TT will no longer provide or update the stunnel.zip file which customers had previously used to perform certificate pinning.
Clients who previously download the stunnel.zip file from https://library.tradingtechnologies.com/tt-fix/general/stunnel.zip should migrate to their local machine’s certificate trust store as soon as possible. Digicert and AWS are both established Certificate Authorities and are available in the trust stores of modern operating systems.
Migration & Rollout Schedule:
1. September 22 (UAT): AWS trust store support is enabled in UAT. Clients connecting to UAT must AWS is trusted within their certificate store.
2. September 23 -24 (Prod Sim): AWS trust store support is enabled in prod-sim. Clients connecting to prod-sim must ensure AWS is trusted within their certificate store.
3. September 25 (Production): AWS trust store support is enabled in production New York data centers. Clients connecting to production must ensure AWS is trusted within their certificate store.
4, October 2 (Production): Production deployment to begin in Aurora, Chicago, Sao Paulo, London, Basildon, Frankfurt data centers
5. October 9 (Production): Production deployment to begin in all other remaining data centers
Upon the deployment of the change to each environment, the Digicert certificate will be replaced with an AWS certificate, which is not included in the stunnel.zip. All impacted clients must add AWS to the local trust store.
