An external user (Bob) does not have a paid SDS for C&M account. When another user wants to encrypt files for him, SDS for C&M will generate the following keys:
- An external public key (blue key in the diagram). This key is published in the external directory on the SDMC server and can be accessed by all internal and external users. It allows these users to protect files for Bob.
- An external private key (red key in the diagram). It allows Bob to decrypt files that were protected for him. Unlike keys for internal users, the external private key is stored on the SDMC server.
Keys are associated with the user’s e-mail address. They remain the same throughout the use of the SDS for C&M Encryption Portal.
The keystore of an external user, which will be used to decrypt files, contains only the external private key.
