• 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  Outdated Cryptographic Standards: The error is primarily caused by the use of SHA-1, which has been deprecated due to vulnerabilities that make it susceptible to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.
