How to check if you're TLS 1.2 compliant

On August 1, 2022 we are ending support for TLS 1.0 and 1.1. This may have an impact on your use of the MessageMedia REST and/or SOAP API if the systems you have in place do not support TLS 1.2 or higher.

Here's the endpoint which you can use to verify that your systems are TLS 1.2 compliant:

https://test-tls12.messagemedia.com

• It accepts all methods (GET, POST, PATCH, etc) and doesn’t require any credentials.
• If it is successful the endpoint will return Connected successfully with TLS 1.2
• If it is unsuccessful an error message will be returned such as OpenSSL SSL_connect: SSL_ERROR_SYSCALL

Process for Linux Users

Here are the steps to test your TLS 1.2 compliance using CURL command on a Linux machine:

1. Test default CURL TLS choice:

curl -k 'https://test-tls12.messagemedia.com'

• Success message from CURL if TLS 1.2 supported: Connected successfully with TLS 1.2
  Other than that, any error code likely indicates a failure.

2. Test CURL with force TLS 1.2:

curl -k --tlsv1.2 --tls-max 1.2 'https://test-tls12.messagemedia.com'

• Same success message expected.

3. If failure is consistent (except for a connection error which is probably a VPN or firewall issue), that indicates no support for TLS 1.2, for the CURL version on that particular machine.
