我对以下代码有疑问。当我尝试签署xml文件时，它崩溃了。 字段PIN固定到智能卡，并且100％正确。我不知道哪里出了问题。有人可以帮助我吗？
PKCS11KeyStoreKeyingDataProvider ptccKeyingDataProv = new PKCS11KeyStoreKeyingDataProvider(
"C:\\Windows\\System32\\cryptoCertum3PKCS.dll", "CertumQCA2017",
new FirstCertificateSelector(), new DirectPasswordProvider(PIN), null, false);
XadesSigner signer = (XadesSigner) new XadesBesSigningProfile(ptccKeyingDataProv)
.newSigner();
new Enveloped(signer).sign(elemToSign);
我在新的Enveloped（signer）.sign（elemToSign）行有CKR_FUNCTION_FAILED错误；
