4. The Bottom Line
I started as a skeptic. I thought the system would be easy to defeat. However, my confidence in the Skype grows daily. The more I find out about it, the more I like. ...
The designers of Skype did not hesitate to employ cryptography widely and well in order to establish a foundation of trust, authenticity, and confidentiality for their peer-to-peer services. The implementers of Skype implemented the cryptographic functions correctly and efficiently. As a result, the confidentiality of a Skype session is far greater than that offered by a wired or wireless telephone call or by email and email attachments.
Beyond errors in the cryptosystem, I have also looked for back doors, Trojans, overreaching ,debugging, facilities, etc. I did not find any hints of malware in the portions of the Skype code I reviewed.
