DailyTxT

DailyTxT is an encrypted Diary/Journal WebApp with several features. It is written in Svelte and Go and meant to be run by Docker - supports AMD64 and ARM64.

Features

• Encryption: Everything you write is encrypted before it's written to the server's storage. Even the admin can't read your private stuff!
• File-Upload: You can upload arbitrary files for each day (500 MB max each). They are stored encrypted on the server as well. Images are automatically recognized and added to the...
• Image Viewer: View all images of a day in a gallery view and in full screen.
• Markdown: You can write your entries in markdown and see a live preview.
• Tags: You can add tags to your entries for better organization.
• Search: You can search for any word, tag or filename in your entries.
• Custom Templates: You can create and use custom templates for your entries.
• Read Mode: A distraction-free mode for reading your entries of each month.
• Multi-Language: DailyTxT is currently available in German and English. New languages can be added easily, see TRANSLATION.md for instructions.
• Export to HTML: You can export your entries (including uploaded files) to HTML format.
• Mobile: Responsive design for easy use on mobile screen. Additionally: allows installation as a PWA (Progressive Web App) to your Homescreen.
• Multi-User: You can create multiple User Accounts. Each account uses its own encryption key.
• Admin Panel: You can (among other things) manage users and open registration for 5 minutes.

• A yellow dot in the calendar means, that there are uploaded files for this day.

About encryption and data storage

🔒 For encryption ChaCha20-Poly1305 is used.

When a user logs in, a key is derived from his password with Argon2id, it is called the derived key. The derived key is stored in a http-only cookie and send on every API-call. This key is used to decrypt the user's encryption key (which is randomly generated when the user is created). The encryption key is used to encrypt/decrypt all data of this user (entries and uploaded files) and never leaves the server.

When a user changes his password, the encryption key is decrypted with the old derived key and re-encrypted with a new derived key (derived from the new password).

There is no E2E-encryption used on client-side, because the search-functionality would not work then. All data would have to be sent to client-side for searching.

There are also backup-keys available which can be used as a password-replacement. When they are created, they store the derived key encrypted with a random backup key. These backup keys are shown to the user only once and are to be stored safely by him. When a user loses his password, he can use this backup key to decrypt the derived key and from that the encryption key.

All data is stored in json-files. No database is used, because the main goal is to guarantee highest portability and longterm availability of the data.
