我正在使用FlexiEC提供程序來生成橢圓曲線公鑰。然後我將密鑰轉換成一個字節數組。之後，我想從這個字節數組中獲得這個公鑰的一個實例。每當我這樣做，我得到一個例外。來自字節數組的Flexiprovider橢圓曲線公用密鑰
的代碼如下：
import java.security.KeyPair;
import java.security.KeyFactory;
import java.security.KeyPairGenerator;
import java.security.PrivateKey;
import java.security.PublicKey;
import java.security.SecureRandom;
import java.security.Security;
import javax.crypto.Cipher;
import de.flexiprovider.common.ies.IESParameterSpec;
import de.flexiprovider.core.FlexiCoreProvider;
import de.flexiprovider.ec.FlexiECProvider;
import de.flexiprovider.ec.parameters.CurveParams;
import de.flexiprovider.ec.parameters.CurveRegistry.BrainpoolP160r1;
import de.flexiprovider.pki.X509EncodedKeySpec;
[...]
KeyPairGenerator kpg = KeyPairGenerator.getInstance("ECIES", "FlexiEC");
CurveParams ecParams = new BrainpoolP160r1();
kpg.initialize(ecParams, new SecureRandom());
KeyPair keyPair = kpg.generateKeyPair();
byte[] pubKey = keyPair.getPublic().getEncoded();
X509EncodedKeySpec pubKeySpec = new X509EncodedKeySpec(pubKey);
KeyFactory keyFactory = KeyFactory.getInstance("ECIES", "FlexiEC");
PublicKey pk = keyFactory.generatePublic(pubKeySpec);
唯一的例外是：
Exception in thread "main" de.flexiprovider.api.exceptions.InvalidKeySpecException: java.lang.RuntimeException: java.security.InvalidAlgorithmParameterException: Caught IOException("Unknown named curve: 1.3.36.3.3.2.8.1.1.1")

如何從字節數組正確恢復的關鍵？
