Minimum SSL version enabled

Warning: Support for suppressing the TLS 1.0/1.1 warning will be removed from Google Chrome starting in version 91 (around May 2021) and this policy will stop working then.

Setting the policy to a valid value means Google Chrome won't use SSL/TLS versions less than the specified version. Unrecognized values are ignored.

If this policy is not set, then Google Chrome will show an error for TLS 1.0 and TLS 1.1, but the user will be able to bypass it.

Example value: tls1

Supported on: At least Microsoft Windows 7 or Windows Server 2008 family
