Reproduce the error

To reproduce in base ruby and AWS connections on Windows, run irb:

require open-uri
open https://s3.amazonaws.com

You will see a similar stack trace to http://stackoverflow.com/questions/9199660/why-is-ruby-unable-to-verify-an-ssl-certificate.

Newer versions of Amazon SDKs include ca-bundle.crt from https://curl.haxx.se/docs/caextract.html.

Partial Solution

  1. Download the bundled version from https://github.com/aws/aws-sdk-ruby/blob/master/aws-sdk-core/ca-bundle.crt
  2. Add a Windows system variable named SSL_CERT_FILE, and the value should be the path - C:\....\ca-bundle.crt.

Trouble on the Stripe front

I could open https://api.stripe.com/v1 just fine, but for some reason I started getting these same SSL verify thangs from Stripe when using their gem. Turns out they bundle … https://github.com/stripe/stripe-ruby/blob/master/lib/data/ca-certificates.crt

What worked for me was dropping into Cygwin and overwriting the Stripe bundle with the ca-certificates package bundle:

cp /etc/ssl/certs/ca-bundle.crt /cygdrive/c/Ruby21-x64/lib/ruby/gems/2.1.0/gems/stripe-1.35.1/lib/data/ca-certificates.crt
