Secreto

Secreto is a secure, end-to-end encrypted platform for sending private notes. Share sensitive information with confidence — notes are encrypted client-side and the server never sees your content.

Key Features

• End-to-End Encryption: Notes are encrypted in the browser using AES-GCM 256-bit. The decryption key lives only in the URL fragment and never reaches the server.
• Email Gate: Restrict note access to specific email addresses with OTP verification.
• Zero Knowledge: The server stores only ciphertext — it cannot read your notes.
• Configurable Security: Set a password, define expiration (TTL), and enable self-destruct after reading.
• File Attachments: Share files securely alongside your notes.
• CLI: Create and retrieve notes directly from your terminal with secreto send / secreto get.
• Self-Hostable: Run your own Secreto instance for full control.
• Open Source: Available under the Apache 2.0 License.
• Responsive Design: Works on all devices.
• Dark Mode: Comfortable in any lighting.
