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.)
