I am having a trouble related with SSL certificates.
I have a server running service in a docker container, I installed Caddy and get the SSL certificate for the site. Now, from other server I want to consume the service with HTTPS, but I get:
x509: certificate signed by unknown authority exit status 1
And, it seems to be a common issue when using docker + SSL. What should I do? thanks
Install the ca-certificates package.
I have installed DockerToolbox-1.12.0.exe on Windows 7. The corporate proxy provides its own certificate to do MITM.
I have configured boot2docker to use the proxy by exporting environment variables in .profile.
I am still not able to do
docker run hello-world
as i am getting - docker: Error while pulling image: Get https://index.docker.io/v1/repositories/library/hello-world/images: x509: certificate signed by unknown authority.
Please anyone help.
I have one chef-server version 12.0.1 and can connect linux (rhel/centos) systems to the chef-server with knife bootstrap but cannot with windows and locally on my rhel client knife ssl check fails.
I have two problems but I think they are both related.
Problem 1 - knife ssl check fails:
Connecting to host chef-server:443
ERROR: The SSL certificate of chef-server could not be verified
Problem 2 - bootstrap windows server fails:
ERROR: SSL Validation failure connecting to host: chef-server - SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed
Chef encountered an error attempting to create the client "desktop"
I have tried a number of things:
1) knife ssl fetch - no changes
2) I have a signed digicert crt on the server which is accepted by the management-console and chrome web browser
3) I have changed set this in the chef-server.rb
nginx['ssl_certificate'] = "/var/opt/opscode/nginx/ca/hostname.crt"
nginx['ssl_certificate_key'] = "/var/opt/opscode/nginx/ca/hostname.key"
which go to the signed certs.
Anything else I should be trying or am I being a plank?
Try running these commands on your Chef server:
mkdir /root/.chef/trusted_certs
cp /var/opt/chef-server/nginx/ca/YOUR_SERVER'S_HOSTNAME.crt /root/.chef/trusted_certs/
I was having the same problem and it was fixed after I looked through this article, and tried out the steps it gave: http://jtimberman.housepub.org/blog/2014/12/11/chef-12-fix-untrusted-self-sign-certs/
I was having the same issue using a valid wildcard certificate, although it was linux rather than windows. Looks like the issue is that the chef client uses openssl and didn't have the CA and root certificates. I was getting errors when I ran the following from the chef client server:
openssl s_client -connect chef_server_url*:443 -showcerts
I solved my issue by browsing to the chef server, inspecting the certs and exporting each cert in the chain to a single file, ordered with the issued certificate at the top, and the root at the bottom. I then used this bundled-cert as the certificate file in the chef server config file and reconfigured chef.
I've already purchased the SSL Certifcate from DigiCert and install it into my Nexus server (running in tomcat, jks)
It works well in firefox and chrome(green address bar indicates that a valid certificate received) , builds could be downloaded from Nexus WebUI too.
But, wget could not get the result without --no-check-certificate
something like
ERROR: cannot verify mydomain.com's certificate, issued by `/C=US/O=DigiCert Inc/OU=www.digicert.com/CN=DigiCert High Assurance CA-3':
Unable to locally verify the issuer's authority.
To connect to mydomain.com insecurely, use `--no-check-certificate'.
Unable to establish SSL connection.
Found something,
SSL connection fails with wget, curl, but succeed with firefox and lynx
linux wget not certified?
But neither of them gives a final solution, I want to know whether there are some (special) configurations on Nexus or this's a bug of wget command?
Google return many results about "digitcert wget",but I cannot find a clue either, Thank you!
You need to add the DigiCert root certificate to a store accessible by wget:

I am getting the below error while making ssl connection with self signed certificate.
"Peer certificate cannot be authenticated with known CA certificates"
It is working fine with CA signed certificate.
I am setting the below using curl_easy_setopt().
curl_easy_setopt(MyContext, CURLOPT_CAPATH, CA_CERTIFICATE_PATH)
curl_easy_setopt(MyContext, CURLOPT_SSL_VERIFYPEER,TRUE);
The curl version:
libcurl-7.19.7-26
Openssl version is:
0_9_8u
Please let me know how to solve this issue.
By default CURL will generally verify the SSL certificate to see if its valid and issued by an accepted CA. To do this, curl uses a bundled set of CA certificates.
If you'd like to turn off curl's verification of the certificate, use the -k (or --insecure) option. Here's an example:
curl --noproxy -k \* -D - https://127.0.0.1:443/some-secure-endpoint

For php it is possible to switch off curl's verification of the certificate (see warning below) e.g. for curl_exec
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
http://php.net/manual/en/function.curl-setopt.php
(evaluate the security risk yourself, in my case it was on a partner company's server and the file required contained no secure information - just happened to be on a secure server)
We fixed a similar issue on CentOS 6 by updating curl to the latest version available in the standard repositories and installing the newest ca-certificates bundle:
yum update curl
yum install ca-certificates
libcurl performs peer SSL certificate verification by default. This is done
by using CA cert bundle that the SSL library can use to make sure the peer's
server certificate is valid.
If you communicate with HTTPS or FTPS servers using certificates that are
signed by CAs present in the bundle, you can be sure that the remote server
really is the one it claims to be.
Until 7.18.0, curl bundled a severely outdated ca bundle file that was
installed by default. These days, the curl archives include no ca certs at
all. You need to get them elsewhere. See below for example.

Though this error happened in the case of using git clone rather than with using curl, I've recently stumbled across an identical error message:
Peer certificate cannot be authenticated with known CA certificates
Similar to Arth's findings, something that worked for CentOS 6 (in order to successfully use HTTPS URLs with git clone for related GitLab repositories) involved updating the trusted certificates on the server (i.e., the server that is using HTTPS), using the following steps:
sudo yum install ca-certificates
sudo update-ca-trust enable
sudo cp /path/to/your_new_cert.crt /etc/pki/ca-trust/source/anchors/
sudo update-ca-trust extract
Perhaps the same certificate steps can be applied for the case of curl (or other similar scenarios) for users on CentOS in the future.

In 'C'
curl_easy_setopt(curl_handle, CURLOPT_SSL_VERIFYPEER, 0);
worked for me
As we checked and observed/ Found in Centos 8 .
Due to Proxy issue your packages not allowing you to get accessible to update or download any packages.
try to add sslverify=0 in file /etc/dnf/dnf.conf
Its worked for me.
Also make sure you must have proper internet acess on your server.
