Let's Create a Secure AES-Encrypted Video Chat Noone Can Decipher
#cryptology, #cryptography, #cryptanalysis
In this video, we show how to create a secure (AES-encrypted) video (and audio) chat using CrypTool 2. We use two different methods to establish a common secret key:
1) Pre-shard key (based on a password) using PKCS5
2) Establishing a common secret using Diffie-Hellman key exchange
We first discuss why communication should be end-to-end encrypted over the Internet. Then, we show the basic ideas of (1) and (2). Finally, we live demonstrate how to create a chat using AES with two different computers. We also dicuss briefly, why diffie-hellman is "not enough" to actually create a secure communication between two parties.
If you want to know how the Diffie-Hellman key exchange actually works, please have a look at my video about that: https://youtu.be/2Uz9hdhcFv8
