public void setDataEncryptionKeyId(String dataEncryptionKeyId) {

<p>
The data encryption key identifier for the snapshot. This value is a unique identifier that corresponds to the
data encryption key that was used to encrypt the original volume or snapshot copy. Because data encryption keys
are inherited by volumes created from snapshots, and vice versa, if snapshots share the same data encryption key
identifier, then they belong to the same volume/snapshot lineage. This parameter is only returned by
<a>DescribeSnapshots</a>.
