This Secret Note Editor is a professional, in-browser tool designed for creating, editing, and securing your private notes, seamlessly supporting both text and pasted images. It ensures the utmost confidentiality by performing all encryption and decryption directly within your web browser. Images are automatically converted to Base64 data URLs upon paste, integrating them directly into the note content, which is then fully encrypted alongside your text, employing robust cryptographic standards such as AES-GCM for symmetric encryption and PBKDF2 with a high iteration count for secure key derivation. This client-side approach guarantees that your sensitive information, including embedded images, is never transmitted to or stored on any server, giving you complete control over your data's privacy and security.
