To maintain the integrity of the SSL certificate chain, it’s crucial to complete the chain of trust with a CA bundle that includes the intermediate and root certificates. If you’ve purchased a PrimeSSL certificate with RSA key encryption and domain validation, the intermediate certificate is necessary so your certificate chains correctly to the Sectigo Public Server Authentication Root E46.
Download or copy the intermediate certificate from the PrimeSSL CA bundle. It is powered by Sectigo’s Public Server Authentication Root E46, featuring RSA encryption and domain validation.
Simply copy and paste the full certificate, including the —–BEGIN CERTIFICATE—– and —–END CERTIFICATE—– lines, into a text editor and save the file to your server.
