TLS 1.2 minimum protocol

[davidlfox]

Per the AWS changes coming in June, how can I tell the oldest version of this SDK that supports TLS 1.2?

My app is using '~> 1.96', '>= 1.96.1'

I don't currently have any of the AWS-side logs configured (e.g. CloudWatch, etc) to determine from the server side. How can I confirm this from the client side?

See: https://docs.aws.amazon.com/sdk-for-ruby/v3/developer-guide/tls-version.html - basically, the version of openssl used determines the TLS 1.2 support. You need OpenSSL 1.0.1 or higher - you can check with:

ruby -r openssl -e 'puts OpenSSL::OPENSSL_VERSION'
