Security best practices when using Hash Generator
What to think about before publishing a identifier generated by Hash Generator on the open internet.
Generating a identifier sounds like it should require an app — and historically it did. Hash Generator runs the same thing in your browser tab, with one tap and no signup.
Open the tool: Hash Generator — Browser-only. Nothing is sent to a server.
Security considerations
Generating a identifier that ends up on the public internet means anyone can read it. That's fine for non-sensitive content. It's not fine for anything you don't want exposed. Hash Generator doesn't make this distinction for you — but you should make it before you generate.
Safe defaults
- Never embed credentials, API keys, or personal IDs in a identifier you publish publicly
- Be wary of identifiers on printed material — they can be photographed, copied, and reused
- For sensitive use cases, generate a identifier that expires (or maps to a server-side resource you can revoke)
Run it in your browser
Everything happens locally in your browser — your file never leaves your device.
