EncryptedNote is a zero-knowledge service for sharing self-destructing encrypted notes. It addresses the need to transmit sensitive information such as passwords, API keys, or other secrets without creating permanent records that could be accessed later.
Users write a secret message in the browser, generate a one-time link, and share it. The note is encrypted end-to-end using XChaCha20-Poly1305 before transmission, so the service cannot read its content. After the recipient opens the link and reads the message, the note is permanently deleted. No account or signup is required, and the tool works on any device. It provides instant sharing with no permanent records kept.
The service is positioned for private notes, password sharing, and API key sharing. It allows secure one-time transmission of credentials to developers or colleagues without relying on email, chat, or external password managers. Options exist to set auto-destruct behavior at creation time. The interface includes a note history view and explanatory sections on how it works and what it does not protect against.
EncryptedNote is delivered as a web-based tool. It is free forever with no paid tiers mentioned.
