CA 证书仅添加到 ca-bundle-trust.crt

Question

环境：

Red Hat Enterprise Linux Server release 7.7 (Maipo)
# openssl version
OpenSSL 1.0.2g  1 Mar 2016

所以使用 OpenSSL 生成自签名证书，并将 cacert.pem 放在/etc/pki/ca-trust/source/anchors/.

现在根据 man from 的说法update-ca-trust，应该运行 cmd 将证书添加到信任库中，并且证书将被添加到/etc/pki/ca-trust/extracted/.

运行上述 cmd 后，我看到证书仅添加到/etc/pki/ca-trust/extracted/openssl/ca-bundle.trust.crt. 但是像 curl 这样的大多数应用程序都引用了/etc/pki/ca-trust/extracted/openssl/ca-bundle.crt链接到/etc/pki/tls/certs/ca-bundle.crt.

curl -v https://172.21.19.92/api
* About to connect() to 172.21.19.92 port 443 (#0)
*   Trying 172.21.19.92...
* Connected to 172.21.19.92 (172.21.19.92) port 443 (#0)
* Initializing NSS with certpath: sql:/etc/pki/nssdb
*   CAfile: /etc/pki/tls/certs/ca-bundle.crt

我知道传递--cacert选项是一种克服它的方法，但我想知道为什么update-ca-trust只更新ca-bundle-trust.crt而不是ca-bundle.crt或者 java Keystore 也提取了一个/etc/pki/ca-trust/extracted/java/cacerts

导入证书的实际命令/etc/pki/ca-trust/extracted/pem/tls-ca-bundle.pem是：

/usr/bin/p11-kit extract --format=pem-bundle --filter=ca-anchors --overwrite --comment --purpose server-auth $DEST/pem/tls-ca-bundle.pem

所以这里的过滤器是--filter=ca-anchors+ --purpose server-auth。当您生成证书时，您必须明确添加目的extendedKeyUsage=serverAuth：

openssl x509 -req -in $SRV_NAME.csr -CA $CA_NAME.crt -CAkey $CA_NAME.key -passin pass:"$PASS" -out $SRV_NAME.crt \
  -days 3650 -CAcreateserial \
  -extensions v3_ca \
  -extfile <(echo "[v3_ca]"; echo "extendedKeyUsage=serverAuth"; echo "subjectAltName=$SRV_DNS_NAMES_TEXT,email:$SRV_EMAIL")
