C(ryptographical) E(xpendable) Notes

What is this?¶
An effort to support encryption/decryption of expendable notes It consists of multiple projects:
Library : To serve as a library for easier use of encryption/decryption functions
Backend: To serve as a remote endpoint for handling and storing encrypted notes
Frontend: To provide a UI for easier usage
- CLI: To provide a cli interface and give the ability to encrypt a note locally before
sending to the server. This serves as an extra paranoia check in case you don’t trust the server.
An example using the backend and the frontend can be found at https://cenot.es
Features¶
Symmetric encryption of notes using the pynacl project
- On the fly encryption/decryption
Notes can be encrypted/decrypted on the fly without storing anything on the server
- Expiration date notes
After that date, the notes are deleted and cannot be retrieved (default is never)
- Notes that are deleted after N visits
After N retrievals of a note, the note is deleted (default is 1)
- Duress key for immediate note deletion
Using the duress key instead of the real decryption key will delete the note and respond as if the note didn’t exist (to avoid indicating the use of the duress key)
- Persistent visit notes
Notes can be marked as “persistent visit” so that that they are not deleted based on visit count. These are not stored on the server and can be used across different backend servers.
