Description copied from class: Encryptor

Return a output stream for encrypted data.

Specified by:

getDataStream in class Encryptor

Parameters:

dir - the node to write to

Returns:

encrypted stream

Throws:

IOException

GeneralSecurityException

getDataStream

public org.apache.poi.poifs.crypt.binaryrc4.BinaryRC4Encryptor.BinaryRC4CipherOutputStream getDataStream(OutputStream stream,
 int initialOffset)
                                                                                                  throws IOException,

Throws:

IOException

GeneralSecurityException

setChunkSize

public void setChunkSize(int chunkSize)

Description copied from class: Encryptor

Sets the chunk size of the data stream. Needs to be set before the data stream is requested. When not set, the implementation uses method specific default values

Overrides:

setChunkSize in class Encryptor

Parameters:

chunkSize - the chunk size, i.e. the block size with the same encryption key

copy

public BinaryRC4Encryptor copy()

Specified by:

copy in class Encryptor
