Are certificates really safe?
Thanks for the plain English explanation.

Understanding that certificates supposedly confirm that a given site is the actual site the issues surrounding them are:

1. they can be spoofed. For example Google changes its certificates every week after someone spoofed theirs.

2. they provide huge amounts of metadata to the certifying agent. For example, to reach a website a client must first clear the connection through a third party. that third party can collect data from the client, computer, OS, IP, cookies, and a host of data. As such it offers bad agents an opportunity to sell that data. Google and Cloudflair are two who have that data and compile it. In other terms Certificates may confirm a site is a site but at what cost?

3. If the purpose of a certificate is to encrypt a communications channel, why can't a site simply issue its own one time use encryption? Could it be that Google can't collect data if clients don't go through Google so they make it a requirement?

 

In general the idea of a 'certificate' issued by a third party is simply a bandaid that makes Google and others wealthy rather than encouraging better ideas to provide security, identity and more privacy.
