Abstract: Snowden's whistleblower from the last year made people more aware of the fact that we are living in the Internet surveillance era. Privacy of Internet communication has been disrupted. In this paper, application for privacy protection in chat communication, named CryptoCloak, is presented. CryptoCloak provides privacy protection for chat communication. Encrypted communication is masked with dynamic cheap chat conversation. Communication made this way is not point of interest for mass surveillance spying engines. For implementation of the CryptoCloak, Facebook Messenger API is used. Diffie-Hellman key exchange is done in clandestine manner - instead of sending uniform sequence of numbers, sentences are sent. Current version provides encryption/decryption mechanism for the chat communication using strong symmetric algorithm AES in CBC mode. 256 bits of Diffie-Hellman exchanged key are used for AES-CBC.
