Main article: Skype was claimed initially to be a, with one of its early web pages stating 'highly secure with end-to-end encryption'. Security services were invisible to the user, and encryption cannot be disabled. Skype reportedly uses publicly documented, widely trusted encryption techniques: for key negotiation and the to encrypt conversations.

However, it is impossible to verify that these algorithms are used correctly, completely, and at all times, as there is no public review possible without a protocol specification and/or the app source code. Skype provides an uncontrolled registration system for users with no proof of identity. Instead, a free choice of nicknames permits users to use the system without revealing their identities to other users. It is trivial to set up an account using any name; the displayed caller's name is no guarantee of authenticity.

Some researchers have been able to the traffic so that it is identifiable even after passing through an.

The Microsoft query used the full URL supplied in the IM conversation and was generated by a previously undocumented security service.

Security experts speculate the action was triggered by a technology similar to Microsoft's SmartScreen Filter used in its browsers. The revealed that agencies such as the and the have the ability to eavesdrop on Skype, including the monitoring and storage of text and video calls and file transfers. The surveillance program, which requires authorization, reportedly has allowed the NSA unfettered access to its data center supernodes. According to the leaked documents, integration work began in November 2010, but it was not until February 2011 that the company was served with a directive to comply signed by the attorney general, with NSA documents showing that collection began on 31 March 2011.

On 10 November 2014, Skype scored 1 out of 7 points on the 's secure messaging scorecard. Skype received a point for encryption during transit but lost points because communications are not encrypted with a key the provider doesn't have access to (i.e.

The communications are not ), users can't verify contacts' identities, past messages are not secure if the encryption keys are stolen (i.e. The service does not provide ), the code is not open to independent review (i.e. The code is not ), the security design is not properly documented, and there has not been a recent independent security audit., and also scored 1 out of 7 points.
