Issue Details

I am interested in using the LabVIEW SMTP Email VIs, however when I try to use them with the Ciphers I have available I get the following error.

Error -715056 occurred at Start TLS
LabVIEW: (Hex 0xFFF516D0) Unsupported cipher.

What are the supported Ciphers that these functions accept?

Solution

The following is the list of supported ciphers by the SMTP Email VIs.
 
  • ECDHE-ECDSA-AES128-GCM-SHA256
  • ECDHE-RSA-AES128-GCM-SHA256
  • DHE-RSA-AES128-GCM-SHA256
  • ECDHE-ECDSA-AES256-GCM-SHA384
  • ECDHE-RSA-AES256-GCM-SHA384
  • DHE-RSA-AES256-GCM-SHA384
  • ECDHE-ECDSA-AES256-GCM-SHA256
  • ECDHE-RSA-AES256-GCM-SHA256
  • DHE-RSA-AES256-GCM-SHA256

 

Additional Information

This list includes a limited set of the TLS 1.2 supported ciphers, in part as a design decision to avoid the use of ciphers that would be out-of-date in the future, and could expose security risks in their applications.
