CCARDEC001 - Details

• The SAP error message CCARDEC001 indicates that the system encountered an issue while trying to generate a hash value using the SHA1 algorithm. This error typically arises in the context of data encryption or digital signatures, where hash values are used to ensure data integrity and authenticity.
  Causes:
  
  Missing or Incorrect Configuration: The SHA1 algorithm may not be properly configured in the SAP system. This could be due to missing libraries or incorrect settings in the cryptographic framework.
  Unsupported Algorithm: The system may not support the SHA1 algorithm due to security policies or updates that have deprecated its use.
  Corrupted Data: The data being processed may be corrupted or not in the expected format, leading to the failure in generating a hash.
  System Updates or Patches: Recent updates or patches to the SAP system may have affected the cryptographic functions or libraries.
  
  Solutions:
  
  Check Configuration: Verify the configuration settings for cryptographic algorithms in the SAP system. Ensure
