Bouncycastle：X509CertificateHolder 到 X509Certificate？

发布于 2024-11-16 02:44:13 字数 214 浏览 3 评论 0原文

在 r146 之前的版本中，可以直接创建 X509Certificate 对象。现在该 API 已弃用，新 API 仅提供一个 X509CertificateHolder 对象。

我找不到将 X509CertificateHolder 转换为 X509Certificate 的方法。

这怎么能做到呢？

我会回答我自己的问题，但不会删除它，以防其他人遇到同样的问题：

return new JcaX509CertificateConverter().getCertificate(certificateHolder);

对于属性证书：

return new X509V2AttributeCertificate(attributeCertificateHolder.getEncoded());

不好，因为它是编码和解码，但它有效。

I will answer to my own questions, but not delete it, in case someone else got the same problems:

return new JcaX509CertificateConverter().getCertificate(certificateHolder);

And for attribute certificates:

return new X509V2AttributeCertificate(attributeCertificateHolder.getEncoded());

Not nice, as it is encoding and decoding, but it works.

另一种选择是这个:)

CertificateFactory certFactory = CertificateFactory.getInstance("X.509");
InputStream in = new ByteArrayInputStream(certificateHolder.getEncoded());
X509Certificate cert = (X509Certificate) certFactory.generateCertificate(in);

Another option is this one :)

CertificateFactory certFactory = CertificateFactory.getInstance("X.509");
InputStream in = new ByteArrayInputStream(certificateHolder.getEncoded());
X509Certificate cert = (X509Certificate) certFactory.generateCertificate(in);

可以将 X509CertificateHolder 获取到 X509Certificate 和 toString。（代码第一句无关紧要）

X509CertificateHolder selfSignedCertificate = CertificateUtils.selfSignCertificate(certificationRequest, keyPair.getPrivate());
byte[] content = selfSignedCertificate.getEncoded();
CertificateFactory certificateFactory = CertificateFactory.getInstance("X.509");
X509Certificate cert = (X509Certificate) certificateFactory.generateCertificate(new ByteArrayInputStream(content));
logger.debug("cert: {}", cert.toString());

........

This is an possibility to get the X509CertificateHolder to X509Certificate and toString. (first sentence of the code is irrelevant)

X509CertificateHolder selfSignedCertificate = CertificateUtils.selfSignCertificate(certificationRequest, keyPair.getPrivate());
byte[] content = selfSignedCertificate.getEncoded();
CertificateFactory certificateFactory = CertificateFactory.getInstance("X.509");
X509Certificate cert = (X509Certificate) certificateFactory.generateCertificate(new ByteArrayInputStream(content));
logger.debug("cert: {}", cert.toString());

........
