What Is HTTPS? How Does It Work? Automate With cert-manager And Let's Encrypt
Source: YouTube · DevOps & AI Toolkit · published Dec 5, 2022 · 17:54
HTTPS provides secure web communication through encryption and authentication, and tools like cert-manager make it easy to automate certificate management 0:26.
Key Takeaways:
• HTTP transmits data in plain text, making it vulnerable to eavesdropping, while HTTPS solves these security issues 0:26
• HTTPS uses TLS/SSL with public-private key encryption: servers keep private keys secret while sharing public keys with clients 2:29
• Certificate Authorities verify server identities, ensuring clients are communicating with legitimate servers 6:36
• In Kubernetes, cert-manager combined with Let's Encrypt automates certificate issuance and renewal 11:21
There's no excuse not to implement HTTPS for web applications given the security benefits and ease of automation with modern tools 17:03.

did you ever wonder why we use https instead of http do you know how the https protocol works and how about full automation of all the tasks related to https keys and certificates [Music] all Communications occurs over HTTP is happening in plain text as a result such communication can be easily sniffed somebody can relatively easily find out what is the information flowing between a client and a server so in a more simplistic way here's how it works we have a client let's say a laptop that goes to DNS server and asks something like hey where is silliedemo.com or any other domain and the DNS server responds with an IP like 167 23 and so on and so forth now with that IP the client forwards actually sends a request to the destination because that's the destination server or that's the destina…
