SSL Certificates-A Powerful Tool for Virtual Authentication
Recently updated on November 18th, 2021 at 10:32 am
Many of us often hear the term “SSL certificate”, but few know what it really is or how it works. It’s also clear that this may not be the case, as few people really know what a Certificado SSL is.
Note its importance or importance in the world of computers and the Internet.
In particular, an SSL certificate called Secure Socket Layer Protocol Certificate was developed by Netscape to add a security element to transactions between browsers and web servers.
The protocol uses a third-party certificate authority to identify transactions at both ends.
If so difficult to understand, a website SSL certificate in a lay language is like a driver’s license issued by a passport or a known trusted source. As a certificate authority.
To spread a basic understanding of SSL certificates through real-world examples, imagine someone sending an email via a regular postal system in an envelope.
Since there is no security element, anyone with access to the envelope can easily retrieve its contents and, if it seems worthwhile, own or modify it.
Simply put, SSL certificates encrypt virtual transactions, transitions, or data exchanges over the Internet to make them completely secure.
SSL certificate workflow:
This is how the Secure Socket Layer Protocol Certificate works.
A secure page is requested by the browser-https: // normal
The public key is sent from the web server along with the certificate
The browser then verifies that the certificate was issued by a trusted source, that the certificate is valid, and that it is associated with the connected website.
During validation, the public key is basically used by the browser to encrypt the random symmetric encryption key, which is encrypted and sent to the server at the required URL along with other encrypted http data.
The symmetric key is then decrypted by the web server using its private key, which then decrypts the http data and URL using the symmetric key.
The requested html document and http data are sent by a web server encrypted with a symmetric key.
And finally, the http data and html document are decrypted by the browser using the symmetric key and the information is displayed.
For those with very little technical knowledge, the above workflow may seem a bit complicated.
However, to understand this very clearly, there are some things you need to understand, such as private / public keys, certificates, symmetric keys, cryptographic algorithms, hashes, signatures, passphrases, public key infrastructure, etc. There is a technical concept.
SSL certificate type:
There are many types of SSL certificates, so not all are the same when compared to each other. When it comes to SSL protection on your website, it’s important to consider the type of certificate you’re getting. Since this is a security application, it basically serves two main purposes.
Identify your business website
Encryption of sensitive information contained on your website
SSL certificates come in a variety of pricing ranges from $ 30 to $ 1,000 per year, and the cost of obtaining SSL protection depends on the type of certificate you actually use.
Listed below are the main types of SSL certificates and their features.
Dedicated SSL Certificates: These types of certificates are specially assigned to your website’s unique domain name. As a result, dedicated SSL certificates often require a unique domain name, and even subdomains cannot be shared with multiple domain names. These types of certificates are usually the most expensive.
