Tornote

Self-destructing notes written on Go with Stanford JS Crypto Library for client-side encryption/decryption.

Latest stable version deployed on https://tornote.herokuapp.com/

Security aspects

AES-256 encryption used with 27 bytes secret key (randomly generated on client).
All private data including secret not leaving a web-browser without encryption.
Server stored only anonymous encrypted data (without any reference to author or reader).
Note decrypted on the client-side via the SJCL and immediately deleted on server after reading.

If you have ideas to improve the our safety/security so far as possible please post the issue.

Configuration settings can be set with .env file or environment.

DATABASE_URL - Data source name (DSN) for PostgreSQL database.

SECRET_KEY - Server secret used for CSRF protection.
