• What is the cause and solution for SAP error message TRUST131 - RSA with MD5 ?

  The SAP error message TRUST131 typically indicates an issue related to the use of the MD5 hashing algorithm in the context of digital signatures or certificates. This error often arises when the system encounters a security concern regarding the use of MD5, which is considered weak and vulnerable to collision attacks.
  
  Cause:
  
  Weak Hash Algorithm: The error is triggered because the system is configured to reject the use of the MD5 hashing algorithm due to its known vulnerabilities.
  Certificate Issues: The error may also occur if a digital certificate is signed using MD5, which is not compliant with current security standards.
  Configuration Settings: The SAP system may have specific settings that enforce stronger cryptographic standards, leading to the rejection of MD5.
  
  
  Solution:
  
  Update Certificates: If the error is related to a digital certificate, you should replace any certificates that are signed with MD5 with those signed using a stronger algorithm, such as SHA-256.
  Check Configuration: Review the
