Description copied from class: EncryptionHandler

This method is called just before the PDF is read in. It is expected that this method will read various parameters from the Encrypt dictionary by way of the various get... methods, and use them and the value of EncryptionHandler.getFileId() to set its internal state so that it's ready to start decryption. It may throw an IOException if these parameters are invalid, in which case the document cannot be read.

Overrides:

prepareToDecrypt in class StandardEncryptionHandler

Throws:

IOException
