  CHAT ROOM WITH END-TO-END-ENCRYPTION  USING SOCKET PROGRAMMING PYTHON LEARNING: Socket programming Understanding TCP  Diffe hellman key exchange Encryption Tkinter Threading  What is  one way function?   There is no inverse  to this type of functions             Eg -     5 mod 2 =1 11 mod 2 = 1 25 mod 2 = 1 Any odd no. mod 2 = 1                Therefore, there are infinite possibilities  of odd numbers.                Hence, even if we  know remainder and divisor we cannot say what is dividend. (here we are not                   involving quotient, hence it is not possible to find the dividend .) Note: this is modulus property (g**A mod p)**B mod p =. (g**B mod p)**B mod p = (g **(A*B) mod) p mod p The same thing is done in diffe hellman key e...

Hosting A secure website with letsencrypt(free TLScertificate) Learning Outcomes: - Hosting a website - creating certificates  - understanding domain name resolution - CNAME, A, AAAA DNS records - Cloud computing Now lets start hosting our website. Understanding:: Step1:  Buying a domain  We have many websites to buy a domain(godaddy, domain.com, etc),  I used domain.com. Step2:   Lets go for hosting Here I used cloud computer, (sine, I have found it easy and convenient) or you can use your own infrastructure for hosting. Here I  used digitalocean droplet as my server. How to set up a server on digital ocean? Here are the  steps: 1. Go to digitalocean.com 2. Sign up 3. Create your project 4. After creating project, click on create a droplet.(here droplet is nothing but a virtualmachine) 5. Select the distribution and choose a plan, here I chose minimum plan.  6.
