org.apache.james.mime4j.storage.CipherStorageProvider
public class CipherStorageProvider
A StorageProvider that transparently scrambles and unscrambles the
data stored by another StorageProvider.
Example usage:
StorageProvider mistrusted = new TempFileStorageProvider(); StorageProvider enciphered = new CipherStorageProvider(mistrusted); StorageProvider provider = new ThresholdStorageProvider(enciphered); DefaultStorageProvider.setInstance(provider);

CipherStorageProvider for the given back-end
using the Blowfish cipher algorithm.
backend - back-end storage strategy to encrypt.
public CipherStorageProvider(StorageProvider backend,
java.lang.String algorithm)
CipherStorageProvider for the given back-end
and cipher algorithm.
backend - back-end storage strategy to encrypt.algorithm - the name of the symmetric block cipher algorithm such as
"Blowfish", "AES" or "RC2".| Method Detail |

public StorageOutputStream createStorageOutputStream()
throws java.io.IOException
StorageProviderStorageOutputStream where data to be stored can be
written to. Subsequently the user can call
toStorage() on that object to get
a Storage instance that holds the data that has been written.
StorageOutputStream where data can be written to.
java.io.IOException - if an I/O error occurs.
