Sign(string, string, string, string, Signature)

Sign the document with the given type signature which is placed in already presented signature field. Before signing signature field must be empty, i.e. field must not contain signature dictionary. Thus pdf document already has signature field, you should not supply the place to stamp the signature, corresponding page and rectangle are taken from signature field which is found by signature name (see SigName parameter).

public void Sign(string SigName, string SigReason, string SigContact, string SigLocation, 
    Signature sig)

Parameter	Type	Description
SigName	String	The name of the signature field.
SigReason	String	The reason of signature.
SigContact	String	The contact of signature.
SigLocation	String	The location of signature.
sig	Signature	The type of the signature, could be PKCS1, PKCS7 and PKCS7Detached.

Examples

[C#]
string inFile = TestPath + "example1.pdf";
string outFile = TestPath + "signature.pdf";
PKCS1 sig = new PKCS1("certificate.pfx", "password");
PdfFileSignature pdfSign = new PdfFileSignature(inFile, outFile);
pdfSign.SignatureAppearance = TestPath + "butterfly.jpg";
pdfSign.Sign("Signature1", "Allen", "success", "ChangSha", sig);
pdfSign.Save();

[Visual Basic]
Dim inFile As String = TestPath & "example1.pdf"
Dim outFile As String = TestPath & "signature.pdf"
Dim sig As PKCS1 = new PKCS1("certificate.pfx", "password")
Dim pdfSign = new PdfFileSignature(inFile, outFile)
