查看p10文件内容

1.通过openssl查看

[root@ahdjg ~]#openssl req -in cerseq.csr -text #cerseq.csr存放的是p10的base64格式数据
unable to load X509 request
140239849273232:error:0906D06C:PEM routines:PEM_read_bio:no start line:pem_lib.c:707:Expecting: CERTIFICATE REQUEST

但是这种方式报错，具体不知道，哪里的问题。选择以代码的方式来查看p10内容，是正常的。

2.通过Java代码查看p10内容

public static void main(String[] args) {
        getPublicKeyByP10();
    }
    public static void getPublicKeyByP10() {
        try {
            //模拟读取PKCS10格式文件得到的数据,为防泄密这里的p10是假数据
            String p10str ="MIIBHDCBxAIBATBiMRwwGgYDVQQ0DxPmipXmoIfmtYvor5XljZXkvY0xMRQwEgYDVQQLDAt6aGFvdG91YmlhbzENMAsGA1UECwwEVEJEVzEQMA4GA1UECgwHU0lOT1BFQzELMAkGA1UEBgwCQ04wWTATBgcqhkjOPQIBBggqgRzPVQGCLQNCAASDqxbIMK7tJihJy3OFXvM2l4wr6AxRtMYAx6s6rlQ2pKPchdBXKvg0vF9/X+cfdoHvzRQiYLZDUW6WqhlzyK0CoAAwCgYIKoEcz1UBg3UDRwAw0AIgToHccXHyihKj3V/xudKGlQyc6yxdFvl9lpbJxTcdBFxxIH7nbj7gQDn3gzVkVVQAcWuhc+t7JCbW2MNa6pwx1SSw";
            //p10str = CertHelper.removeTagP10(p10str); -- 这个方法是为了把开始和结束标签去掉
            //创建证书请求
            PKCS10CertificationRequest pkcs10CertificationRequest = new PKCS10CertificationRequest(Base64.getMimeDecoder().decode(p10str));
            //获取提供的个人信息
            System.out.println(pkcs10CertificationRequest.getSubject());
            //获取公钥
            SubjectPublicKeyInfo subjectPublicKeyInfo = pkcs10CertificationRequest.getSubjectPublicKeyInfo();
            System.out.println(Base64.getMimeEncoder().encodeToString(subjectPublicKeyInfo.getEncoded()));

        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }

运行结果如下：
