<p>
Identifies the asymmetric KMS key that will be used to verify the signature. This must be the same KMS key that
was used to generate the signature. If you specify a different KMS key, the signature verification fails.
</p>
<p>
To specify a KMS key, use its key ID, key ARN, alias name, or alias ARN. When using an alias name, prefix it with
<code>"alias/"</code>. To specify a KMS key in a different Amazon Web Services account, you must use the key ARN
or alias ARN.
</p>
<p>
For example:
</p>
<ul>
<li>
<p>
Key ID: <code>1234abcd-12ab-34cd-56ef-1234567890ab</code>
</p>
</li>
<li>
<p>
Key ARN: <code>arn:aws:kms:us-east-2:111122223333:key/1234abcd-12ab-34cd-56ef-1234567890ab</code>
</p>
</li>
<li>
<p>
Alias name: <code>alias/ExampleAlias</code>
</p>
</li>
<li>
<p>
Alias ARN: <code>arn:aws:kms:us-east-2:111122223333:alias/ExampleAlias</code>
</p>
</li>
</ul>
<p>
To get the key ID and key ARN for a KMS key, use <a>ListKeys</a> or <a>DescribeKey</a>. To get the alias name and
alias ARN, use <a>ListAliases</a>.
