/**
 * You can secure a PDF document by certifying it with a particular type of signature called a certified signature.
 * A certified signature is distinguished from a digital signature in these ways:
 *
 * It must be the first signature applied to the PDF document; that is, at the time the certified signature is applied, any other signature fields in the document must be unsigned.
 * Only one certified signature is permitted in a PDF document. If you want to sign and certify a PDF document, you must certify it before signing it.
 * After you certify a PDF document, you can digitally sign additional signature fields.
 *
 * The author or originator of the document can specify that the document can be modified in certain ways without invalidating the certified signature. For example,
 * the document may permit filling in forms or commenting. If the author specifies that a certain modification is not permitted, Acrobat restricts users from modifying the document
 * in that way. If such modifications are made, such as by using another application, the certified signature is invalid and Acrobat issues a warning when a user opens the document.
 * (With non-certified signatures, modifications are not prevented, and normal editing operations do not invalidate the original signature.)
 *
 * At the time of signing, the document is scanned for specific types of content that could make the contents of a document ambiguous or misleading. For example, an annotation could
 * obscure some text on a page that is important for understanding what is being certified. An explanation (legal attestation) can be provided about such content.
 * You can programmatically certify PDF documents by using the Signature service Java API or the Signature web service API. When certifying a PDF document, you must reference a security
 * credential that exists in the Credential service.
 *
 * Note: When certifying and signing the same PDF document, if the certify signature is not trusted, a yellow triangle appears next to the first sign signature when you open the PDF document in Acrobat or Adobe Reader.
 * The certifying signature must be trusted to avoid this situation.
 *
 * The following Java code example certifies a PDF document that is based on a PDF file.
 *
 * PreRequisites - Digital certificate for certifying the document has to be uploaded on AEM Key Store.
