About Secret Note Sharer
The Secret Note Sharer provides a secure way to share sensitive information like passwords, API keys, private messages, or code snippets. Your content is encrypted using industry-standard AES-256-GCM encryption directly in your browser before being stored on our servers.
What makes this tool unique is its zero-knowledge architecture. The encryption key is stored in the URL fragment (the part after #), which browsers never send to servers. This means we cannot read your notes even if we wanted to. When you add password protection, the key is derived from your password using PBKDF2 with 100,000 iterations.
Self-destructing notes add an extra layer of security. When you set a read limit, each time someone views the note counts as one read. Once the limit is reached, the encrypted data is permanently deleted from our servers. Combined with time-based expiration, you can ensure sensitive information doesn't persist longer than necessary.
For sharing code snippets, select the appropriate programming language to enable syntax highlighting on the view page. This makes it easy to share and read code securely.
