ssl - read content of base64 encoded certificate

Question

I am having some troubles reading a base64 encoded SSL certificate. What I have is a base64 encoded string without "----BEGIN CERTIFICATE----" and "----END CERTIFICATE----". I am trying to read it with multiple ways but it failed to me

I tried to read the cert via cmd

openssl x509 -in cdg_cert -text -noout 

and getting :PEM routines:CRYPTO_internal:no start Expecting: TRUSTED CERTIFICATE error

I also tried to decode the string and save it on my disk which ends up with a binary file and still couldn't read it via openssl cmd which ends up with same error

Googling around and haven't found any good hints, can anyone please help me on the cmd I should use? I am running a macbook and trying to read the cert content
