 THE THREE MODULES

• STEGANOGRAPHY

• CRYPRTOGRAPHY

• FILE SPLITTER
STEGANOGRAPHY
• Steganography is the art and science of
  writing hidden messages in such a way that
  no one apart from the intended recipient
  knows of the existence of the message; this is
  in contrast to cryptography, where the
  existence of the message itself is not
  disguised, but the content is obscured
  * The advantage of steganography over cryptography
alone is that messages do not attract attention to themselves,
to messengers, or to recipients. An unhidden coded message,
no matter how unbreakable it is, will arouse suspicion and
may in itself be incriminating, as in some countries encryption
is illegal.


  * Steganography uses in electronic communication
include steganographic coding inside of a transport layer,
such as an MP3 file, or a protocol, such as UDP.
CRYPRTOGRAPHY
• "cryptography" referred almost
  exclusively to "encryption", the
  process of converting ordinary
  information ("plaintext") into an
  unreadable "ciphertext".
  "Decryption" is the reverse
  process, recovering the plaintext
  back from the ciphertext
 Symmetric-key algorithm
• Symmetric-key algorithms are a class of algorithms for
  cryptography that use trivially related cryptographic keys
  for both decryption and encryption.
• The encryption key is trivially related to the decryption
  key, in that they may be identical or there is a simple
  transform to go between the two keys. The keys, in
  practice, represent a shared secret between two or more
  parties that can be used to maintain a private information
  link.
• Other terms for symmetric-key encryption are single-key
  and private-key encryption. Use of the latter term can
  sometimes conflict with the term private key in public key
  cryptography.
     FILE SPLITTER
• This File Splitter is used to split DAT files
  of all sizes.
• It can split a DAT file in N number of
  pieces as desired by the user.
• It helps in sending and receiving large files
  as they can be transferred in pieces.
• Can also be a weapon of data security.
        FILE JOINER
• Its is used to join the files splitted by
  the splitter.
• The joiner takes the source and then
  goes to the destination to fix files.
• All files splited by the file splitter are
  joined by the file joiner.
