Abstract
The present invention provides a method for transferring encrypted information from one storage area to other storage area wherein cryptographic data protection scheme having protection attributes are applied on the data. A crypto container having cryptographic properties represents cryptographically protected data. The attributes that have been attached to the container at the time when data is added or removed from the container determine the scheme of data protection being applied. Crypto container can be converted or serialized for storage or transmission, here the conversion spread only to the protected data parts which possibly includes crypto containers in protected form but may not the attached crypto attributes. These attributes must be stored or transmitted in another form.
