Background of the problem

As you know, to check the reliability and security of sites in the Internet uses special “security certificates”. Such certificates are issued by specially authorized centers. certification, certifying the security of working with a network resource, received such a certificate.

The certificate store of your browser (or OS) is stored root certificates that tell the system (browser) which you can safely go to the site and use it safely functionality.

Moreover, far from always authorized certification centers work legally and correctly. Repeated abuse of unverified issuance of certificates, retroactive issuance of certificates and so on. To combat this Google has created a special project – Certificate Transparency (translated as “Certificate Transparency”), which keeps a log (log) of issued certificates, allowing everyone wishing to track the legality of issuing a certificate, transparency conditions for its issuance, certificate holder, and so on. This and causes an error message net :: ERR_CERTIFICATE_TRANSPARENCY_REQUIRED.

When you try to load a page in a browser, you may also experience errors with textSEC_ERROR_REVOKED_CERTIFICATE andERR_CERT_AUTHORITY_INVALID.

Some browsers (particularly those based on Chromium) reject Certificates that are not included in the “Certificate Transparency” log. IN October 2016 Google accuses Symantec of largest certification authority in the use of unconfirmed “test” certificates for google.com and other 75 domains. Google announced that it will require confirmation from Sertificate Transparency “for all certificates issued by” Symantec “after 1 June 2016, including Symantec brands such as Thawte and “GeoTrust”. This complaint was embodied in the published Google Chrome version 53 rejecting Symantec certificates “as unverified.
