Office 365 are retiring 3DES

(1/1)

Simon Kemp:
Hi all,

"Office 365 will retire 3DES starting February 28, 2019."

I know nothing about ciphers! Sounds frightening - will this effect us sending emails using TLS 1.2? NetTalk 9.18

Thanks,
Simon

Bruce:
Hi Simon,

Not it won't affect it. (He said confidently).
3DES is a _cipher_ (one of many possible ciphers used by TLS).
You're on a very old nettalk, so you _may_ need to change the CipherList yourself, but even that would be "unlikely".

(I change the default cipherlist from time to time, in accordance with current best practices, so you are on an old one - but you can set it your self. See http://www.capesoft.com/docs/NetTalk11/NetTalkWebSecure.htm#Ciphers


Cheers
Bruce

Simon Kemp:
Thanks Bruce.
