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.

Member Enumeration Documentation

◆ CipherType

Enumeration for Encryption Algorithm.

Values of this enumeration should be used alone.

Enumerator
e_CipherNone 

Not use encryption algorithm.

e_CipherRC4 

Use RC4 encryption algorithm, with the key length between 5 bytes and 16 bytes.

e_CipherAES 

Use AES encryption algorithm, with the key length be 16 bytes (as AES-128) or 32 bytes (as AES-256, only supported in PDF 2.0).

Member Function Documentation

◆ GetSecurityType()

PDFDoc.EncryptType foxit.pdf.SecurityHandler.GetSecurityType ( )
inlinevirtual

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()

bool foxit.pdf.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.
