  Common causes include:
  
  Incorrect or missing encryption keys or certificates: The system cannot find or access the required key or certificate to perform encryption/decryption.
  Mismatch in encryption algorithms: The sender and receiver do not agree on the encryption algorithm or parameters.
  Corrupted or invalid security tokens: The security token used for encryption is invalid or expired.
  Configuration errors in WS-Security settings: Incorrect setup in the SAP Web Service Security configuration.
  Issues with the SAP Cryptographic Library (CommonCryptoLib): Missing or incompatible cryptographic libraries.
  Problems with the keystore or PSE (Personal Security Environment): The PSE might be corrupted or not properly maintained.
