This might be me having done it wrong. I recently used OpenSSL to convert a .cer to .pem using this -
openssl x509 -inform der -in certificate.cer -out certificate.pem
(And then loaded the .pem onto the loadbalancer)
However the client browser (chrome) reports it's SHA-1 and although it works, (connectivity wise) it doesn't look good. Plus SHA-1 is old/being phased out.
Is this because of the openssl command I used? Should I have used -sha256 in my openssl command (from a quick googling around)
As you can tell, bit new to certificates!
