Users can perform a variety of actions related to CA certificates through the "Manage CA Certificate" feature in the Officer module. These actions include enrolling, revoking, suspending, reinstating, searching, signing certificate signing requests (CSR), importing PKCS12, and manually authorizing DVCA certificates.
An officer can enroll new CAs through the following UIs. The enrollment process involves generating a new CA key and a new CA certificate/CSR using that key.
Click on "Search" to open the following filter pop-up:
You can filter for Alias Name or Key Profile with equal- or contains-comparator. Click on "Search" to apply the chosen filter.
Click "Reset" to remove the filter again.
Click "Export to Excel" to export the entire table to an XLSX file. The file will be downloaded to the standard download location of your OS.
Generate Key Pair
Click on "Generate Key Pair " to open the following dialog:
Enter the number of keys that you want to generate. In general, you will need 1 key for 1 CA and 1 more key, if that CA will receive an OCSP certificate.
Select the "Key Profile" you want to use from the first dropdown list.
Choose the "Algorithm" from the drop-down
Select the "Signature algorithm" from the third dropdown list. This will filter the element for the third dropdown list accordingly.
Select the "Key Algorithm" and "Key Size" from the fourth dropdown list.
Press "Proceed" to continue and authenticate the action with your Officer token.
Click on "Generate Key Pair(s)" to generate the keys. After the successful generation of the key pair, the success message as shown below.
Click on "View all" to return to the first UI or click "+ New" to continue with this UI.
Generate CA Certificate
After creating a key pair, the user needs to select the "Generate Certificate" or "CSR" option available in the "Action" column of the created key pair.
The above image shows the default UI that will open after starting the process. There are two different options available for generation:
Certificate – use the key to generate a new CA certificate directly.
CSR – use the key to generate a Certificate Signing Request (CSR).
Choose "Certificate" if you want to directly generate a new CA certificate. This option is applicable if the CA is "self-signed", or the "issuing CA" is in the same instance
Choose "CSR" if the issuing CA is not on the same instance. This is the case if ROOT and SUB CAs are not operated on the same system.
For "Certificate", choose the Certificate type as X509, the certificate Profile you want to use for the CA certificate from the dropdown list:
Click on "View" next to the chosen certificate profile details to inspect the profile in a read-only view.
For "Subject DN Details", enter all Subject Distinguished Name (Subject DN) information for the CA. Required fields are marked with *.
Press "Proceed" to continue. You will be prompted to authenticate the action using your officer token. Press "Authenticate" to proceed.
Click on "Create" to generate the CA certificate.
The "Certificate" will be created and the user is able to download the certificate.
Generate CSR
For CSR, the following dialog will be shown:
Users can select between two certificate types: X509 and CV certificate, using radio buttons.
Select the DN attribute type from the first dropdown and add it to Subject DN.
The following "DN attributes" are available:
Select the type of SAN attribute from the dropdown list.
Press "Proceed" to continue. You will need to authenticate the action using your Officer token and then press Authenticate.
Click on Create to generate the CSR.
Upon completion, the following view will be displayed:
Click "Download CSR" to download the CSR.
An Officer can manage the CA certificates in his/her own group using the following UI.
Search
Click on Search to open the following filter pop-up:
To filter your search results, you can use either the Serial Number or the Common Name with the "equal-to" or "contains" comparator. Once you've chosen your filter, click on "Search" to apply it. If you want to remove the filter, simply click "Reset". To import an External CA certificate into the emCA Application, click on "Import Issuer Certificate". Please note that only the CA certificate will be imported, not the CA key. If you want to export the entire table to an XLSX file, click on "Export to Excel". The file will be automatically downloaded to the standard download location of your operating system.
Download LDIF
LDIF files are specially formatted text files that are used to exchange data between LDAP directory servers. If you don't intend to publish CA certificate to an LDAP system, you may not need LDIF files.
Once the download is complete, the LDIF file will be saved to the standard download location on your operating system.
