Calculated hashes
Hash calculations are performed locally in your browser. The original file is never uploaded. Hashes are computed using hash-wasm, a widely used open-source hashing library for browsers and Node.js built on hand-tuned WebAssembly binaries. The source code is publicly verifiable on
the official Github repository
