Threatgrid设备不接受CA证书

简介

当从证书文件添加内容时，Threatgrid设备不接受证书并显示错误，即这是“Not a client/server CA cert”，错误如下所示：

解决方案

有可能相关证书没有必要的扩展，因此Threatgrid设备无法接受。要使CA证书被threatgrid接受，它必须具有正确的CA扩展。要检查此项：

步骤 1：为了验证证书，您可以执行此openssl命令。

openssl x509 -in poke.fireamp.pem -text

步骤 2：此处显示的内容如下：

第3步：这表示CA扩展不存在。这些是CA证书上预期的扩展。

            X509v3 Basic Constraints: critical
                CA:TRUE

步骤 4：确保证书有这些扩展可用，如果不可用，则必须要求证书提供商与这些扩展共享CA证书。如果您已使用OpenSSL创建证书，这些命令将帮助您生成具有正确扩展名的CA证书。

openssl genrsa -out rootCA.key 2048

openssl req \
-addext basicConstraints=critical,CA:TRUE\
-outform pem -out rootCA.pem \
-key rootCA.key -new -x509 \
-days "1000"
