The EncryptionMethod property is a free form string indicating the algorithm or tool used to encrypt the logical file. If it is not possible (or not desired) to describe the encryption scheme (perhaps for security reasons), use the following words: \"Unknown\" to represent that it is not known whether the logical file is encrypted or not, \"Encrypted\" to represent that the file is encrypted but either its encryption scheme is not known or not disclosed, and \"Not Encrypted\" to represent that the logical file is not encrypted.
