CryptPad: Open-Source Zero-Knowledge Real-Time Editor

Collaborative editing software with end-to-end encryption for secure online collaboration, keeping data private and protected from unauthorized access.

What is CryptoPad?

CryptPad is an open-source, zero-knowledge, collaborative real-time editor developed by XWiki SAS. It allows multiple people to edit a document simultaneously while maintaining privacy through end-to-end encryption.

When using CryptPad, all data is encrypted before being sent to CryptPad's servers. This means that neither CryptPad nor any attackers are able to access the plaintext content of your documents. Instead, they only see encrypted gibberish. The encryption keys are only stored in your browser, allowing only you and your designated collaborators to access the content.

Some key features of CryptPad include:

• Real-time collaborative editing of rich text documents, spreadsheets, presentations, polls, kanban boards, and source code
• Version history so you can revert changes
• User access controls for public, private, and encrypted pads
• Authenticated access using passwords
• Chat integrated directly into pads for easy collaboration
• Data stored encrypted on CryptPad's servers
• Open source code that can be self-hosted for additional privacy

If you need to collaborate on documents, while prioritizing privacy, CryptPad is an excellent encrypted alternative to services like Google Docs or Office 365. Its zero-knowledge encryption model means your data stays private while being able to work together with others.
