| If this policy is not configured then Google Chrome uses a default minimum version, which is TLS 1.0. Otherwise, it may be set to one of the following values: "tls1", "tls1.1" or "tls1.2". When set, Google Chrome will not use SSL/TLS versions less than the specified version. An unrecognized value will be ignored. "tls1" = TLS 1.0 "tls1.1" = TLS 1.1 "tls1.2" = TLS 1.2 |
