Symptom

Please find the following list of Supporting Cipher of BYD. 

Environment

SAP Business ByDesign

Reproducing the Issue

Cause

To communicate with BYD from/to an external application, it is necessary to ensure that target server support at least one of the ciphers from the listed Supported Ciphers.

Resolution

The following Server ciphers are supported:

  • TLSv1.3: TLS_AES_256_GCM_SHA384 (256 bits)
  • TLSv1.3: TLS_AES_128_GCM_SHA256 (128 bits)
  • TLSv1.2: ECDHE-RSA-AES128-GCM-SHA256 (128 bits)
  • TLSv1.2: ECDHE-RSA-AES256-GCM-SHA384 (256 bits)
  • TLSv1.2: ECDHE-RSA-AES128-SHA (128 bits)
  • TLSv1.2: ECDHE-RSA-AES256-SHA384 (256 bits)
  • TLSv1.2: ECDHE-RSA-AES256-SHA (256 bits)
  • TLSv1.2: AES128-GCM-SHA256 (128 bits)
  • TLSv1.2: AES256-GCM-SHA384 (256 bits)
  • TLSv1.2: AES128-SHA (128 bits)
  • TLSv1.2: AES256-SHA (256 bits)

It's possible to use the website https://www.ssl.org/ to check the supported ciphers.
