Secnote is a simple web app for sending confidential messages that self-destruct after being read. Each note is encrypted end-to-end using XSalsa20-Poly1305 and accessible via a single-use link. No sign-up required.
Useful for sharing sensitive information like credentials or one-time messages without leaving a trace.
Very cool program especially for secrets.
You can add the ability to attach files to notes, but this is a difficult task, especially if they are photos.
