For troubleshooting purposes, you can open a custom certificate file in a text editor and inspect its contents.

PEM Format Certificate Files

A typical PEM format certificate file resembles the following sample.

-----BEGIN CERTIFICATE-----

Private Keys

Private keys can appear in different formats but are enclosed with clear BEGIN and END markers.

Valid PEM sections begin with one of the following markers.

-----BEGIN RSA PRIVATE KEY----- 
-----BEGIN PRIVATE KEY-----

Encrypted private keys begin with the following marker.

-----BEGIN ENCRYPTED PRIVATE KEY-----

Bag Attributes

Microsoft certificate tools sometimes add Bag Attributes sections to certificate files. VMware Aria Operations safely ignores content outside of BEGIN and END markers, including Bag Attributes sections.
