如何将bouncycastle getEncoded格式转换为X.509格式

import org.bouncycastle.asn1.ASN1InputStream;
import org.bouncycastle.cert.X509CertificateHolder;

// 读取bouncycastle getEncoded格式的证书数据
byte[] encodedCert = ...; // bouncycastle getEncoded格式的证书数据

// 将bouncycastle getEncoded格式的证书数据转换为X509CertificateHolder对象
ASN1InputStream asn1InputStream = new ASN1InputStream(encodedCert);
X509CertificateHolder certHolder = new X509CertificateHolder(asn1InputStream.readObject());
asn1InputStream.close();

// 获取证书版本
int version = certHolder.getVersion();

// 获取证书序列号
BigInteger serialNumber = certHolder.getSerialNumber();

// 获取证书颁发者信息
X500Name issuer = certHolder.getIssuer();

// 获取证书有效期
TimeRange validity = certHolder.getValidity();

import org.bouncycastle.cert.jcajce.JcaX509CertificateConverter;

// 将X509CertificateHolder对象转换为X.509格式的证书对象
JcaX509CertificateConverter certConverter = new JcaX509CertificateConverter();
java.security.cert.X509Certificate x509Cert = certConverter.getCertificate(certHolder);
