示例1: decryptUnknownKeyfile

 /**
  * @brief Decrypt a keyfile without knowing how it was encrypted
  * @param string $filePath
  * @param string $fileOwner
  * @param string $privateKey
  * @return bool|string
  * @note Checks whether file was encrypted with openssl_seal or
  *       openssl_encrypt, and decrypts accrdingly
  * @note This was used when 2 types of encryption for keyfiles was used,
  *       but now we've switched to exclusively using openssl_seal()
