# Know more

## Zero Knowledge

Every tool provided by Cryptpad are based on a Zero Knowledge technology. It means that our server stored only encrypted data, and we have no way to decrypt it. Even data about your account, including your username, are encrypted.

## Realtime

Our tools also use a Realtime technology, which means that you can edit the documents, slides or polls collaboratively with other people. Our unique technology has the advantage of combining both realtime and zero-knowledge at the same time.

## Share documents

When you want to edit a document with other users or invite them to answer to a poll, you just have to share the URL of that document with them. All the information needed to access and edit it are contained in the "hash" of the URL.

## User Account

In order to have Zero Knowledge user accounts, we needed a way to store your settings without knowing your username and password. To do so, our tools generate a unique key from your username and password, directly in your browser.
