I\'m having trouble. I followed a guide that I found here
http://www.thenetworkadministrator.net/index.php/2011/12/iis-ssl-certificate-into-amazon-elastic-load-balancer/
Simplest/most concise explanation that I have come across for creating a self-signed cert for AWS ELBs is...
openssl genrsa -out server_privatekey.pem 1024
openssl req -new -key server_privatekey.pem -out server_certificate_csr.pem
openssl x509 -req -days 3650 -in server_certificate_csr.pem -signkey server_privatekey.pem -out server_certificate.pem
And then in AWS;
Certificate Name: mycert
Private key: [content of server_privatekey.pem]
Public key: [content of server_certificate.pem]
Certificate Chain: [content of server_certificate_csr.pem]
