C++ C++；调用libtomcrypt ecc对使用OpenSSL创建的数据进行签名和验证

我正在寻找使用OpenSSL命令行创建的输入调用libtomcrypt ecc签名和验证代码的示例。我使用prime256v1曲线创建了私钥和公钥，为文本文件创建了签名，并使用命令行对其进行了验证。我已经把这些密钥和签名插入到我的C++测试驱动程序中，并使用LIbTyCurPT方法来导入这些密钥。我使用openssl命令行创建了文本文件的散列，并将其放入我的测试驱动程序中，但是当我调用libtomcrypt ecc_verify_散列方法时，它无法验证。在这一点上，我已经验证了密钥和签名是否正确导入，因此我不确定我是否做得不正确

这是我的测试驱动程序的代码。在此方面的任何帮助都将不胜感激
