# Key Concepts and Terminology Before you can get the most out of CERTInext, it helps to have a solid grounding in the terminology the platform uses - not just the obvious terms like "certificate" and "CA," but the operational concepts that shape how things actually work day to day. This section covers the foundational vocabulary: digital certificates, Certificate Authorities (CAs), private and public PKI, Certificate Signing Requests (CSRs), domain validation, discovery, provisioning, renewal, revocation, and automation workflows. It also walks through the operational components you'll encounter in the platform - Bots, scan targets, CA connectors, key stores, and trust chains - and explains the distinction between discovery and provisioning, which trips up a lot of new users. Getting this vocabulary straight matters because it affects how you configure integrations, read dashboard metrics, apply lifecycle controls, and troubleshoot when something goes wrong. It also gives technical, operational, and compliance teams a shared language, which is often the first thing that breaks down when certificate incidents occur. Whether you're connecting to public CAs like emSign and DigiCert, working with private CAs such as emCA or AD CS, or managing cloud and container environments, consistent terminology is what keeps policy enforcement coherent across the board. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.certinext.io/documentation/getting-started/key-concepts-and-terminology.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
