Quick Start (MTOM): Certifying a PDF document using the web service API

The following C# web service code example certifies a PDF document that is based on a PDF file named LoanSig.pdf. The alias that is specified for the security credential is secure, and revocation checking is not performed. The certified document is saved as a PDF file named LoanCertified.pdf. (See Certifying PDF Documents.)
