I'm reading https://www.kaihag.com/https-and-go/ and bought an SSL certificate from Comodo which they emailed me a .zip
file. All of the files I have so far look like this
csr.pem
private-key.pem
website.com.crt
website.com.ca-bundle
website.com.zip
The above website wants me to concatenate 3 .pem
files which I don't have. Incidentally what is the reason the .pem
files need to concatenated? Using the above files which haven't been modified, how can https be set up on a golang webserver?
