This interface outlines the certificate chain for each sub-hierarchy in a tree structure, with the Root level on the left-most side. By clicking on a particular CA certificate, the Administrator can * View certificate details * Delete certificates * Export certificates
Users can easily filter for matching CA names using the "Search" field above the CA hierarchy. Users can delete CA certificates by clicking "Delete" in the detail view, followed by a confirmation dialog.
To finalize the deletion, please click on the "Delete" button and confirm your action. User will be prompted to authenticate the delete action. Authenticate using your Administrator token and proceed by pressing Authenticate. {% hint style="info" %} Warning : * Deleting CA certificates is highly discouraged! * CA certificates – even if expired – can be used to validate signatures later on. * Deleting CA certificates will render underlying CA certificates inaccessible as well. {% endhint %} Clicking the Export button on the right side of the detail view allows the user to export the CA certificate. * DER-encoded X.509 certificate (.cer) * Base64-encoded X.509 certificate (.cer) * Cryptographic Message Syntax Standard PKCS#7 certificate (.p7b) --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://emca.emudhra.com/previous-release-versions/v4.2.3/user-manual/administrator/view-hierachy.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. 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.
