##### SUMMARY
The file contents that end up as the output of ecs_certificates "full_chain_path" are not a valid format for import into, for example, a PKCS12 store.

This is the result of the return value of the ECS API being an array, and not properly turning that array into concatenated certificates for the resulting PEM file.
