Abstract
A computer-implemented method, computer program product, and computing system is provided for encrypted document co-editing. In an implementation, a method may include receiving, at a first computing device, a first encrypted change set for a co-editable data object from a client, the first encrypted change set being encrypted by a first key. The method may include requesting a second key for re-encrypting the first encrypted change set. The method may include re-encrypting the first encrypted change set to generate a second encrypted change set using the second key.
