本文整理了Java中javax.security.cert.X509Certificate类的一些代码示例，展示了X509Certificate类的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。X509Certificate类的具体详情如下：
包路径：javax.security.cert.X509Certificate
类名称：X509Certificate

X509Certificate介绍

[英]Abstract base class for X.509 certificates.

This represents a standard way for accessing the attributes of X.509 v1 certificates.

Note: This package is provided only for compatibility reasons. It contains a simplified version of the java.security.cert package that was previously used by JSSE (Java SSL package). All applications that do not have to be compatible with older versions of JSSE (that is before Java SDK 1.5) should only use java.security.cert.
