从byte []生成X509Certificate？ [英] Generate X509Certificate from byte[]?

问题描述

是否有可能从byte []生成java.security.cert.X509Certificate？

Is there a possibility to generate an java.security.cert.X509Certificate from an byte[]?

推荐答案

当然。

证书对象可以由 CertificateFactory - 特别是配置为创建X509证书的一个。这可以像这样创建：

The certificate objects can be created by an instance of CertificateFactory - in particular, one configured to create X509 certificates. This can be created like so:

CertificateFactory certFactory = CertificateFactory.getInstance("X.509");

然后你需要传递一个包含证书字节的InputStream。这可以通过将字节数组包装在 ByteArrayInputStream <中来实现。 / a>：

Then you need to pass it an InputStream containing the bytes of the certificate. This can be achieved by wrapping your byte array in a ByteArrayInputStream:

InputStream in = new ByteArrayInputStream(bytes);
X509Certificate cert = (X509Certificate)certFactory.generateCertificate(in);
