How are hashes computed safely?

All hashes (SHA-1, SHA-256, SHA-512) are calculated using the browser-native `SubtleCrypto` interfaces, which compile binary buffers directly in browser memory. This is highly secure, runs completely offline, and does not upload your files/data to any network nodes.

What is a checksum?

A checksum is a unique string value that acts as a digital fingerprint for a file. If even a single byte of a file changes (e.g. during a network download error), the checksum will change completely. It is standard practice to publish checksums next to software downloads so users can verify the integrity of the downloaded file.
