createContentCipher

public static java.lang.Object createContentCipher(boolean forEncryption,
                                                   CipherParameters encKey,
                                                   AlgorithmIdentifier encryptionAlgID)
                                            throws java.lang.IllegalArgumentException

Create a content cipher for encrypting bulk data.

Parameters:

forEncryption - true if the cipher is for encryption, false otherwise.

encKey - the basic key to use.

encryptionAlgID - identifying algorithm OID and parameters to use.

Returns:

a StreamCipher or a BufferedBlockCipher depending on the algorithm.

Throws:

java.lang.IllegalArgumentException

createOutputStream

public static CipherOutputStream createOutputStream(java.io.OutputStream dOut,
                                                    java.lang.Object cipher)

Return a new CipherOutputStream based on the passed in cipher.

Parameters:

dOut - the output stream to write the processed data to.

cipher - the cipher to use.

Returns:

a BC CipherOutputStream using the cipher and writing to dOut.
