Creating an SSL Certificate for Azure App Services

  1. Generate the CSR (Certificate Signing Request).  An easy way to do that is
  2. Take the output of this page and run it in a Bash shell, or some place that you have access to the OpenSSL library.  This will create a csr file and a key file. 
  3. Buy the certificate.   These guys have good prices:
  4. As part of the checkout, it will ask you to type in the text of the CSR file generated by OpenSSL in Step 2 above. 
  5. Not sure what to select when asked for Apache vs Windows.  But selected Windows, and I got a .cer file.  Support had to send me a .crt file instead. 
  6. After verifying who you are, then will send you a .crt file. 
  7. Use OpenSSL again to convert the .crt file and the .key file to a pfk
    openssl pkcs12 -export -out myserver.pfx -inkey myserver.key -in myserver.crt
  8. Upload the resulting .pfx file to the server.
