Encryption carried out in your web browser protects the data from the server, the cloud,
and the NSA.
The secret encryption key is stored in the URL < a href = "https://en.wikipedia.org/wiki/Fragment_identifier" > fragment identifier< / a > which is never sent to the server but is available to javascript so by sharing the URL, you give authorization to others who want to participate.< / p >
< p > This project uses the < a href = "http://ckeditor.com/" > CKEditor< / a > Visual Editor
the < a href = "https://github.com/xwiki-contrib/chainpad" > ChainPad< / a > realtime engine.< / p >

< p > CryptPad uses a variant of the
< a href = "https://en.wikipedia.org/wiki/Operational_transformation" > Operational transformation< / a >
algorithm which is able to find distributed consensus using a Nakamoto Blockchain, a construct
popularized by < a href = "https://en.wikipedia.org/wiki/Bitcoin" > Bitcoin< / a > . This way the
algorithm can avoid the need for a central server to resolve Operational Transform Edit
Conflicts and without the need for resolving conflicts, the server can be kept unaware of the
content which is being edited on the pad.< / p >
