The merchant generates a secret key and a CSR (Certificate Signing Request). In a CSR, the Organizational Unit Name (OU) field of the Subject element must be entered with the value "M{MerchantId}". The MerchantId value must consist of 15 characters M000...00<Merchant_ID>, where Merchant_ID is the number of the merchant registered in IPS Assist. The keyUsage element must specify the purpose of the "digitalSignature" key. To download the certificate request, click the "Download Upload CSR" button. Next, a standard browser window will open for selecting a CSR file.
After loading the request, a certificate line is created in the table with the status "Active" and its validity period. Above the table is a link to a pre-made JSON Web Key Set (JWKS) with this certificate. The certificate can also be downloaded separately, using the context menu (Get certificate).
