<p>Get information about a parameter.</p> <p>Request results are returned on a best-effort basis. If you specify <code>MaxResults</code> in the request, the response includes information up to the limit specified. The number of items returned, however, can be between zero and the value of <code>MaxResults</code>. If the service reaches an internal limit while processing the results, it stops the operation and returns the matching values up to that point and a <code>NextToken</code>. You can specify the <code>NextToken</code> in a subsequent call to get the next set of results.</p> <important> <p>If you change the KMS key alias for the KMS key used to encrypt a parameter, then you must also update the key alias the parameter uses to reference KMS. Otherwise, <code>DescribeParameters</code> retrieves whatever the original key alias was referencing.</p> </important>
