Cryptgeon is a secure, open source sharing note or file service inspired by PrivNote, written in rust and svelte. Each document note has a 512bit generated id that is used to retrieve the note. All the data you create through cryptgeon is stored in memory (RAM) and never persists/stays on your disk on the NAS. In this step by step guide I will show you how to install Cryptgeon on your Synology NAS using Docker & Portainer.
Install Docker via Synology “Package Center”.
Install Portainer using my step by step guide. If you already have Portainer installed on your Synology NAS, skip this STEP.
Log into Portainer using your username and password. On the Portainer left sidebar click on Stacks then + Add stack. Follow the instructions in the image below.
In the Name field type in cryptgeon. Follow the instructions in the image below.
version: '3.7' services: memcached: image: memcached entrypoint: memcached -m 128M -I 4M app: image: cupcakearmy/cryptgeon depends_on: - memcached environment: SIZE_LIMIT: 4M ports: - 8120:5000
Note: Limit to 128 MB RAM, 4M per entry, customize with your preference.
Scroll down on the page until you see a button named Deploy the stack. Click on it. Follow the instructions in the image below. The installation process can take up to a few minutes. It will depend on your Internet speed connection.
If everything goes right, you will see this message at the top right of your screen: “Stack successfully deployed“.
Follow my step by step guide to add a Wildcard Certificate with reverse Proxy.
Go back to STEP 1 or you will deal with karma 🙂
Connect to your own Wildcard address, then add a note. You can choose your own retention policy and the note will expire and be destroyed after the set time or views. Click Create. Follow the instructions in the image below.
After you click Create on STEP 10, you can copy and share the note with whomever you want. Follow the instructions in the image below.
The person accessing the link you provided will have to click on show note to see it. Follow the instructions in the images below.
They can also copy the note to their clipboard.
If someone attempts to access the link and you set up a retention policy on STEP 10, they will get a warning message saying that “note was not found or was already deleted”.
Instead of a note, you also have the option to drag and drop a file from your own computer, with the retention policy of your choice. Follow the instructions in the image below.
After you provide someone with the link, they can download the file/files. Follow the instructions in the image below.
