Every reputable online business needs to have a valid SSL certificate to safeguard their clients’ security and brand’s credibility. SSL certificate errors on your site can severely damage your brand reputation, push visitors away, and affect your SEO ranking. In this post, we’ll focus on what an SSL certificate is, common SSL errors, and how to fix them.
An SSL certificate is a digital certificate that authenticates a website’s identity and allows an encrypted connection. SSL (Secure Socket Layer) and TLS (Transport Layer Security) are encryption protocols that provide security for online transactions and sensitive information.
When you access a website over HTTPS, your browser connects to the server and requests verification of the site’s identity. The server sends its SSL certificate and public key to the browser. After verifying the certificate, both entities compute a new symmetric encryption key, and a secure connection is established using this key to encrypt the data in transit. This process is known as the SSL handshake.
An SSL certificate is vital for any website, as it secures sensitive information by encryption, verifies the website’s identity, and improves its SEO ranking. For retailers accepting online payments, an SSL certificate is required for PCI compliance. Additionally, having an SSL certificate provides a better user experience and instills trust in your brand.
Common SSL errors include Let’s Encrypt installation errors, expired SSL certificate error, SSL certificate not trusted error, name mismatch error, mixed content error, and generic SSL protocol error.

What Is an SSL/TLS Certificate?
An SSL/TLS certificate is a vital component in ensuring the security of online transactions and safeguarding sensitive information. It acts as a digital certificate that guarantees the authenticity of a website’s identity and facilitates a secure and encrypted connection between the user’s browser and the web server.
The acronym SSL stands for Secure Socket Layer, while TLS stands for Transport Layer Security. Both SSL and TLS are encryption protocols that establish a secure communication channel by encrypting data and verifying the integrity of the connection.
An SSL/TLS certificate serves as a digital passport that enables secure communication by utilizing encryption algorithms. This certificate is issued by a trusted Certificate Authority (CA) and contains crucial information such as the website’s domain name, public key, and other identifying details.
“An SSL/TLS certificate acts as a digital certificate that guarantees the authenticity of a website’s identity and facilitates a secure and encrypted connection.”
While SSL is a more widely recognized term, all SSL certificates are based on the TLS protocol. The TLS protocol has undergone several iterations, with newer versions providing enhanced security features and improved encryption algorithms. However, for simplicity, the term SSL is used interchangeably to refer to TLS certificates.
By implementing an SSL/TLS certificate on a website, businesses can establish trust with their users and create a secure environment for sensitive transactions, including online payments, personal data submission, and confidential interactions.
| Key Components of an SSL/TLS Certificate | Explanation |
|---|---|
| Domain Name | The domain name of the website for which the SSL/TLS certificate is issued. |
| Public Key | A cryptographic key that is used for encrypting data during SSL/TLS communication. |
| Issuing Authority | The trusted Certificate Authority (CA) responsible for issuing the SSL/TLS certificate. |
| Validity Period | The duration for which the SSL/TLS certificate remains valid before it needs to be renewed. |
| Digital Signature | A unique cryptographic signature that verifies the authenticity and integrity of the SSL/TLS certificate. |
How SSL Certificates Work
When you access a website over HTTPS, your browser connects to the server and requests verification of the site’s identity. The server sends its SSL certificate and public key to the browser. After verifying the certificate, both entities compute a new symmetric encryption key, and a secure connection is established using this key to encrypt the data in transit. This process is known as the SSL handshake.
During the SSL handshake, the browser and server exchange critical information to establish a secure connection. Let’s break down the key steps:
- Browser Request: When you type in a website’s URL starting with “https://,” your browser initiates a secure connection request to the server.
- Verification: The server responds by sending its SSL certificate, which contains its public key for encryption.
- Certificate Validation: Your browser verifies the certificate’s authenticity and checks if it’s issued by a trusted Certificate Authority (CA). This step ensures that the website you’re visiting is legitimate and not an imposter.
- Key Agreement: If the certificate is valid, both the browser and server generate a new symmetric encryption key. This key will be used to encrypt and decrypt data during the secure session.
- Secure Connection Establishment: With the encryption key established, a secure connection is established between your browser and the server. This ensures that any data transmitted between the two parties is encrypted and protected from potential eavesdropping or tampering.
This secure connection allows you to transmit sensitive information, such as passwords, credit card details, or personal data, without the risk of interception. SSL certificates play a crucial role in building trust between websites and their visitors, ensuring a safe online experience.
Benefits of SSL Certificates
Using SSL certificates provides several benefits:
- Data Encryption: SSL certificates encrypt the data transmitted between the browser and the server, making it unreadable to unauthorized parties.
- Website Authenticity: SSL certificates verify the identity of the website, assuring visitors that they are connecting to the intended site and not a malicious imposter.
- SEO Ranking: Search engines prioritize websites with SSL certificates, improving their visibility and rankings in search results.
- Trust and Credibility: SSL certificates instill confidence in visitors, reassuring them that their information is secure and protected.
- PCI Compliance: For e-commerce businesses handling online payments, SSL certificates are a requirement to meet Payment Card Industry Data Security Standard (PCI DSS) compliance.
By understanding how SSL certificates work and the benefits they provide, you can ensure the security of your website and gain the trust of your visitors. Stay informed about SSL best practices and ensure your SSL certificate is up to date to maintain a secure and reliable online presence.
Why You Need an SSL Certificate
An SSL certificate is vital for any website as it secures sensitive information by encryption, verifies the website’s identity, and improves its SEO ranking. With cyber threats on the rise, website security is of utmost importance. An SSL certificate ensures that data transmitted between a user’s browser and your website is encrypted, making it nearly impossible for hackers to intercept and decipher the information.
Additionally, an SSL certificate establishes trust with your website visitors. When users see the padlock icon or “https” in the URL, they know that their connection to your site is secure, and they can trust that their personal information is protected.
Having an SSL certificate also has a direct impact on your SEO ranking. Search engines prioritize secure websites in their search results, meaning that having an SSL certificate can boost your website’s visibility and organic traffic.
For retailers accepting online payments, an SSL certificate is a requirement for PCI compliance. Payment Card Industry Data Security Standard (PCI DSS) ensures that businesses handling credit card information maintain a secure environment to protect cardholder data and prevent data breaches.
Moreover, an SSL certificate enhances the user experience. Websites without SSL certificates often display warning messages to users, alerting them of potential security risks. These warnings can deter visitors from accessing your site and lead to a high bounce rate, negatively impacting your website’s credibility and conversion rates.
Overall, investing in an SSL certificate is essential to protect your website and user data, establish trust with your audience, improve your search engine rankings, comply with industry standards, and deliver a seamless user experience.
