在 Centos 7.2 NSS certutil 和其他使用 NSS 库的工具上,拒绝了我的证书并显示以下消息certutil: certificate is invalid: The certificate was signed using a signature algorithm that is disabled because it is not secure.
我在 Mac OS X 上使用 OpenSSL 0.9.8zh 创建了自己的根证书和中间证书。所有私钥均为 4096 位 RSA,消息摘要为 SHA256。证书颁发机构的配置大部分是从此处复制的:https://jamielinux.com/docs/openssl-certificate-authority/
然后我使用 Centos 上的 certutil 为服务器创建了私钥,并在 OS X 上再次使用中间 ca 对其进行了签名。我使用 certutil 将服务器证书、中间证书和根证书导入到服务器。
现在 certutil 正确显示证书:

验证中间证书和根证书均按预期工作。
nss 的版本是nss-3.21.0-9.el7_2.x86_64
您能发现证书中有什么错误吗,或者这可能是 nss 中的一个错误?
编辑:显然证书创建不正确。使用不同的参数和不同的工具再次创建证书解决了这个问题。
