ssl - 802.1ar 安全设备身份证书

Question

有人知道常规 x509v3 证书与安全设备身份证书之间的区别吗？我知道对于设备身份证书，它们确实限制了您可以在某些字段中使用的内容(想到签名算法以及到期时间)，并且 subjectName 对设备来说是唯一的，但还有什么不同。假设我要按如下方式生成证书:

$ openssl ecparam -out priv_key.pem -name secp384r1 -genkey
$ openssl req -new -key priv_key.pem -x509 -nodes -out cert.pem

然后我的证书看起来像这样:

$ openssl x509 -text -noout -in cert.pem

要将此证书视为安全设备身份证书还需要什么？

Answer 1

没有通用的答案，除了这个:阅读设备文档。不同厂商对证书的要求不同。并且没有像“常规 x509v3”证书这样的术语。通常，它们在私钥和公钥用法上有所不同。阅读文档，您应该找到有关证书要求的信息。

and then my cert looks like this:

这是 CA，不是终端实体证书。 CA 证书用于签署其他证书和 CRL。
