• What is the cause and solution for SAP error message TRUST130 - DSA with SHA-1 ?

  The SAP error message TRUST130 DSA with SHA-1 typically indicates an issue related to the digital signature algorithm (DSA) and the SHA-1 hashing algorithm used in the context of digital certificates or signatures. This error often arises when the system encounters a certificate that uses SHA-1, which is considered weak and insecure by modern standards.
  Cause:
  
  Outdated Cryptographic Standards: The error is primarily caused by the use of SHA-1, which has been deprecated due to vulnerabilities that make it susceptible to collision attacks.
  Certificate Issues: The digital certificate being used may be signed with SHA-1, which is no longer considered secure.
  Configuration Issues: The SAP system may be configured to reject certificates that do not meet certain security standards.
  
  Solution:
  
  
  Update Certificates: 
  
  Replace any certificates that are signed with SHA-1 with those signed using stronger algorithms, such as SHA-256 or SHA-3.
  Ensure that all relevant certificates in the trust store are updated.
  
  
  
  Check SAP Cryptographic Library:
  
  Ensure that you are using an up-to-date version of the SAP Cryptographic Library, which supports stronger algorithms.
  You can download the latest version from the SAP Service Marketplace.
  
  
  
  Adjust Trust Settings:
  
  Review the trust settings in your SAP system. You may need to adjust the settings to accept newer algorithms or to reject older ones.
  This can typically be done in transaction STRUST (Trust Manager) where you manage SSL certificates and trust relationships.
  
  
  
  System Configuration:
  
  Ensure that your SAP system is configured to use secure protocols and algorithms. This may involve updating system parameters or configuration files.
  
  
  
  Consult Documentation:
  
  Refer to SAP Notes and documentation for specific guidance on handling cryptographic issues and updating certificates.
  
  
  
  Related Information:
  
  SAP Notes: Check for relevant SAP Notes that address the TRUST130 error or provide guidance on cryptographic standards.
  Security Best Practices: Familiarize yourself with security best practices for managing certificates and cryptographic algorithms in SAP environments.
  Regular Audits: Conduct regular audits of your certificates and cryptographic settings to ensure compliance with current security standards.
  
  By addressing the underlying issues related to SHA-1 and ensuring that your SAP system is using up-to-date cryptographic practices, you can resolve the TRUST130 error and enhance the security of your SAP environment.
