The following C# code example digitally signs 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 performed. Because no CRL or OCSP server information
is specified, the server information is obtained from the certificate used
to digitally sign the PDF document. The signed document is saved
as a PDF file named LoanSigned.pdf. (See Digitally Signing PDF Documents.)
