A method for encryption in a distributed datastore is provided. The method generally includes receiving random data from a virtualization management platform as a wrapped data encryption key (DEK), retrieving a key encryption key (KEK) from a key management server (KMS), decrypting the wrapped DEK using the KEK to determine a blank DEK, where the blank DEK is common to a plurality of hosts of a host cluster accessing a distributed datastore; encrypting first data using the blank DEK, and storing the encrypted first data in one or more disks of the distributed datastore, the one or more disks belonging to the plurality of hosts.
