Why Two Identical PDFs Have Different SHA-256 Hashes (How We Fixed It)
Good explainer on PDF metadata, but this is a known issue with standard library fixes.
Fast, image fingerprinting SDK for Rust.
Yet another image hashing library when imagehash and phash already exist.
Rust developers building image deduplication or similarity search
imagehash · phash · imghash
imgfprint is a Rust library for deterministic image fingerprinting and image similarity detection.
Features: - perceptual hashing - exact hashing - optional CLIP embeddings
Good explainer on PDF metadata, but this is a known issue with standard library fixes.
BLAKE3 speeds file verification 10x over SHA-256; beats SFV/shasum with signatures.
Cargo for Kotlin/Native: no DSL, content-addressed cache, deterministic builds, ships today.
Comprehensive fingerprinting demo, but FingerprintJS already does this in production.
Deterministic JSON hashing solves key-ordering problem, but canonicalization already exists elsewhere.
Structural JSONL fingerprinting that ignores key order using simdjson.
