什么是我的openssl和ssl默认CA Certs路径？ [英] what is my openssl and ssl Default CA Certs Path?

问题描述

后台：

我正在尝试与外部供应商建立SSL上下文连接以进行握手，然后使用xml进行通信连接。

I am trying to create an SSL context connection with an external vendor for handshake and then communicate using an xml over that connection.

clientCert = path["cert_path"]
clientKey = path["key_path"]
PROTOCOL = ssl.PROTOCOL_TLSv1
context = ssl.SSLContext(PROTOCOL)
context.load_default_certs()
context.load_cert_chain(clientCert, clientKey)
conn = httplib.HTTPSConnection(uri, 443, context=context) 
conn.request("POST", '/', headers=headers, body=signedRequest) # code breaks here
response = conn.getresponse()

但是此代码断言：

SSLError(1, u'[SSL: TLSV1_ALERT_UNKNOWN_CA] tlsv1 alert unknown ca (_ssl.c:590)

现在，我知道CA证书已正确放置在服务器上，某个地方的路径已经搞砸了。

Now, I know that the CA certificates are correctly placed on server, somewhere the path is getting messed up.

问题

我怎样才能看到这个 ssl 和 openssl 从中挑选CA Certs。

Openssl似乎正在建立正确的连接，所以我需要在这里明确提供ssl的路径。

How can i see what is the CA Path from which this ssl and openssl pick the CA Certs from.
Openssl seems to be making correct connection, so i need to provide the path to ssl explicitly here.

requests.utils 路径可以如下找到，寻找类似于 context.load_default_certs（）的理解

requests.utils path can be found up as below, looking for something similar to understand for context.load_default_certs()

In [1]: from requests.utils import DEFAULT_CA_BUNDLE_PATH

In [2]: print(DEFAULT_CA_BUNDLE_PATH)
/usr/local/python/path/site-packages/certifi/cacert.pem

推荐答案

确定...找到它：

命令将是 openssl version -a

[someone@somewhere ~]$ openssl  version -a
OpenSSL 1.0.1e-fips 11 Feb 2013

OPENSSLDIR: "/etc/pki/tls"
engines:  rdrand dynamic

输出中会有一个值 OPENSSLDIR ，这将是基本路径

There would be a value OPENSSLDIR in output, this would be the base path

OPENSSLDIR: "/etc/pki/tls"

大多数情况下，这将是一个符号链接，使用 ls -la 到此 OPENSSLDIR 路径

Most of the cases, this would be a symlink, use ls -la to this OPENSSLDIR path

[someone@somewhere ~]$ ls -la /etc/pki/tls
total 32
drwxr-xr-x.  5 root root  4096 Apr  6 10:09 .
drwxr-xr-x. 11 root root  4096 Apr  4 08:47 ..
lrwxrwxrwx   1 root root    19 Apr  6 10:09 cert.pem -> certs/ca-bundle.crt
drwxr-xr-x.  4 root root  4096 Mar 22 18:15 certs

进一步 ls -la

[someone@somewhere ~]$ ls -la /etc/pki/tls/certs/
total 1908
drwxr-xr-x. 4 root   root      4096 Mar 22 18:15 .
drwxr-xr-x. 5 root   root      4096 Apr  6 10:09 ..
lrwxrwxrwx  1 root   root        49 Apr  6 09:54 ca-bundle.crt -> /etc/pki/ca-trust/some/path/of/cert/tls-ca-bundle.pem

并获得实际路径：

/etc/pki/ca-trust/some/path/of/cert/tls-ca-bundle.pem
