在Java中进行SM2加密和解密,您可以使用Bouncy Castle密码库来实现。下面是一个简单的示例代码:
```java
import org.bouncycastle.crypto.AsymmetricCipherKeyPair;
import org.bouncycastle.crypto.digests.SM3Digest;
import org.bouncycastle.crypto.engines.SM2Engine;
import org.bouncycastle.crypto.generators.ECKeyPairGenerator;
import org.bouncycastle.crypto.params.*;
import org.bouncycastle.crypto.signers.SM2Signer;
import org.bouncycastle.crypto.util.PrivateKeyFactory;
import org.bouncycastle.crypto.util.PublicKeyFactory;
import org.bouncycastle.jce.provider.BouncyCastleProvider;
import java.security.Security;
public class SM2Example {
public static void main(String[] args) throws Exception {
Security.addProvider(new BouncyCastleProvider());
// 生成密钥对
ECKeyPairGenerator generator = new ECKeyPairGenerator();
generator.init(new ECKeyGenerationParameters(SM2NamedCurves.sm2p256v1(), new SecureRandom()));
