I can connect fine with Python to any external https site without this error:
SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1108)')))
But I have a local webserver on my laptop with a self-signed certificate that works fine in itself but Python generates an _ssl.c:1108 error when I try to connect to it.
Any ideas?
The python client does not have access and trust the CA certificate that signed the web server certificate. In your case that is the self-signed web server certificate.
To get the python client working, you can do the following:
disable certificate verification. That is not a good idea but I guess is ok for a quick test. The emphasis is on "it is not recommended".
Download the self-signed certificate and make it accessible to the python client and specify it as trusted CA certificate.
Download and install a certificate from well known CAs such as LetsEncrypt (free) or commercial CAs. This is the recommended approach.
You could go into depth on the items mentioned herein and get a conceptual understanding how TLS operates.
EDIT 1: You could also get a free certificate from LetsEncrypt CA. Or you could get a free test certificate from most of the commercial CAs like DigiCert etc. See this link for getting and installing a free test certificate signed by a DigiCert test CA.
See this for details on python client configuration for TLS.
I need to enable SSL in tomcat 8.5 using x. 509 CA certificate.

I'm trying to send email using MailKit through provider's SMTP server using valid Let's Encrypt Authority X3 certificate. On Windows everything works great, but when sending from Ubuntu I get certificate error:
MailKit.Security.SslHandshakeException: An error occurred while attempting to establish an SSL or TLS connection.
One possibility is that you are trying to connect to a port which does not support SSL/TLS.
The other possibility is that the SSL certificate presented by the server is not trusted by the system for one or more of the following reasons:
The server is using a self-signed certificate which cannot be verified.
The local system is missing a Root or Intermediate certificate needed to verify the server's certificate. (I believe this is my problem?)
The certificate presented by the server is expired or invalid.
When I dig deeper into X509Chain status it says
RevocationStatusUnknown unable to get certificate CRL
Up until now I've been ignoring this error, but I'd rather have the underlying problem fixed and I don't know what exactly I'm missing. Thanks.
If you are running your .NET application on Mono, there's a Mono FAQ that explains how to import root certificates into your certificate store: https://www.mono-project.com/docs/faq/security/
If you are using .NET Core CLR, you might find this answer helpful: Trusted Root Certificates in DotNet Core on Linux (RHEL 7.1)
I need to know the proper way to setup the MobileFirst Application Center to use SSL (due to the requirement for supporting iOS v9 devices).
MobileFirst is v7.1 running on WebSphere Application Server ND v8.5.5.0.
I have reviewed the instructions from here:
https://www.ibm.com/support/knowledgecenter/SSHS8R_7.1.0/com.ibm.worklight.installconfig.doc/appcenter/c_ac_ssl_config.html
I was then navigated to here:
https://www.ibm.com/support/knowledgecenter/SSHS8R_7.1.0/com.ibm.worklight.installconfig.doc/admin/c_ssl_config.html%23c_ssl_config?lang=en
As advised, I created a self-signed certificate, like so:
openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout privateKey.key -out certificate.crt -reqexts v3_req -extensions v3_ca
The above two pages imply that all I need to do is to create a self-signed CA certificate and upload it to the AppCenter console.
Whilst this will allow the App Center Client to distribute the certificate for installation on the devices, I do not see how the "server-side" should be setup?
On the first link above, there is a sub-link to 'setting up SSL for WAS Full Profile', but, those instructions are for using a "proper" certificate and not a self-signed CA certificate.
Am I missing something obvious here? Creating the self-signed CA certificate and distributing it to the client device seems like only 1/2 a job. I don't understand how, when using the Application Center Client, I enter the [user/pwd hostname/9443/applicationcenter] details and it will connect and authenticate using SSL to the Application Center.
Are there any straight forward instructions (or advice) that explain what the proper process is to setup Application Center for SSL to allow for iOS v9 devices to securely connect to the Application Center?
WAS does not care if the certificate you are using is self-signed or not. So the instructions in the first link you referenced are still applicable (except that, if you already have this certificate, you don't need to create a certificate signing request, so step #1 in the doc isn't necessary).
There is a blog post here that discusses how to configure your server to work with iOS 9 App Transport Security. This is not specific to Application Center.
I have a certificate generated by a CA. The CSR for this certificate was raised by my IT team using Microsoft IIS Server. I would like to install this certificate in my JBOSS EAP 6.3 server. Can some one please help me with the steps?
