SSL is an acronym for Secure Sockets Layer. It is a protocol that provides a secure connection between two computers over the Internet. It uses encryption to protect data during transmission.

Encryption is a process of transforming readable data into an unreadable format. This prevents anyone who intercepts the data from being able to read it. SSL uses a public key and a private key for encryption.

  • The public key is used to encrypt data.
  • The private key is used to decrypt data.

Data that has been encrypted with the public key can only be decrypted with the private key. This makes it impossible for someone who intercepts the data to read it unless they have the private key. The key question you might ask is” Is SSL secure.” This article will answer this question and hopefully a few more that you might have.

Why do you need an SSL for your website?

SSL is used to protect sensitive information such as credit card numbers, login credentials, and personal information. When you enter sensitive information into a web form, the data is encrypted with the public key before it is transmitted. The data can only be decrypted with the private key. This ensures that the data is protected from anyone who may try to intercept it.

SSL is also used to authenticate a website. When you visit a website that has one, the website’s identity is verified with the public key. This ensures that you are visiting the website that you think you are and not a imposter site.

You should always look for the https:// in the URL of a website before entering any sensitive information. This indicates that the website is using SSL and your data will be encrypted.

What are its features?

SSL is a protocol that provides privacy, authentication, and data integrity for Internet communications. It is the standard for securing connections between web browsers and web servers. It is also used for other applications such as email, instant messaging, and voice-over-IP (VoIP). Additionally, it uses a combination of public-key and symmetric-key cryptography to encrypt data being sent over the Internet. Therefore, finally, it also authenticates the identity of the website and the server, ensuring that you are connecting to the s

Some features of SSL include:

  • Encryption: This is the main feature. It uses a combination of public and private keys to encrypt data being sent over the Internet.
  • Authentication: SSL also authenticates the identity of the website and the server. This ensures that you are connecting to the right site and not a fake one.
  • Data integrity: SSL protects against data tampering. It checks that the data being sent has not been modified in transit.

How does SSL work?

SSL works by using a combination of public and private keys to encrypt data being sent over the Internet. The public key is used to encrypt the data, and the private key is used to decrypt it. This is known as an “SSL handshake.” The data is encrypted using a mathematical algorithm, and the private key is used to decrypt it.

When you connect to a website, the server sends you its SSL certificate. This certificate contains the public key that is used to encrypt the data. The browser then uses this public key to encrypt the data before sending it to the server. The server decrypts the data using the private key and sends it back to the browser.

The key function is to protect sensitive information, such as credit card numbers and login credentials. When data is encrypted, it is difficult for anyone to intercept and read it.

What is an SSL certificate?

Every website today is required to have an SSL certificate

An SSL certificate is a digital certificate. The SSL protocol encrypts data being sent over the Internet. The certification authority (CA) issues the SSL certificate. In order for a website to use this SSL, it must have a valid SSL certificate. This certificate is issued by a certificate authority and contains the website’s public key. The website’s private key is kept secret and is used to decrypt the data that is encrypted with the public key.

SSL is used by millions of websites to protect their online transactions. It is also used by email servers to protect the privacy of email messages.

Types of SSL?

There are three types of SSL certificates:

Domain Validated (DV):

This type of certificate is the easiest and quickest to get. The CA verifies that you own the domain, but does not verify your identity or any other information about your organization.

Unfortunately, the drawback is that since DV certificates don’t require any vetting, they offer the least amount of trust. They’re fine for personal websites and internal company sites that are not handling sensitive information.

Organization Validated (OV):

To get an OV certificate, the CA will verify your organization’s identity, as well as making sure you own the domain. The CA will also check to see if your organization is registered with the Better Business Bureau (BBB) or something similar.

OV certificates offer more trust than DV because the CA has verified not only your domain ownership, but also your organization’s identity. This type of certificate is good for public-facing websites that need to build trust with their visitors.

Extended Validation certificates (EV SSL)

To get an EV certificate, the CA will do a thorough investigation of your organization. This includes verifying your business registration, contacting a company representative, and making sure you have a physical address. The CA will also check to see if your organization is in good standing with the BBB or something similar.

EV certificates offer the highest level of trust and show your visitors that you’re a legitimate business. They also trigger the green bar in browsers, which can increase conversions.

If you’re running an ecommerce store or handling sensitive customer information, EV SSL is a good choice.

There are some variations as well that apply the authentication type with feature sets to secure unique web environments:

Wildcard SSL certificates:

These certificates secure multiple subdomains under a single domain name. This helps if you have a large website with many pages.

  • Multi-domain SSL certificates: These certificates secure multiple domain names. They’re perfect for organizations with multiple websites or businesses that want to increase their online presence.
  • UC/SAN SSL certificates: These certificates secure multiple domain names and subdomains. They’re perfect for organizations with multiple websites or businesses that want to increase their online presence.
  • Unified Communications Certificate (UCC): This type of certificate secures Microsoft Exchange and other Microsoft Communications Server environments. It secures multiple domain names and subdomains.

How can I get an SSL certificate for my business?

Organizations can purchase SSL certificates from a number of different vendors. Once you have decided on a vendor, you will need to generate a Certificate Signing Request (CSR) from your server. The CSR is then sent to the vendor. The vendor uses it to generate a unique certificate for your organization.

When you receive the certificate, you will need to install it on your server. Once the certificate is installed, your server securely communicates with clients using SSL.

The cost of an SSL certificate can vary depending on the type of certificate and the vendor you purchase it from. Generally, however, SSL certificates are very affordable and are well worth the security they provide.

Let’s see the process in brief:

  • The browser / server attempts to connect to an SSL-secured website (i.e., a web server).
  • The browser / server asks the web server to identify itself.
  • Then, the web server sends a copy of its SSL certificate. This tells any browser that connects to it about interception.
  • The browser or server determines whether or not it trusts the SSL certificate. If it does, it notifies the web server.
  • After the web server has verified that you’re who (and what) say in your browser, it responds with a digitally signed acknowledgment. This allows for an SSL encrypted session between client and site-meaning all data is safe!
  • The browser or server and the web server exchange encrypted data.

What is the difference between SSL and TSL?

SSL and TSL (Transport Layer Security) are two different protocols that provide security and privacy for data transmitted over the internet.

Both of them use encryption to protect data transmitted over the internet. However, TLS is more secure than SSL because it uses stronger encryption algorithms. TLS mainly finds usage in e-commerce and web applications to protect sensitive data, such as credit card information and login credentials.

Benefits of SSL

What does an SSL certificate mean for a website?

There are many benefits of using SSL, including:

  • Ensures that data exchanged between the browser and web server is encrypted and thus private
  • Prevents hackers from intercepting and tampering with data transferred between the browser and web server
  • Helps build trust with website visitors by showing that the site is legitimate and not a phishing scam
  • Reduces the chance of browser warnings appearing when visitors attempt to access your website

Conclusion

To conclude, SSL is a security protocol that encrypts data exchanged between a web browser and server. It is important for e-commerce and web applications as it protects sensitive information, such as credit card details and login credentials.

Every website should have SSL installed, especially if the site collects any kind of user data. For all our clients here at Pixel Street, the websites we design have it installed on them and this ensures that their websites are secure. Contact us today to learn more!
