Pointer cast constructor. Invokes Pointer(Pointer).

Method Detail

column_key

@StdString
public String column_key(@StdString
                                     String column_path)

column_key

@StdString
public BytePointer column_key(@StdString
                                          BytePointer column_path)

footer_key

@StdString
public String footer_key()

aad_prefix

@StdString
public String aad_prefix()

key_retriever

@SharedPtr
public DecryptionKeyRetriever key_retriever()

check_plaintext_footer_integrity

@Cast(value="bool")
public boolean check_plaintext_footer_integrity()

plaintext_files_allowed

@Cast(value="bool")
public boolean plaintext_files_allowed()

aad_prefix_verifier

@SharedPtr
public AADPrefixVerifier aad_prefix_verifier()

WipeOutDecryptionKeys

public void WipeOutDecryptionKeys()

Upon completion of file reading, the encryption keys in the properties will be wiped out (array values set to 0).

is_utilized

@Cast(value="bool")
public boolean is_utilized()

set_utilized

public void set_utilized()

FileDecryptionProperties object can be used for reading one file only. Mark FileDecryptionProperties as utilized once it is used to read a file as the encryption keys will be wiped out upon completion of file reading.

DeepClone

@SharedPtr
public FileDecryptionProperties DeepClone(@StdString
                                                      String new_aad_prefix)

FileDecryptionProperties object can be used for reading one file only. (unless this object keeps the keyRetrieval callback only, and no explicit keys or aadPrefix). At the end, keys are wiped out in the memory. This method allows to clone identical properties for another file, with an option to update the aadPrefix (if newAadPrefix is null, aadPrefix will be cloned too)

DeepClone

@SharedPtr
public FileDecryptionProperties DeepClone()

DeepClone

@SharedPtr
public FileDecryptionProperties DeepClone(@StdString
                                                      BytePointer new_aad_prefix)
