Encryption Management Server Group Keys allow each member of the group to access folders protected by File Share Encryption. The private key is stored on Encryption Management Server and accessed by Encryption Desktop at runtime. The group key is not downloaded to the local keyring of Encryption Desktop.
Group keys cannot be used for email encryption or PGP Zip (file encryption).
To allow multiple users to decrypt email messages or files using a shared key, the only method available is to distribute the private key to all the users who need it. Each user needs to import the private key into their local keyring. This also allows each user to manage their copy of the shared key. For example, they can change the key's passphrase.
If the users only need to encrypt data to the key then it is not necessary to distribute the key because Encryption Desktop can look up the public key on Encryption Management Server.
