• What is the cause and solution for SAP error message 1S010 - SSF error: Invalid hash algorithm ?

  The SAP error message 1S010 SSF error: Invalid hash algorithm typically indicates an issue with the Secure Store and Forward (SSF) interface in SAP, particularly related to cryptographic operations. This error can occur when the system is trying to use a hash algorithm that is not supported or is incorrectly configured.
  Causes:
  
  Unsupported Hash Algorithm: The hash algorithm specified in the SSF configuration may not be supported by the underlying cryptographic library or the operating system.
  Configuration Issues: Incorrect configuration settings in the SSF parameters or the cryptographic settings in the SAP system.
  Missing or Corrupted Cryptographic Libraries: The required cryptographic libraries may be missing, outdated, or corrupted.
  SAP Kernel Version: The version of the SAP kernel may not support the specified hash algorithm.
  
  Solutions:
  
  
  Check SSF Configuration:
  
  Go to transaction SSFC (SSF Configuration) and verify the settings for the hash algorithm. Ensure that the algorithm being used is supported.
  You can also check the parameters in transaction RZ10 to see if any relevant parameters are set incorrectly.
  
  
  
  Update Cryptographic Libraries:
  
  Ensure that the cryptographic libraries (like OpenSSL) are up to date and properly installed on the server.
  If you are using a specific cryptographic provider, ensure that it supports the hash algorithm you are trying to use.
  
  
  
  Review SAP Notes:
  
  Check for any relevant SAP Notes that might address this issue. SAP frequently releases notes that provide fixes or workarounds for known issues.
  Use transaction SNOTE to apply any relevant notes.
  
  
  
  Kernel Upgrade:
  
  If the kernel version is outdated, consider upgrading to a newer version that supports the required hash algorithms.
  
  
  
  Consult Documentation:
  
  Review the SAP documentation for SSF and cryptographic settings to ensure that all configurations are correct.
