Do you know everything beyond the SSL certificates? yes, it is extremely easy to learn those things though they are technical. Most of the website owners think that SSL certificates are just the part of the certificate thing but there is a lot more to it. The way we describe the Root certificate differs from the intermediate certificate.
SSL is a wide technology that end users may know little about it and having a bit idea about the root and intermediate certificate is widely important. Although web owners have SSL certificate, they don’t know much beyond the fact that they hardly need an SSL certificate to run their websites.
There are a lot of interesting things to know about SSL apart from the root chains, intermediate chains, and certificate chains. Although these topics seem to be boring, it is simple and straight forward if you master it and know the fact that how important it is for your website security.
What is a Root Certificate?
Root certificate ensures website security and is essential for any kind of websites. A root certificate is often known as the trusted root since it is the primary model of the trusted certificate that comes under the undergirds SSL/TLS. In general, the browser runs their own root certificates and in fact, every browser has its own root store. In short, the root store is a collection of existing root certificates which can be live on your device.
Hence, if any certificates that reach the browser with the default private key, it will be automatically trusted by their web browsers. The root certificate is the primary certificate and hence anyone can trust it without a second thought. All the trusted roots belong to the primary certificate thus the certificate authorities take care of the verification kinds of stuff. They are the primary organizations that verify, validate and issue SSL certificates.
What is the certificate chain?
Although the concept of a certificate chain seems to be a bit difficult, it would be interesting if you know the fact that the certificates are pressurized to be verified by the web browser. How does your web browser usually trust the SSL certificates?
Is it comes with any new mechanism that let the certificates to validate? No matter what type of site you are going through, your browser just have an eye on the SSL certificates and can perform the wonderful process to validate the certificates.
What role does the digital signature play?
once the browser recognizes the root certificate, it digitally signs an intermediate certificate, which transfers into the chain certificates. It can be trusted automatically when the signature comes from the trusted root certificates. The public key is associated with the SSL certificate and thus the browser receives the certificates. Later the digital signature will be decrypted and this process moves to the next certificate chain.
There is the main difference between Root CA and Intermediate CA. If a certificate Authority possesses more than one trusted roots, it is called a Root CA, which means that the trusted stores will be in essential browsers. Intermediate certificates are the one that issues intermediate root, which doesn’t require the browser’s trust stores.
Interestingly, SSL certificate comes under the types of digital certificate that combine both the web server and cryptographic keys, which can be used in TLS and SSL protocol to activate the safety session between web server hosting and browser.
CAs use these pre-installed Root Certificates to issue Intermediate Root Certificates and end entity Digital Certificates. The CA receives certificate requests, validates the applications, issues the certificates, and publishes the ongoing validity status of issued certificates so anyone relying on the certificate has a good idea that the certificate is still valid.
Once the Browsers and web devices trust the certificates, root certificate can store essential data into the root store. Moreover, the database of the approved certificates comes with pre-installed browser devices. Interestingly, the mobile carrier can focus and operate on its own root store, which makes it easy for them to finish the process.
CA will create a huge number of valid intermediate CA, which can be utilized to issue user end entity certificates.
