## Constructor & Destructor Documentation

## ◆ CustomSecurityHandler()

def FoxitPDFSDKPython2.CustomSecurityHandler.CustomSecurityHandler | ( |  | other | ) |

Constructor, with parent class object.

Parameters

  [in] | other | Parent class object.

## Member Function Documentation

## ◆ Initialize()

def FoxitPDFSDKPython2.CustomSecurityHandler.Initialize | ( |  | encrypt_data,
|  |  | callback,
|  |  | encrypt_info
| ) |  |

Initialize current custom security handler.

If this function is successfully, Foxit PDF SDK will take over the input security callback object and user should not release this callback object directly anymore; otherwise unexpected crash may occurs later.
Foxit PDF SDK may release the security callback object by callback function FoxitPDFSDKPython2.SecurityCallback.Release , when current security handler is released and find that the callback object has not been used by other object. So, user is recommended not to use the security callback object any more, after current security handler is released.

Parameters

  [in] | encrypt_data | A custom encrypt data object.
  [in] | callback | A valid CustomSecurityCallback object, which is inherited and implemented by user for their own encryption and description algorithm. It should not be null.
  [in] | encrypt_info | The encryption information,which will be stored to document encryption dictionary. This can be an empty string. Default value: an empty string.

Returns
  true means success, while false means failure.
