我从一个 xml 文件中提取了 x509certificate 数据

      TXNohQWlq2z6Zg8Oxzsy5JoVV....==
            </X509Certificate>
        </X509Data>

如何根据这些数据创建 Java X509Certificate?

How can I create Java X509Certificate from this data?

我已经试过了

    CertificateFactory cf = CertificateFactory.getInstance(X_509);
    ByteArrayInputStream bais = new ByteArrayInputStream(certBytes);
    X509Certificate x509cert = (X509Certificate) cf.generateCertificate(bais);
    bais.close();

但是出现错误

java.security.cert.CertificateParsingException: invalid DER-encoded certificate data.

感谢任何帮助.

推荐答案

那些字节是 PEM.Java 可以处理它，但如果将它包含在-----BEGIN CERTIFICATE-----"和-----END CERTIFICATE-----"之间

those bytes are PEM. And Java can handle it but if enclose it between "-----BEGIN CERTIFICATE-----" and "-----END CERTIFICATE-----"
