How Do You Check your SSL/TLS Functioning Mechanism?

July 21, 2017 | By John Britas

As the connected world is moving fast and adopting the encrypted world the TLS certificate is becoming a mandatory for all. Unlike earlier the process is simple now, and sometimes free.

Inorder to get a SSL certificate we need to send a requisite for Certificate Signing Request (CSR) to the CA (Certificate Authority). In return the owner will be asked to provide documents that prove his/her ownership of the domain. Most of the time the ownership is proved by a setting a DNS text record.

Once the claim is verified and the CA is satisfied with the proof, they will issue the certificate, which is then installed on the server and your website/domain gets a green padlock with HTTPS in the address bar.


There are two type of keys – Private and Public. The certificate used for HTTPS are public document, which is sent to user who wants to connect with our site. What restricts other individuals from using our certificate is that they do not have the private key. When a secure connection is established between the browser and server, it checks the server for private key for certificate. If the hacker manages to steal your private key then, it may be a different game. If the hacker takes away your private key he can prove that they are you. It was noted how people accidentally give away their private keys.

The only way to stop the hacker from claiming your certificate is by contacting the CA authority and revoking the certificate.

One of alternate things that we need to consider while we’re on the point of renouncement is rebel endorsements. In the event that some person figures out how to trade off a CA or generally gets a testament that they should have, how are we expected to know?.

Certificate Revocation

Once your certificate is compromised with the attacker can abuse it. Once the certificate is flagged ‘revoked’ the browser will not trust the content of the website, despite the fact that it’s legitimate. The owner has asked for revocation and no customer ought to acknowledge it.

As it currently stands there is a real problem, we can’t revoke certificates if someone obtains ouAs it reads we have a real issue in hand, we can’t revoke certificate if your private key is hacked or taken by somebody. Just think what will happen if you certificate is stolen. Only one thing you need to do is to try and cut off the effect of a bargain.

If I somehow managed to break a CA at this moment and get an endorsement for your site without informing you, you wouldn’t ever pick up regarding it unless it was broadly announced. You could even have an insider danger and somebody in your association could get authentications without adhering to the correct inward procedures and do with them however they see fit. We require an approach to have 100% straight forwardness and we will soon, Certificate Transparency.


CT is another necessity that will be compulsory from ahead of schedule one year from now and will require that all endorsements are signed in an open log if the program is to believe them. You can read the article for more subtle elements on CT yet what will for the most part happen is that a CA will log all endorsements it issues in a CT log.


Instead of three years go for one year or even less. Let’s Encrypt and issue certificates that are valid for ninety days! When the expiry of the certificate is decreased, then one need not have to worry at large, since the attacker has less time to abuse before the certificate gets expired.

Rather than three years go for one year or even less. Encrypt and issue certificate that are enough for 90-days! With a lifetime going down on your certificate, you have to a less problem and the attacker will not have enough time to before the certificate expires.
