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 v1.7.8 release.
