What is the origin of Skype?

The Skype application or program was designed in 2003 by the Danish Janus Friis and the Swede Niklas Zennistrom, They can be considered the original founders of the company, although they had the help of many more programmers who gave them a hand in the Estonian capital.

However, the application has always been free and has been able to be downloaded from the website of its owners at the beginning of the birth of the company.

However, in 2013 and after the purchase of Skype by Microsoft, the service was integrated into the Windows Live Messenger network, the messaging service that was previously known as MSN Messenger. Since then, its user interface is quite similar to the rest of the services that Microsoft offers within the Office suite.

Microsoft's acquisition of Skype It was valued at more than 8.500 million dollars, which positions this transaction as one of the most important in the technology sector, especially taking into account the dates on which they were carried out.

Is it safe to use Skype?

Since 2015, the NSA of the United States of America has officially monitored Skype calls. In addition, it uses a private VoIP telephony protocol. In this way and as a great difference between its rivals, Skype uses the P2P protocol, that is, it does not use an intermediate server between the users who carry out the communication.

Thereby Skype performs a great compression of the data it uses and that is precisely the advantage over most of its competitors, thus making it one of the most stable and best quality services among those that allow video calls.

To prevent any attack on the privacy of users Skype makes use of the 256-bit AES algorithm, encrypting the voice and files (such as messages) transferred. However, the paid version of the application has a security "plus", since it uses the RSA algorithm of 2048-bit to access the network and 1536-bit to establish the connection, which prevents man attacks. -in-the-middle.

We could definitely say that Skype is generally a video calling service secure enough for regular use.
