java.security.cert.CertificateParsingException

Question

尝试创建新证书时，我收到以下异常：

java.security.cert.CertificateParsingException：signed overrun，bytes = 224

    try
    {
        InputStream certificateStream = new ByteArrayInputStream(certificate);
        CertificateFactory cf = CertificateFactory.getInstance("X.509");
        Collection certificateCollection = cf.generateCertificates(certificateStream);
    }
    catch (CertificateException ex)
    {

    }

抛出异常： 集合certificateCollection = cf.generateCertificates（certificateStream）;

有人可以帮助我理解并解决这个问题吗？

Answer 1

这是well-functioning example based on your code。它使用FileInputStream。如果您使用ByteArray，请注意其中的数据：

import java.io.FileInputStream;
import java.io.InputStream;
import java.util.Collection;
import java.security.cert.CertificateFactory;
import java.security.cert.X509Certificate;
import java.security.cert.CertificateException;
import java.io.FileNotFoundException;

public class StackOverflow {

    public static void main(String[] args) throws FileNotFoundException, CertificateException {
        InputStream certificateStream = new FileInputStream("stackoverflow.cert");
        CertificateFactory cf = CertificateFactory.getInstance("X.509");
        Collection certificateCollection = cf.generateCertificates(certificateStream);
    }
}

好的，我的错误。

我从文件中读取证书，但我没有将其视为二进制文件...

二元阅读解决了这个问题。

非常感谢您的所有答案/评论！
