Detailed Description

Class SecurityHandler is the base class that represents a security hander used for encrypting PDF document. It has following derived classes:


Class StdSecurityHandler is used for password encryption.
Class CertificateSecurityHandler is used for certificate encryption.
Class DRMSecurityHandler is used for DRM encryption.
Class CustomSecurityHandler is used for custom encryption.
Class RMSSecurityHandler is used for RMS encryption.
To set a security handler to a PDF document, please call function pdf::PDFDoc::setSecurityHandler, then the security handler will take effect in later saving process. To get the security handler used for a PDF document, please call function pdf::PDFDoc::setSecurityHandler.

Constructor, with another SecurityHandler object.

Parameters
otherAnother SecurityHandler object.

Member Function Documentation

◆ getSecurityType()

int com.foxit.sdk.pdf.SecurityHandler.getSecurityType ( )

Get the encryption type of current security handler.

Returns
The encryption type. If current SecurityHandler object does not represent any specified type of security handler, it would return e_EncryptUnknown.

◆ isEmpty()

boolean com.foxit.sdk.pdf.SecurityHandler.isEmpty ( )

Check whether current object is empty or not.
