A tampered clientca.pem file could contain a malicious CA certificate. An attacker could then issue fake client certificates and impersonate legitimate users, gaining unauthorized access to your servers.
Place clientca.pem in the same folder as your .ovpn config. The config should reference: clientca.pem download
ca clientca.pem
cert client.crt
key client.key
Do not use search engines. Instead, use a bookmarked internal URL such as: A tampered clientca
Sometimes you need .crt or .cer. You can safely convert: Do not use search engines
openssl x509 -in clientca.pem -out clientca.crt
