What is Encrypted with Chatter Encryption?

Chatter Encryption is an application tier encryption that covers data in feed posts and comments, questions and answers, link names, and URLs. It also includes poll choices and questions and content from your custom rich publisher apps.

When you use Chatter encryption when Database Encryption is on, the Chatter encryption happens first using its own tenant secret.

The revision history of encrypted Chatter fields is also encrypted. If you edit or update an encrypted Chatter field, the old information remains encrypted.

Chatter encryption shares the tenant secret used for Fields (Probabilistic) and Files and Attachments.
