Detailed Description

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

Class FSDK.StdSecurityHandler is used for password encryption.
Class FSDK.CertificateSecurityHandler is used for certificate encryption.
Class FSDK.DRMSecurityHandler is used for DRM encryption.
Class FSDK.CustomSecurityHandler is used for custom encryption.
Class FSDK.RMSSecurityHandler is used for RMS encryption.

To set a security handler to a PDF document, please call function FSDK.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 FSDK.PDFDoc.SetSecurityHandler.

Member Function Documentation

◆ GetSecurityType()

FSDK.SecurityHandler.GetSecurityType ( )

inline

Get the encryption type of current security handler.

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

◆ IsEmpty()

FSDK.SecurityHandler.IsEmpty ( )

inline

Check whether current object is empty or not.

When the current object is empty, that means current object is useless.

Returns: true means current object is empty, while false means not.

Enumeration for Encryption Algorithm.

Values of this enumeration should be used alone.Not use encryption algorithm.
