I used this code
# Generate the RSA keys and certificate
openssl req -x509 -nodes -days 365 -newkey rsa:1024 -sha1 -subj \
'/C=US/ST=CA/L=Mountain View/CN=www.example.com' -keyout \
myrsakey.pem -out /tmp/myrsacert.pem
From here: http://code.google.com/apis/gdata/docs/auth/authsub.html#Registered
Google links to this from their own ManageDomains site. I have used the code, and uploaded the pem file to Google. When I test it, it gives me this error:
SyntaxError: Missing PEM Prefix
Can anyone point me in the right direction, I've wasted several hours on this. Thanks!
