SSL certificates need no introduction, even to less tech-savvy users. With all of the web using them to encrypt sensitive data online, they’ve become a familiar term to website owners and visitors alike. However, not all SSL certs are identical. Besides supporting various validation levels, they have different encryption technology for specific needs.
Have you ever wondered, “What is an ECC certificate?” This article explores ECC certificates, breaking down the technical jargon into simple terms so you can easily understand their importance and how they can enhance your online security. But first, let’s see what kind of cryptography is behind ECC SSL Certificates.

What Is Elliptic-Curve Cryptography?
Elliptic curve cryptography (ECC) is a form of public-key cryptography based on the mathematical structure of elliptic curves over finite fields. Unlike the traditional RSA algorithm, which relies on the difficulty of factoring large integers, ECC uses the properties of elliptic curves to create secure cryptographic keys.
Think of an elliptic curve as a particular curve on a graph. It has a unique, smooth, and symmetrical shape that resembles a gently sloping hill or an elongated loop. A specific mathematical equation defines this curve. The beauty of elliptic curves lies in their complex structure, which makes them very useful for creating secure cryptographic systems.
A finite field is a set of numbers that contains a limited, or “finite,” number of elements. In this set, you can perform addition, subtraction, multiplication, and division operations while still staying within the set. Imagine a clock where numbers wrap around after reaching a specific value (like 12 going back to 1). This concept of wrapping around is similar to how numbers behave in finite fields.
ECC uses the intricate and hard-to-predict patterns of elliptic curves combined with the constrained and controlled environment of finite fields to create cryptographic solid keys that are difficult for attackers to break.
How Does Elliptic Curve Cryptography Work?
The ECC algorithm takes advantage of the complex mathematics behind elliptic curves. Here’s how it works on the surface without touching the intricate technical details and equations.
- Key Generation: ECC generates keys through the properties of the elliptic curve. It involves selecting a random elliptic curve point and performing operations to create a public key and a private key. The private key is kept secret, while the public key is shared.
- Encryption and Decryption: When a client wants to send encrypted data to a server, it uses the server’s public key to encrypt the data. Only the server’s private key can decrypt this data, ensuring a secure connection.
- Digital Signatures: ECC is also used to create digital signatures, which verify the authenticity and integrity of messages or data. This involves creating a message hash and using the private key to sign it. Anyone can verify the signature using the corresponding public key.
Advantages and Disadvantages of Elliptic Curve Cryptography
ECC in cybersecurity offers several advantages, but it also comes with its challenges. Let’s first see its benefits and then the drawbacks:
Advantages of Elliptic Curve Cryptography
- Smaller Key Size: One significant advantage of ECC is that it provides strong security with smaller key sizes compared to RSA certificates. For instance, a 256-bit ECC key offers comparable security to a 3072-bit RSA key.
- Performance: Smaller keys mean faster computations, leading to better network performance and quicker secure connections for mobile devices and low-power systems.
- Security: ECC is considered more secure because the discrete logarithm problem it is based on is more complex to solve than the factoring significant integers problem RSA uses.
Disadvantages of Elliptic Curve Cryptography
- Complexity: ECC is more complex to implement and requires careful configuration to ensure security. Incorrectly configured systems may not provide the expected level of protection.
- Compatibility: Not all systems and applications support ECC, though this is becoming less of an issue as more platforms adopt it.
What Is an ECC Certificate in Cyber Security?
An ECC certificate is a digital certificate that uses elliptic curve cryptography to provide secure communication over the Internet. These certificates establish a secure connection between a client and a web server, ensuring that data transmitted between them is encrypted and protected from eavesdropping or tampering.
ECC certificates work similarly to traditional SSL certificates but use the Elliptic Curve Cryptography algorithm algorithm instead of the RSA algorithm. They are increasingly popular because they offer robust security with better performance.
ECC certificates are precious in environments where resources are limited, such as mobile devices and IoT gadgets. They ensure that data transmitted between parties remains confidential and tamper-proof, which is crucial in today’s digital landscape.
How to Get an ECC Certificate?
Sectigo (formerly Comodo) and DigiCert are reliable Certificate Authorities offering ECC certificates. When ordering one of their certs, indicate the preferred algorithm, RSA or ECC, and make sure your web server supports it.
No matter the website type, Sectigo provides the cheapest ECC SSL certificates on the market, while DigiCert offers premium high-assurance level certs for businesses and enterprises.
After you buy the certificate from SSL Dragon, here’s a breakdown of your next steps:
- Generate a Certificate Signing Request (CSR): The first step is to generate an ECC certificate signing request. This CSR contains information about your domain and public key.
- Submit to a CA: Submit the CSR to a trusted CA, which will verify your information and issue an ECC certificate.
- Install the Certificate: Once issued, you must install the ECC SSL certificate on your web server. This process varies depending on your server software but generally involves uploading the certificate files and configuring your server to use them.
Bottom Line
ECC certificates are a big step forward in digital security. They offer strong encryption with smaller key sizes, making secure connections faster and more efficient. Though they can be tricky to set up, the security and performance benefits are worth it for any user and organization wanting better online protection.
Now that we’ve answered the “What is an EEC certificate question?“, you can make wise choices about your digital security. Knowing about advancements like ECC certificates is critical to keeping systems secure and efficient as technology evolves. Whether you’re a small business or a large enterprise, ECC certificates provide a future-proof way to protect your data.
