SHA1 & Google Chrome Checker

Beginning in October 2014, Google Chrome will start to show warnings for many sites with SSL/TLS certificates signed with the aging SHA1 signature algorithm.

Google Chrome will slowly phase this in based on when the end-identities certificate expires (and if any certificate uses SHA1). Depending on the end-identities expiry date will depend on the severity of the warning - also - each consecutive version of Google Chrome, beginning with Google Chrome 39, will potentially make the warning more severe.

Type in a website below, that uses SSL/TLS, to check if it is affected, and if so, which warning will occur and approximately when.
