Google announced it is stopping support for SSLv3 and RC4 encryption after 16 June 2016. This affects all Google SMTP servers and Gmail web servers.
Users using these services, such as webmasters running applications from the Google Apps platform and those using Gmail, should adjust their services to avoid technically problems and downtimes.
Επιπλέον, οι χρήστες που χρησιμοποιούν παλαιότερους clients ηλεκτρονικού ταχυδρομείου και υπηρεσιών Web που κάνουν Mission messages via SSLv3 and RC4 will no longer be able to exchange e-mail messages with Google's infrastructure.
“SSLv3 has been out of date for over 16 years and is so full of known problems that the Task Force Internet Engineering (IETF) has decided that it should no longer be used,” Google engineers explained.
"RC4 is a 28-year-old encryption that was impressively good, but now it's the subject of multiple attacks at security conferences. The IETF has decided that RC4 should not and will not be used anymore. "
While everyone already knew that RC4 was weak encryption, SSLv3 was still considered acceptable until 2014, when with attack POODLE proved otherwise. Some implementations of TLS are also vulnerable.
Google initially announced that he would abandon SSLv3 and RC4 last autumn, but did not give any time.
