy in both the LLM sampler as well as the prompt itself. The output is a five-line poem representing a fingerprint of your file.
