Good to know

  • Processing happens in your browser. Inputs are not saved or sent to a tool endpoint.
  • Use HTTPS or localhost for browser cryptography. These helpers are not a security audit.
  • Basic Auth and JWT payloads are encodings, not encryption. Keep credentials out of shared screenshots.

Your original input stays available until you clear it or leave the page. Privacy details.
