Member Function Documentation

◆ GetByteRange()

virtual PdfArray iText.Signatures.PdfSignature.GetByteRange ( )

inlinevirtual

Gets the /ByteRange.

Returns: an array of pairs of integers that specifies the byte range used in the digest calculation. A pair consists of the starting byte offset and the length.

◆ GetCert()

virtual PdfString iText.Signatures.PdfSignature.GetCert ( )

inlinevirtual

Gets the /Cert entry value of this signature.

Gets the /Cert entry value of this signature. See ISO 32000-1 12.8.1, Table 252 – Entries in a signature dictionary.

Returns: the signature cert

◆ GetCertObject()

virtual PdfObject iText.Signatures.PdfSignature.GetCertObject ( )

inlinevirtual

Gets the /Cert entry value of this signature.

Gets the /Cert entry value of this signature. /Cert entry required when SubFilter is adbe.x509.rsa_sha1. May be array or byte string.

Returns: the signature cert value

◆ GetContents()

virtual PdfString iText.Signatures.PdfSignature.GetContents ( )

inlinevirtual

Gets the /Contents entry value.

Gets the /Contents entry value. See ISO 32000-1 12.8.1, Table 252 – Entries in a signature dictionary.

Returns: the signature content

◆ GetDate()

virtual PdfString iText.Signatures.PdfSignature.GetDate ( )

inlinevirtual

Gets the /M value.

Gets the /M value. Should only be used if the time of signing is not available in the signature.

Returns

iText.Kernel.Pdf.PdfString which denotes time of signing.

◆ GetLocation()

virtual String iText.Signatures.PdfSignature.GetLocation ( )

inlinevirtual

Gets the /Location entry value.

Returns: physical location of signing.

◆ GetName()

virtual String iText.Signatures.PdfSignature.GetName ( )

inlinevirtual

gets the /Name of the person signing the document.

Returns: name of the person signing the document.

◆ GetSubFilter()

virtual PdfName iText.Signatures.PdfSignature.GetSubFilter ( )

inlinevirtual

A name that describes the encoding of the signature value and key information in the signature dictionary.

Returns: a iText.Kernel.Pdf.PdfName which usually has a value either iText.Kernel.Pdf.PdfName.Adbe_pkcs7_detached or iText.Kernel.Pdf.PdfName.ETSI_CAdES_DETACHED.

◆ GetType()

virtual PdfName iText.Signatures.PdfSignature.GetType ( )

inlinevirtual

The type of PDF object that the wrapped dictionary describes; if present, shall be iText.Kernel.Pdf.PdfName.Sig for a signature dictionary or iText.Kernel.Pdf.PdfName.DocTimeStamp for a timestamp signature dictionary.

The type of PDF object that the wrapped dictionary describes; if present, shall be iText.Kernel.Pdf.PdfName.Sig for a signature dictionary or iText.Kernel.Pdf.PdfName.DocTimeStamp for a timestamp signature dictionary. Shall be not null if it's value is iText.Kernel.Pdf.PdfName.DocTimeStamp . The default value is: iText.Kernel.Pdf.PdfName.Sig.

Returns: a iText.Kernel.Pdf.PdfName that identifies type of the wrapped dictionary, returns null if it is not explicitly specified.

◆ IsWrappedObjectMustBeIndirect()

override bool iText.Signatures.PdfSignature.IsWrappedObjectMustBeIndirect ( )

inlineprotectedvirtual

Defines if the object behind this wrapper must be an indirect object in the resultant document.

Defines if the object behind this wrapper must be an indirect object in the resultant document.

If this method returns true it doesn't necessarily mean that object must be in the indirect state at any moment, but rather defines that when the object will be written to the document it will be transformed into indirect object if it's not indirect yet.

Return value of this method shouldn't depend on any logic, it should return always true or false.

Returns: true if in the resultant document the object behind the wrapper must be indirect, otherwise false.

Implements iText.Kernel.Pdf.PdfObjectWrapper< PdfDictionary >.

◆ SetByteRange()

virtual void iText.Signatures.PdfSignature.SetByteRange ( int[] range )

inlinevirtual

Parameters

cert	the byte[] representing the certificate chain

◆ SetContact()

virtual void iText.Signatures.PdfSignature.SetContact ( String contactInfo )

inlinevirtual

Sets the /ContactInfo value.

Parameters

◆ SetContents()

virtual void iText.Signatures.PdfSignature.SetContents ( byte[] contents )

inlinevirtual

Sets the /Contents value to the specified byte[].

Parameters

contents a byte[] representing the digest

◆ SetDate()

virtual void iText.Signatures.PdfSignature.SetDate ( PdfDate date )

inlinevirtual
