Today before the training session, when a mentor tried adding my website’s feed in dgplug planet , they told me there was an error, and they asked me to use the curl command on the website, so I did. curl https://techtrials.tech/feed I had a valid SSL certificate from Lets Encrypt, and my website ran on all the major browsers. However, the curl command threw the following error. curl: (60) SSL certificate problem: unable to get local issuer certificate More details here: https://curl.

As i have been using paid SSL certificates from namecheap for a long time, a friend of mine told me Letsencrypt issues you a free SSL certificate. A question raised in my mind that do certificates i pay for use better cryptography than free certificates?. After searching online i got to know “no! you can pay a certificate authority extra for an EV (“extended validation”) certificate, but that won’t give you better cryptography.
