We use the browser's native `crypto.getRandomValues()` API to ensure the generated passwords have high entropy and are unpredictable, unlike standard random number generators.
No, SHA-256 is a cryptographic hash function that is designed to be a one-way operation. You can generate a hash from text, but you cannot mathematically derive the original text from the hash.
