How to Find Certificate Common Name and Organization
In today’s digital age, certificates play a crucial role in ensuring the security and authenticity of various online transactions and communications. One of the key pieces of information that can be found in a certificate is the Common Name (CN) and the Organization (O). These details are vital for verifying the identity of the entity that holds the certificate. In this article, we will guide you through the process of finding the Common Name and Organization in a certificate.
Understanding the Common Name and Organization
The Common Name (CN) is a field within a digital certificate that identifies the entity or domain to which the certificate is issued. It is often used to verify the identity of the website or service when establishing a secure connection. For example, if you visit “www.example.com,” the Common Name of the certificate should match “www.example.com.”
On the other hand, the Organization (O) field represents the legal entity that issued the certificate. This could be a company, organization, or even an individual. It is essential for identifying the source of the certificate and ensuring that it is trusted.
