让我们加密 - nginx - OCSP 装订

我想在我的 nginx 服务器中启用 OCSP 装订。我在用着

  • nginx版本：nginx/1.6.2
  • 德比安
  • 让我们加密证书

我在这件事上真的没有经验，所以这可能是一个微不足道的问题。

这是我的 nginx 安全配置

    ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
    ssl_prefer_server_ciphers on;
    ssl_session_cache shared:SSL:10m;
    ssl_dhparam /etc/ssl/private/dhparams_4096.pem;

这是我的站点/服务器安全配置：

    add_header Strict-Transport-Security "max-age=31536000; includeSubdomains; preload";

    # All files have been generated by Let's encrypt
    ssl_certificate /etc/letsencrypt/live/myexample.org/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/myexample.org/privkey.pem;

    # Everything below this line was added to enable OCSP stapling
    # What is that (generated file) and is that required at all?
    ssl_trusted_certificate /etc/letsencrypt/live/myexample.org/chain.pem;

    ssl_stapling on;
    ssl_stapling_verify on;
    resolver 8.8.8.8 8.8.4.4 valid=300s;
    resolver_timeout 5s;

我读到这足以启用 OCSP 装订。

但如果我用它来测试它

 openssl s_client -connect myexample.org:443 -tls1 -tlsextdebug -status

我会得到以下回复：

TLS server extension "renegotiation info" (id=65281), len=1
0001 - <SPACES/NULS>
TLS server extension "EC point formats" (id=11), len=4
0000 - 03 00 01 02                                       ....
TLS server extension "session ticket" (id=35), len=0
TLS server extension "heartbeat" (id=15), len=1
0000 - 01                                                .
OCSP response: no response sent
depth=1 C = US, O = Let's Encrypt, CN = Let's Encrypt Authority X1
verify error:num=20:unable to get local issuer certificate
verify return:0
---
Certificate chain
 0 s:/CN=myexample.org
   i:/C=US/O=Let's Encrypt/CN=Let's Encrypt Authority X1
 1 s:/C=US/O=Let's Encrypt/CN=Let's Encrypt Authority X1
   i:/O=Digital Signature Trust Co./CN=DST Root CA X3
---
[...]

尤其

OCSP response: no response sent

我究竟做错了什么？

证书层次结构：

  • DST 根 CA X3
    • 让我们加密权限 X1
      • myexample.org

编辑：

OCSP: URI: http://ocsp.int-x1.letsencrypt.org/
CA-Issuer: URI: http://cert.int-x1.letsencrypt.org/

答案1

按照标准 nginx 设置，您不需要指定ssl_trusted_certificate链。以下内容应该足够了：

ssl_certificate /etc/letsencrypt/live/myexample.org/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/myexample.org/privkey.pem;
ssl_stapling on;
ssl_stapling_verify on;

看这里了解更多背景信息。

答案2

我根据我找到的教程找到了解决方案那里:

cd /etc/ssl/private
wget -O - https://letsencrypt.org/certs/isrgrootx1.pem https://letsencrypt.org/certs/lets-encrypt-x1-cross-signed.pem https://letsencrypt.org/certs/letsencryptauthorityx1.pem https://www.identrust.com/certificates/trustid/root-download-x3.html | tee -a ca-certs.pem> /dev/null

并将其添加到您的站点/服务器配置中

ssl_stapling on;
ssl_stapling_verify on;
ssl_trusted_certificate /etc/ssl/private/ca-certs.pem;

重新加载您的配置

重要提示：打开您的浏览器并访问您的网页一次。

然后您可以使用以下命令在本地测试您的服务器：

openssl s_client -connect myexample.org:443 -tls1 -tlsextdebug -status

您很可能会得到这样的有效回复

OCSP response:
======================================
OCSP Response Data:
    OCSP Response Status: successful (0x0)
    Response Type: Basic OCSP Response
    Version: 1 (0x0)
    Responder Id: C = US, O = Let's Encrypt, CN = Let's Encrypt Authority X1

如果您得到一个，请不要担心

Verify return code: 20 (unable to get local issuer certificate)

在底部还有，Let's encrypt 证书尚未位于默认受信任证书存储中。 （我没有太多的ssl经验，所以我可能是错的）

如果在服务器上执行以下cmd，则不会出现该错误：

openssl s_client -CApath /etc/ssl/private/ -connect myexample.org:443 -tls1 -tlsextdebug -status

之后，您可以使用以下命令测试您的服务器：

请注意，目前 ssllabs 测试不会获取 OCSP 响应。我认为这是因为“让我们加密”证书尚未位于默认的受信任证书存储中。
