I would like to add digial signature on the pdf attachement send in email to secure the document from forgery. Is this possible when we use email template with type visualforce?
<messaging:emailTemplate subject="Quote Created" recipientType="Contact" relatedToType="Quote" >
<messaging:htmlEmailBody >
<c:QuoteEmailBody recordID="{!relatedTo.Id}"/>
</messaging:htmlEmailBody>
<messaging:attachment renderAs="pdf" filename="QuotationSlip">
<c:QuoteSlipDocAttachment recordID="{!relatedTo.Id}"/>
</messaging:attachment>
</messaging:emailTemplate>
QuoteSlipDocAttachment is visualfoce component which will be rendered as pdf when the workflow trigger. Is there anyway i can protect the document using digital signature?
