Specifies whether the volume should be encrypted. Encrypted Amazon EBS volumes may only be attached to instances that support Amazon EBS encryption. Volumes that are created from encrypted snapshots are automatically encrypted. There is no way to create an encrypted volume from an unencrypted snapshot or vice versa. If your AMI uses encrypted volumes, you can only launch it on supported instance types. For more information, see Amazon EBS Encryption (http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/EBSEncryption.html) in the Amazon Elastic Compute Cloud User Guide.
