Setup an Comodo positive SSL cert on AWS Cloudfront

1. Buy Comodo positive SSL cert via namecheap

2. Inspect last years cert:

   openssl req -noout -text -in tylercipriani_com.csr

3. Generate private key and signing request

• You can generate a new key as a separate step, or as part of the req command

• To generate a new key manually use:

  openssl genrsa -out /path/to/output.key 2048
  mkdir -p ~/Projects/Certs/com.tylercipriani/2015-11-24
  cd ~/Projects/Certs/com.tylercipriani/2015-11-24

• To generate a new key as part of a signing reuest use:

  openssl req -sha256 -new -newkey rsa:2048 -nodes -keyout /path/to/output.key -out /path/to/output.csr
       ensures output key is not encrypted ────┘

• Answer lots of questions

  Country Name (2 letter code) [XX]:US
  State or Province Name (full name) []:Colorado
  Locality Name (eg, city) [Default City]:Longmont
  Organization Name (eg, company) [Default Company Ltd]:Tyler Cipriani
  Organizational Unit Name (eg, section) []:.
  Common Name (eg, your name or your server's hostname) []:tylercipriani.com
  Email Address []:spam@tylercipriani.com
  A challenge password []:

  • What is a challenge password: https://tools.ietf.org/html/rfc2985#page-16

3. Should now have a tylercipriani_com.csr and an tylercipriani_com.key
4. Do the namecheap needful:
   • Login to namecheap and activate your certificate
   • xsel -p < tylercipriani_com.csr then paste in the “Enter CSR” field
   • Choose, “Apache, Nginx, or Other” as the server type
   • Verify the domain, click “Next”
   • Verify CSR info, click “Next”
   • Select “Email-based” Domain Control Validation (DCV) method
   • Company contacts page, “NA” as company name, my address in address, tyler@tylercipriani.com in admin email
5. You’ll get an email that asks you to enter a validation into a Comodo site, do that
6. You’ll get an email with tylercipriani_com.zip
7. aws configure to ensure that your awscli is setup

8. Use awscli to upload

   awscli iam upload-server-certificate \
     --server-certificate-name tylercipriani_com_2015-11-24 \
     --certificate-body file://tylercipriani_com.crt \
     --private-key file://tylercipriani_com.key \
     --certificate-chain file://tylercipriani_com.ca-bundle \
     --path /cloudfront/

9. Login to your aws dashboard, click cloudfront, go do Distribution Settings, click edit, find the new ssl key name in the dropdown and click, “Yes, edit”

10. Should work…
