Upcoming Policy Changes
One of the major focal points of Version 1.5 requires that applicants seeking inclusion in the Chrome Root Store must support automated certificate issuance and management. […] It’s important to note that these new requirements do not prohibit Chrome Root Store applicants from supporting “non-automated” methods of certificate issuance and renewal, nor require website operators to only rely on the automated solution(s) for certificate issuance and renewal. The intent behind this policy update is to make automated certificate issuance an option for a CA owner’s customers.
Hi I’m 5 years old and I have no clue what you just said.
In order to know that you are talking to the right website on the web, you need someone else that you trust to say they are who they say they are. That is a Certificate Authority. They verify that the example.com you are talking to is the actual example.com through math that's hard to fake. Currently, the process of performing this verification can be either done manually by a person or automatically through software depending on what the Certificate Authority supports. Chrome is planning on changing their policy to require that an automatic option be available for all Certificate Authorities, without necessarily taking away the manual option from those who still want to use it.
That was absolutely digestible by a 5 year old like me. Many thanks!
