Reminder: Deprecation of Cipher Suites That Use SHA-1 for TLS Communication
We are aware that some accounts are still using a cipher suite that uses the SHA-1 algorithm for secure communication with NetSuite. Secure communication with NetSuite is subject to the Transport Layer Security (TLS) protocol. The cipher suites using the SHA1 algorithm are no longer considered secure. You should be using higher level cipher suites introduced with TLS 1.2 and that are supported for use in the NetSuite application. Cipher suites using the SHA-1 algorithm are targeted for deprecation in production accounts on January 28, 2020.
For more information, see Supported TLS Protocol and Cipher Suites, SuiteAnswers ID 84138. In this article, AES128-SHA is an example of a cipher suite that is scheduled for deprecation. The TLS protocol applies only to secure communication, that is to communicate with
