Introduction to Extended Validation SSL Certificate (EV SSL)
Extended Validation SSL Certificate (EV SSL) is a highly secure digital certificate used to establish a secure connection between a user’s web browser and a website server. It provides a robust encryption mechanism, ensuring that sensitive data transmitted between the user and the website remains confidential and protected from potential cyber threats. EV SSL is considered one of the most advanced and reliable security measures available for online businesses, particularly those handling sensitive information.
The History of Extended Validation SSL Certificate (EV SSL)
The concept of SSL certificates was introduced in the 1990s by Netscape, which aimed to secure online communications. Over time, SSL (Secure Sockets Layer) evolved into its successor, TLS (Transport Layer Security), which is the current standard for secure web connections. The first mention of EV SSL can be traced back to 2006 when the Certification Authority Browser Forum (CA/B Forum) developed the EV SSL standard.
Detailed Information about Extended Validation SSL Certificate (EV SSL)
An Extended Validation SSL Certificate undergoes a more stringent validation process compared to other types of SSL certificates. Its main purpose is to provide a higher level of trust to website visitors by displaying a green address bar with the organization’s name, prominently indicating that the website is secure and belongs to a legitimate entity.
The validation process involves verifying the legal existence of the organization, its physical address, and the right to use the domain name associated with the certificate. This verification is typically performed by a trusted third-party Certificate Authority (CA). The CA checks the applicant’s details against trusted databases and government records to ensure authenticity.
The Internal Structure of Extended Validation SSL Certificate (EV SSL)
The internal structure of an EV SSL certificate is similar to that of other SSL certificates. It consists of several fields containing information about the certificate’s owner, the CA that issued it, the validity period, and the public key used for encryption. Notably, an EV SSL certificate includes an additional field called the “Certificate Policies” extension, which explicitly indicates that the certificate adheres to the Extended Validation guidelines.
When a user accesses a website with an EV SSL certificate, their browser performs a series of checks on the certificate to ensure it meets the EV criteria. If all checks pass, the browser displays the green address bar, affirming the website’s security.
Analysis of the Key Features of Extended Validation SSL Certificate (EV SSL)
The key features of EV SSL certificates include:
-
Enhanced Trust: EV SSL offers the highest level of trust among SSL certificates, assuring users that they are interacting with a legitimate and verified entity.
-
Visible Security Indicators: The green address bar and the organization’s name displayed in the browser provide a clear visual indication of a secure connection, boosting user confidence.
-
Phishing Protection: The rigorous validation process helps prevent phishing attacks by confirming the authenticity of the website owner.
-
256-bit Encryption: EV SSL uses strong encryption algorithms to secure data during transmission, ensuring maximum protection against eavesdropping and data tampering.
Types of Extended Validation SSL Certificate (EV SSL)
There are no specific subtypes of EV SSL certificates; rather, all EV SSL certificates follow the same validation guidelines. However, EV SSL certificates can be categorized based on the number of domains or subdomains they protect:
| Type | Description |
|---|---|
| Single-Domain EV SSL | Protects a single domain and its subdomains, if specified. |
| Multi-Domain EV SSL | Secures multiple domains with different names under one cert. |
| Wildcard EV SSL | Covers all subdomains of a single domain with one certificate |
Ways to Use Extended Validation SSL Certificate (EV SSL)
EV SSL certificates find applications in various scenarios:
-
E-commerce Websites: EV SSL is essential for online stores to build customer trust during payment transactions and safeguard personal and financial data.
-
Banking and Financial Institutions: Banks and financial institutions use EV SSL to secure their online banking platforms and protect customer information.
-
Government Websites: Government websites handling sensitive citizen data utilize EV SSL to establish secure connections and prevent unauthorized access.
-
Login and Authentication Pages: Websites with login pages use EV SSL to ensure secure login credentials and prevent unauthorized access.
Problem: EV SSL certificates are generally more expensive than other types of SSL certificates.
Solution: Considering the enhanced security and trust they provide, the cost of EV SSL certificates is justified for organizations handling sensitive data.
Problem: The validation process for EV SSL certificates can be time-consuming.
Solution: While the validation process is more extensive, it is a necessary step to establish the credibility of the website and enhance user trust.

Perspectives and Future Technologies
The field of SSL certificates is continually evolving to keep pace with emerging threats and security requirements. In the future, we may see improvements in:
-
Quantum-Resistant SSL: As quantum computing becomes more prevalent, SSL certificates resistant to quantum attacks will gain importance.
-
Certificate Transparency: Wider implementation of Certificate Transparency will enhance certificate issuance and improve transparency in the SSL ecosystem.
-
Automated Validation: Automation of validation processes may reduce the time and complexity involved in obtaining EV SSL certificates.
Extended Validation SSL Certificate (EV SSL) and Proxy Servers
Proxy servers, like OneProxy, play a crucial role in enhancing online privacy and security. By acting as an intermediary between the user and the internet, proxy servers can mask the user’s IP address and encrypt data, providing an additional layer of protection.
While EV SSL certificates are primarily associated with securing websites and web applications, proxy servers can also benefit from using EV SSL certificates. Proxy providers can use EV SSL on their websites to assure users that their services are reliable and secure. Additionally, by encrypting proxy server communications using EV SSL, providers can enhance the confidentiality of user data and protect against potential cyber attacks.
