The US Department of Treasury is initiating the annual renewal of the public certificate securing www.treasury.gov website, including OFAC sanctions list downloads. The existing certificate (expiring September 9, 2021) will be replaced on September 1, 2021 at 9PM. This process will take roughly 3-6 hours for the replacement certificate to be distributed worldwide.
If your application pins or otherwise trusts the serial number of the existing certificate as part your application functionality, you may need to update your configuration to trust the renewed certificate. The renewed public certificate, effective September 1, 2021 at 9PM, can be downloaded via the following URL, https://s3.amazonaws.com/www.treasury.gov-2021-certificate/www.treasury.gov-2021-2022-Renewed-Certificate.zip. To prevent loss in functionality, please ensure your applications trust this certificate by the September 1 replacement date.
After the renewed certificate is deployed on September 1, you may view the renewed certificate publicly via these instructions.
Please contact OFAC technical support at 1-800-540-6322 Option #8 or O_F_A_C@treasury.gov with any questions that you may have about this change.”
