Η Google announced that it is dropping support for SSLv3 and RC4 encryption after June 16, 2016. This affects all Google SMTP servers as well as Gmail web servers.
Users who use these services, such as webmasters running Google Apps apps and those using Gmail, need to customize their services to avoid technical problems and downtimes.
In addition, users who use oldestυς clients ηλεκτρονικού ταχυδρομείου και υπηρεσιών Web που κάνουν Mission μηνυμάτων μέσω SSLv3 και RC4 δεν θα είναι πλέον σε θέση να ανταλλάσσουν messages e-mail με τις υποδομές της Goοgle.
"SSLv3 has been out of date for over 16 years and is so riddled with known issues that the Internet Engineering Task Force (IETF) has decided that it should no longer be used," explained Google technicians.
"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 was already aware that RC4 was a weak encryption, SSLv3 was still acceptable until 2014 when the POODLE attack proved to the contrary. Some TLS applications are also vulnerable.
Google initially announced that he would abandon SSLv3 and RC4 last autumn, but did not give any time.
