You can read more about KRACK attacks here. As we’ve seen with the latest KRACK attacks, it is entirely possible to decrypt a victim’s https traffic. But, SSL is not as safe as we originally thought it was.

Therefore, we refer to TLS as SSL version 3 (SSLv3). These days, however, most of our Web servers are utilizing Transport Layer Security (TLS 1.2), which is an updated version of SSL 3.0. This is because https uses the Secure Sockets Layer (SSL) encryption scheme to pass keys between two parties over the Internet. The server (my IP camera) - now knowing what our client (the browser) supports - picks a TLS version, cypher suite and ellipsis it wants to use - Supported Version: TLS 1.Hypertext Transfer Protocol over SSL (https) is pretty decent security. In here our client - in this case our web-browser - states that it knows TLSv1.3 and TLSv1.2 and insists on the Elliptical Curve Diffie Hellman Ephemeral ( ECDHE) Key Exchange and supports 16 different cypher suits for the data encryption: The conversation starts with a TCP handshake that is followed by a Client Hello. Select a 'conversation' and use it to filter our log file: To deeper analyze our now decrypted data we can open the Conversations window:

The entries are now successfully decrypted and what showed up as encrypted application data before can now be identified as a TLS handshake: Here you need to add the log file created earlier: Right-click the package and open the Transport Layer Security Preferences: Right click one of the Client Hello packages and select to follow the TCP Stream:Ĭlose the opening window and select the first package that contains Application Data after the hello and cypher negotiation:
