is Skype safe?

Skype uses an End-to-end encryption method to ensure the security of information. Skype encrypts information (voice, instant messaging, file) before it is sent, decrypts it when it is received, and is not likely to be tapped halfway through other nodes, even in the process of data transfer.

Skype uses digital signatures to ensure that user data stored in Peer-to-peer networks is not tampered with. Because Skype uses peer-to-peer technology, user data is mainly stored in peer-to-peer networks, which are retrieved from public networks when users perform search operations. This must ensure that the data stored in the public network is reliable and has not been tampered with. Skype uses digital signatures to store and user-related data in the public directory, ensuring that data cannot be tampered with.
