I’m following this guide:
https://www.thesslstore.com/knowledgebase/ssl-install/tomcat-ssl-installation/

Got the .p7b file from name.com, moved it into my droplet, then ran:

keytool -import -trustcacerts -alias server -file placeholder.p7b -keystore placeholder.jks

But it’s throwing:

keytool error: java.lang.Exception: Input not an X.509 certificate

I followed by running:

openssl x509 -in placeholder.p7b -text

And got:

unable to load certificate
140089256595904:error:0909006C:PEM routines:get_name:no start line:../crypto/pem/pem_lib.c:745:Expecting: TRUSTED CERTIFICATE

Does that mean my certificate is corrupted somehow? (I didn’t even touch it, just downloaded it)
