Abstract

Media, method, and system for providing encryption key management for international data residency. Organizations using a group-based communication system can designate a particular geopolitical area where that organization's data can be stored and another geopolitical area (which may be the same or different) where encryption keys used to encrypt and decrypt that data should be stored. Users of that organization can post message or access messages previously posted on the group-based communication system from any geopolitical area, causing the system to automatically store and retrieve messages and encryption keys from the appropriate regions to allow the users to transparently access the group-based communication system while maintaining security and data residency requirements.
