PrivateBin is a minimalist open source web service that allows you to create a paste of your text output and bind it to a single URL that you can then share. It’s similar to Yopass and Password Pusher. This method is perfect for sharing private information inside a Facebook chat, WhatsApp chat or any other IM platform, email etc. The end-user would just click on the link and get the output in a browser. The information will be automatically deleted/destroyed at a time of your choice: as soon as the receiver reads it, after a few minutes, after a week or several months etc. Data is encrypted and decrypted in the browser using 256bit AES in Galois Counter mode. In this step by step guide I will show you how to install PrivateBin on your Synology NAS using Docker.

💡Note: This guide works perfectly with the latest PrivateBin v2.0.0 release.

🟢Please Support My work by Making a Donation. Almost 99,9% of the people that install something using my guides forget to support my work, or just ignore STEP 1. I’ve been very honest about this aspect of my work since the beginning: I don’t run any ADS, I don’t require subscriptions, paid or otherwise, I don’t collect IPs, emails, and I don’t have any referral links from Amazon or other merchants. I also don’t have any POP-UPs or COOKIES. I have repeatedly been told over the years how much I have contributed to the community. It’s something I love doing and have been honest about my passion since the beginning. But I also Need The Community to Support me Back to be able to continue doing this work.

• STEP 18

Now open your browser and type in your HTTPS/SSL certificate like this https://privatebin.yourname.synology.me In my case it’s https://privatebin.mariushosting.synology.me If everything goes right you will see the Privatebin dashboard page. Add your text, select the expiration time, burn after reading, optionally set up a password then click Create. At the top right of the page you also have the option to switch the theme to dark mode. Follow the instructions in the image below.
