Introduction to SSL Certificate

Secure Sockets Layer (SSL) is a security protocol designed to encrypt communication between an internet browser & a website. SSL certificates are small data files that bind a cryptographic key to an organization’s details. Installing on a web server activates the HTTPS protocol, which secures connections from web server to client browser.

Benefits of SSL Certificate

An SSL Certificate is a digital verification that confirms the identity of a website, as well as scrambles information sent to the server using SSL tech. Encryption is the process of making data unrecognizable and only able to be seen with a secret key. It’s important in protecting details such as credit card numbers, social security numbers & login credentials.

When you install an SSL Certificate to your web server, it turns on the padlock and “https” protocol, allowing secure connections from the web to a browser. SSL is usually used to protect credit card transactions, data transfers & logins. Nowadays, it’s commonly used when accessing social media sites.

Using an SSL Certificate has lots of advantages:

• Gives customers assurance that your website is protected from malware or phishing attempts;
• Raises the ranking of your website on search engines;
• Safeguards sensitive information like financial records & login credentials;
• Enhances customer faith in your website, showing them their data is safe;
• Offers encryption for the sending of information between two computers over a network.
• Save your website from hackers

Types of SSL Certificate

SSL Certificates secure data & transactions on websites. All types do the same job: encrypt traffic between website & customer’s browser. No one can intercept it to steal info.

Five main types of SSL Certificates:

1. Domain Validated (DV) – Only need email verif. or file-based validation from CA. Issued quickly.

2. Organization Validated (OV) – ID docs required. CA needs to review them. Takes more time than DV.

3. Extended Validation (EV) – Most trusted. Rigorous vetting processes. Ideal for ecommerce sites.

4. Wildcard Certificates* – Protect unlimited subdomains with one SSL certificate. Saves time & money compared to individual certs.

Tips for Choosing SSL Certificate

Choosing the right SSL certificate can be intimidating. It’s important to pick one that fits your security needs & budget. Here are some tips to help you out:

1. Analyze your security needs: Select an SSL certificate based on the encryption level you need. There are various levels of encryption. Choose one that provides enough security & fits your budget.

2. Pick a provider and plan: From a list of providers, select one that offers good customer service & competitive prices. Compare various subscription lengths and select the one that works for your budget. Also, check the warranty amount they offer in case something goes wrong with the certificate.

3. Check compatibility and features: Most browsers are compatible with standard certificates. However, make sure that the certifications work across all required servers & check any additional features (e.g., EV logo).

4. Compare prices: Look at the cost of installation, support, expiration date, etc. They could differ among providers.

5. Get a backup: It’s a good idea to buy an extra copy in case of data breach or malfunctioning servers. Purchase an extra copy at the time of renewal/purchase.

Free SSL Certificate

A Secure Sockets Layer (SSL) certificate is a digital certificate issued by a certified authority. It enables a website to have an encrypted connection with the web browser. This makes it secure for users to transfer data. Information like passwords, payment details & other personal data remain private.

Free SSL certificates are available from providers such as Let’s Encrypt & Cloudflare. These certificates only require domain verification; no extra validation process is needed. Although they are free, they may not provide full protection like paid SSL certificates. Now a days many hosting companies are also providing free SSL certificate with their shared and business hosting plans.

When selecting a free SSL certificate, remember that many do not have advanced features such as secure server seals & malware scanning services like SiteLock. Also, free certificates usually have shorter validity periods than premium versions. The period may even be shorter than 90 days.

It’s important to note that free certificates may have less website encryption than paid ones. So if high levels of security are needed, it’s best to pay for a longer-term SSL certificate from a reliable CA. Don’t choose a no-cost option without researching its features first.

How to Install an SSL Certificate?

Installing an SSL Certificate is vital for setting up an online presence, whether it be a website, email server or any other service. This certificate provides secure communication between the online service & customers/users by encoding data passed between them. This encrypted connection helps defend sensitive info, like usernames, passwords, credit card numbers, etc., from being obtained by bad guys.

A Certificate Authority (CA) is responsible for verifying the company requesting the certificate, then issuing a signed one for its domain name(s). These CAs are viewed as trustworthy by most browsers & OSs.

Once you possess an SSL from a trusted source, you must install it on your web server. This generally involves these steps:

1. Generate a Certificate Signing Request (CSR)
2. Submit the CSR to the CA
3. Receive the signed Certificate
4. Install the Certificate on your web server
5. Configure the web server for SSL/TLS
6. Test if it all works correctly

The process can differ depending on the type of SSL & web server, so it’s best to refer to the provider’s instructions for installation, to guarantee optimal security & compatibility.

Common SSL Certificate Errors

SSL (Secure Socket Layer) certs are documents on your web server. They provide a secure connection between visitors & your website. When visitors open a website, they are used to encrypt info & authenticate the server’s identity.

SSL errors occur due to incorrect configurations, server problems, or expired certs. It’s important to understand them & take steps to resolve them.

Common SSL Errors:

• Invalid Certificate: Occurs when an old or invalid cert is linked to a website, causing an error when trying to connect.
• Mismatched Domain Name: Occurs when the URL entered in the browser address bar is different from what’s on the SSL cert. This is often due to entering www in front of the domain name not specified in the cert.
• Outdated Software: Browsers will warn you if your computer’s software is out of date or not secure enough for a secure connection attempt with a website using security protocols like HTTPS/SSL/TLS.
• Incomplete Certificate Configuration: An incomplete config on the hosting server may lead to SSL cert info or auth errors, eg. missing intermediate certs or wrong Common Name fields.
• Expired Certificates: If an SSL cert expires after installation, clients will receive failed HTTPS attempts till it is renewed or replaced.

Summary of SSL Certificate
