• What is the cause and solution for SAP error message TRUST005 - Certificate too big ?

  The SAP error message TRUST005: Certificate too big typically occurs when the size of a digital certificate exceeds the maximum allowed size for processing in the SAP system. This can happen during various operations involving SSL/TLS connections, such as when importing or using certificates in the SAP Trust Manager (transaction code STRUST).
  Cause:
  
  Certificate Size: The certificate being imported or used is larger than the maximum size that the SAP system can handle. This can happen with certain types of certificates, especially if they include a lot of information or if they are not properly formatted.
  Configuration Issues: There may be configuration settings in the SAP system that limit the size of certificates that can be processed.
  Encoding Issues: The certificate may be improperly encoded or formatted, leading to an inflated size when processed by SAP.
  
  Solution:
  
  Check Certificate Size: Verify the size of the certificate you are trying to import. If it exceeds the limits, consider using a smaller certificate or breaking it down into smaller components if applicable.
  Use PEM Format: Ensure that the certificate is in the correct format (e.g., PEM format). Sometimes, converting the certificate to a different format can help reduce its size.
  Split the Certificate: If the certificate contains multiple components (like a chain of trust), consider splitting them into individual certificates and importing them separately.
  Update SAP Kernel: Ensure that your SAP system is running on an up-to-date kernel version, as newer versions may have improved handling for larger certificates.
  Check SAP Notes: Look for relevant SAP Notes that may address this issue. SAP frequently releases updates and patches that can resolve specific errors.
  Consult Documentation: Review the SAP documentation for any specific guidelines regarding certificate sizes and formats.
