Gmail to Discontinue Support for 3DES in Incoming SMTP Connections

By Netvora Tech News

Google has announced that it will discontinue support for the Triple Data Encryption Standard (3DES) in incoming SMTP connections, effective three weeks from now. Starting May 30, mail servers that use 3DES for SMTP connections will no longer be able to deliver emails to Gmail accounts. The move is necessary to improve security and protect users against potential vulnerabilities associated with the outdated encryption standard. Google emphasizes that a secure TLS connection allows for various encryption algorithms to be chosen from, with 3DES being one of them. In 2017, the National Institute of Standards and Technology (NIST) advised against using 3DES in new applications, and by 2023, it is expected to be completely phased out. Google urges system administrators to verify that their mail servers are configured to use more modern encryption algorithms. In cases where domains report sending emails to Gmail accounts using 3DES, Google says it will send an additional email with more information to system administrators. The tech giant advises administrators to take immediate action to ensure the security of their email systems.

Why is 3DES becoming obsolete?

3DES, also known as Triple DES, is an encryption algorithm that was widely used in the past to encrypt data. However, it has been deemed insecure due to its slow processing speed and the possibility of brute-force attacks. Modern encryption algorithms, such as AES, are faster and more secure, making them a better choice for encrypting data.

What does this mean for Gmail users?

Gmail users should not experience any disruptions in their email services as a result of this change. However, system administrators who manage mail servers should take immediate action to ensure that their servers are configured to use more modern encryption algorithms.

Google's decision to discontinue support for 3DES is a step towards improving the security of Gmail accounts and protecting users against potential vulnerabilities. As the tech giant continues to prioritize security, it is essential for system administrators to stay up-to-date with the latest encryption standards and guidelines.
