• What is the cause and solution for SAP error message TRUST134 - RSA with SHA-384 ?

  The SAP error message TRUST134 typically indicates an issue related to the cryptographic algorithms used for digital signatures or certificates, specifically involving RSA with SHA-384. This error can arise in various contexts, such as when dealing with secure communications, digital signatures, or certificate validation.
  Cause:
  
  Unsupported Algorithm: The error may occur if the system does not support the RSA with SHA-384 algorithm. This can happen if the cryptographic libraries or configurations in your SAP system do not include support for this specific algorithm.
  Certificate Issues: The error might also be related to the certificates being used. If a certificate is signed using RSA with SHA-384 and the system does not recognize or support this signature algorithm, it will trigger the TRUST134 error.
  Configuration Problems: There may be misconfigurations in the trust store or the cryptographic settings in the SAP system.
  
  Solution:
  
  Update Cryptographic Libraries: Ensure that your SAP system is updated to the latest version, which may include support for newer cryptographic algorithms. Check the SAP Notes and documentation for any updates related to cryptographic support.
  Check Certificate Validity: Verify that the certificates being used are valid and correctly configured. Ensure that they are not expired and that they are signed with an algorithm supported by your SAP system.
  Modify Cryptographic Settings: If necessary, adjust the cryptographic settings in your SAP system to support RSA with SHA-384. This may involve modifying the configuration files or settings in the SAP NetWeaver Administrator or the relevant transaction codes.
  Consult SAP Notes: Look for specific SAP Notes related to the TRUST134 error. SAP frequently publishes notes that provide guidance on resolving specific issues, including cryptographic errors.
  Engage SAP Support: If the issue persists after trying the above solutions, consider reaching out to SAP Support for assistance. They can provide more detailed guidance based on your specific system configuration and version.
  
  Related Information:
  
  SAP Cryptographic Library: Ensure that you are using the appropriate version of the SAP Cryptographic Library, which may include support for various algorithms.
  Security Policies: Review your organization's security policies regarding cryptographic algorithms to ensure compliance and compatibility with SAP systems.
  Documentation: Refer to the official SAP documentation for information on supported algorithms and configurations related to digital signatures and certificates.
  
  By addressing the underlying causes and following the suggested solutions, you should be able to resolve the TRUST134 error in your SAP environment.
