There is an iredmai mail server on centOS. His ssl certificate has expired. How to regenerate another certificate? Root certificate sca.server1.crt

Answer 1

Issue it again in the CA where you received it. If self-signed or released by a corporate CA, re-release.
You can convert the certificate into a readable form with the command:
or if you want to save it in a file:

# openssl x509 -in файл_сертификата -out файл_текстовый -text
