To set up a “secure” internet connection such as one necessary for secure banking transactions, digital ‘certificates’ are provided by companies to keep others from falsely claiming to provide what they are not able to deliver.
For instance, you wish to purchase something from a company (Sears, Lowe’s, Colt Armaments, etc.) online so that company provides a digital certificate to ensure that you are truly dealing with them and not some fraud.
The article states that Google no longer trusts the Symantec digital certificates for certain reasons, which is notable since Symantec is a “security” company themselves.
