SKYPE Overview
It aims to connect users via text (instant messaging), voice or video. One of its great strengths is precisely voice communication (IP) between users who have Skype, which are completely free calls anywhere in the world. It also makes calls at very low cost paid between computer and landline or cell phone.
You can use the following form to contact or generate calls from anywhere in the world:
* Communication by text from Skype user to Skype users via PC and the internet (free).
* Communication video from Skype user to Skype user via PC and the internet (free).
* Voice communication from user to user Skype Skype via PC and the internet (free).
* Communication by video conference or conference from Skype user to Skype users via PC and the internet (free).
* Voice communication from Skype users via PC and Internet to fixed telephone (monthly and annual contract at a very low cost).
* Voice communication from Skype users via PC and internet phone (monthly and annual contract at a very low cost).
* Communication data (text and graphics) from Skype users via PC and internet fax landline or PC fax (monthly and annual contract at a very low cost).
* Voice communication from your landline phone number to a Skype user Pc (monthly and annual contract at a very low cost).
* Voice communication from cell phone to Skype phone number of a user of Pc (monthly and annual contract at a very low cost).
* Voice communication from fixed telephone and cellular phone number of Skype voicemail for a PC user (monthly and annual contract at a very low cost).
* Communication by fax from a fax phone number telephone network to a user's Skype Pc (monthly and annual contract at a very low cost).
Communication by phone and text forwarding from a landline phone or cell phone to a Skype user on a PC (monthly and annual contract at a very low cost).

When you initiate a call is established a direct connection with the person. The program has been developed in Pascal using Delphi and later has been ported to GNU / Linux based on the Qt libraries.
Security
It uses the AES algorithm A 256-bit to encrypt voice, file transfer or an instant message. For the paid version uses the RSA 2048-bit to access voicemail and 1536-bit for negotiation when the connection. They use an asymmetric key attacks thus avoiding man-in-the-middle.
