                    throws IOException

Encrypts the given plain file to the given RAES file, using the provided ArchiveDetector to detect any archive files in its parent directory path except the files themselves, which are not recognized as archive files.

Throws:

IOException

decrypt

public static void decrypt(String raesFilePath,
                           String plainFilePath,
                           boolean strongAuthentication)
                    throws IOException

                           String plainFilePath,
                           boolean strongAuthentication,
                           ArchiveDetector detector)
                    throws IOException

Decrypts the given RAES file to the given plain file, using the provided ArchiveDetector to detect any archvie files in its parent directory path except the files themselves, which are not recognized as archive files.

Parameters:

strongAuthentication - If this is true, the whole contents of encrypted file get authenticated, which can be a time consuming operation. Otherwise, only the key/password and the file length get authenticated.
