What the security tools do
Half of this category exists because so much text now ends up in AI chats. The API Key & Secret Scanner looks through code, logs or a prompt for the secrets people paste by accident: AWS, GitHub, OpenAI, Anthropic and Stripe keys, Slack and Discord webhooks, private keys, JWTs and database URLs with a password in them. It shows each match and gives you a redacted copy.
The PII Redactor does the same job for personal details. It swaps names, emails, phone numbers, addresses and card numbers for placeholders before you paste a document into ChatGPT, then puts the real details back into the reply.
The older two are classics. The Password Generator uses your browser’s cryptographic random number generator with the length and character sets you pick; if in doubt, go longer rather than adding symbols. The Hash Generator turns any text you paste into an MD5, SHA-1, SHA-256 or SHA-512 digest. Use SHA-256 or SHA-512 for anything security related. MD5 and SHA-1 are only fine for legacy checksums.
All four run in your browser, which is the point for a tool you paste secrets into. Not sure what’s risky? Start with what not to paste into ChatGPT.
