Content Signing Service

Content Signing Service (earlier known as PDF Service 2.0) lets you sign documents using DigiCert® Document Trust Manager REST API. It calculates the hash of the document and embeds the signed hash or signature with elements required for establishing the validity of a signature such as Online Certificate Status Protocol (OCSP) response, certificate chain and timestamp.
