Specifies whether the volume should be encrypted. Encrypted EBS volumes can only be attached to instances that
support Amazon EBS encryption. For more information, see <a
href="https://docs.aws.amazon.com/ebs/latest/userguide/ebs-encryption-requirements.html">Requirements for Amazon
EBS encryption</a> in the <i>Amazon EBS User Guide</i>. If your AMI uses encrypted volumes, you can also only
launch it on supported instance types.
</p>
<note>
<p>
If you are creating a volume from a snapshot, you cannot create an unencrypted volume from an encrypted snapshot.
Also, you cannot specify a KMS key ID when using a launch configuration.
</p>
<p>
If you enable encryption by default, the EBS volumes that you create are always encrypted, either using the
Amazon Web Services managed KMS key or a customer-managed KMS key, regardless of whether the snapshot was
encrypted.
