    The following tables list the members exposed by StandardSecurityHandler.

    Public Properties
     NameDescription
    Public PropertyGets the access type granted by this StandardSecurityHandler, or null. This property is initialized when a document is loaded.  
    Public PropertyGets a value indicating whether the PDF has an owner password that is required to edit the document.

    This property is initialized when the document is loaded.

    Note that a document may be encrypted with an empty password, in which case HasUserPassword and HasOwnerPassword properties return false.

    Note also that, according to the PDF specification, if an owner password is not specified, then the user password should be used. GcPdf follows this rule, so if a PDF that was created using GcPdf with only a user password is loaded into GrapeCity.Documents.Pdf.GcPdfDocument, its AccessType will be AccessType.Owner, HasOwnerPassword will be true and HasUserPassword will also be true.  
    Public PropertyGets a value indicating whether the PDF has a user password that is required to open the document.

    This property is initialized when the document is loaded.

    Note that a document may be encrypted with an empty password, in which case HasUserPassword and HasOwnerPassword properties return false.

    Note also that, according to the PDF specification, if an owner password is not specified, then the user password should be used. GcPdf follows this rule, so if a PDF that was created using GcPdf with only a user password is loaded into GrapeCity.Documents.Pdf.GcPdfDocument, its AccessType will be AccessType.Owner, HasOwnerPassword will be true and HasUserPassword will also be true.  
    Public PropertyGets or sets the password required to change permissions of a PDF document as a string.

    The two properties OwnerPassword and OwnerPasswordBytes allow to define the password as a string or as an array of bytes.

    According to the PDF specification, a string password should be converted to an array of bytes using the system code page (if the standard security handler with revision 4 or less is used). In some environments the system code page is unavailable, so GcPdf cannot perform this conversion. If the password string only contains ASCII chars, this does not present a problem. But if the password string contains non-ASCII Unicode characters, it is up to the developer to perform the conversion and set the password using this property.

    Public PropertyGets the revision of this StandardSecurityHandler.
