读取pkcs12证书信息 [英] Reading pkcs12 certificate information

问题描述

我在读取证书信息时遇到问题。我想使用Java和Android中的bouncycastle库来阅读完整信息。现在，我只是在控制台中使用keytool命令：

I have a problem with reading certificate information. I want to read full information using java with bouncycastle library in Android programmatically. Now, i'm just using keytool command in console:

>keytool -list -keystore 1.p12 -storetype pkcs12 -v

有任何建议吗？

推荐答案

我找到了解决方案，主要思想是将证书转换为x509，然后获取SubjectDN和解析值。

I've found solution, the main idea is to cast certificate to x509, then get the SubjectDN and parse values.

public class TestClass {
    public static void main(String[] args) throws Exception {

        KeyStore p12 = KeyStore.getInstance("pkcs12");
        p12.load(new FileInputStream("pkcs.p12"), "password".toCharArray());
        Enumeration<String> e = p12.aliases();
        while (e.hasMoreElements()) {
            String alias = e.nextElement();
            X509Certificate c = (X509Certificate) p12.getCertificate(alias);
            Principal subject = c.getSubjectDN();
            String subjectArray[] = subject.toString().split(",");
            for (String s : subjectArray) {
                String[] str = s.trim().split("=");
                String key = str[0];
                String value = str[1];
                System.out.println(key + " - " + value);
            }
        }
    }
}
