AWSからのメール: Preparing for Certificate Transparency with AWS Certificate Manager (ACM)


Starting April 30, 2018, Google Chrome will require all publicly trusted certificates to be logged in at least two Certificate Transparency (CT) logs ( ). Any certificate issued after that date, that is not logged, will produce an error message in the Google Chrome browser. In order to comply with this requirement, as of April 24, 2018 all new and renewed AWS Certificate Manager (ACM) certificates will be logged to comply with this requirement, unless you ask us to disable CT logging.
