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/
Please read the post: AWS Load Balancer SSL limitations. The following solution worked for me:
openssl rsa -in server.key -text
Then copy and paste the produced output between (including):
-----BEGIN RSA PRIVATE KEY-----
and
-----END RSA PRIVATE KEY-----
AWS Load Balancer had accepted this key successfully.
