◆ Initialize()

FSDK.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 FSDK.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_dataA custom encrypt data object.
[in]callbackA valid FSDK.CustomSecurityCallback object, which is inherited and implemented by user for their own encryption and description algorithm. It should not be null.
[in]encrypt_infoThe 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.
