• What is the cause and solution for SAP error message TRUST062 - Cannot determine public key algorithm of PSE ?

  The SAP error message TRUST062: Cannot determine public key algorithm of PSE typically occurs in the context of SAP's security infrastructure, particularly when dealing with the Personal Security Environment (PSE) and digital certificates. This error indicates that the system is unable to identify the public key algorithm associated with the PSE, which is essential for cryptographic operations.
  Causes:
  
  Corrupted PSE: The PSE file may be corrupted or improperly configured, leading to the inability to read the public key algorithm.
  Missing or Invalid Certificates: The required certificates may be missing, invalid, or not properly imported into the PSE.
  Incompatible Key Algorithm: The key algorithm used in the PSE may not be supported or recognized by the SAP system.
  
  Configuration Issues: There may be issues with the configuration of the SAP system's security settings or the PSE itself.
  
  Solutions:
  
  
  Check PSE Integrity:
  
  Use transaction STRUST to check the integrity of the PSE. You can also regenerate the PSE if necessary.
