Inherits DigitalSignatureSaveOptions- Inheritance:
- System.ObjectPdfDigitalSignatureSaveOptions
Remarks
Presentation will be digitally signed when saved to a PDF if Certificate, CertificateBytes or CertificatePath is specified, if PdfDigitalSignatureSaveOptions instance is created with FromSigner(Func<String>, Func<Int32>, Func<Stream, Byte[]>) method or if Sign(Stream) method is overridden, otherwise it will be saved but not digitally signed.
note
If your project doesn't target Windows platform, to use PdfDigitalSignatureSaveOptions, make sure your project references NuGet package System.Security.Cryptography.Pkcs.

Methods
FromSigner(Func<String>, Func<Int32>, Func<Stream, Byte[]>)
Initializes a new instance of the PdfDigitalSignatureSaveOptions class from the specified signer.
public static PdfDigitalSignatureSaveOptions FromSigner(Func<string> signatureFormatFunc, Func<int> estimatedSignatureLengthFunc, Func<Stream, byte[]> computeSignatureFunc)Public Shared Function FromSigner(signatureFormatFunc As Func(Of String), estimatedSignatureLengthFunc As Func(Of Integer), computeSignatureFunc As Func(Of Stream, Byte())) As PdfDigitalSignatureSaveOptionsParameters
signatureFormatFunc- System.Func<System.String>
A delegate that returns the format of the signature content that the signer produces.
estimatedSignatureLengthFunc- System.Func<System.Int32>
A delegate that returns the estimated length of the signature content (in bytes) that should be large enough to contain the entire data returned by the computeSignatureFunc delegate.
computeSignatureFunc- System.Func<System.IO.Stream, System.Byte[]>
A delegate called when saving the PDF file that takes the PDF file stream (without signature's Contents entry) as an input and returns the signature that will be set as the value of the signature's Contents entry.
Returns
A new instance of the PdfDigitalSignatureSaveOptions class from the specified signer.
