I have a certificate chain comprised of the root certificate, intermediate certificate, and server certificate. The root certificate is installed on my local machine. The intermediate certificate and server certificate are installed on my tomcat server.
I am unable to find instructions anywhere on how to create an intermediate certificate such that it is standards compliant. This is the error that I am receiving:
Here are the details of the "inter" certificate, according to KeyStore Explorer:

I can't connect with my Tableau Server from Tableau Desktop because it shows me that error: SSL certificate is not valid. I'm searching for a solution, but I'm only reading how to change the certificate with another, beacause I do not have any other certificate.
My question goes before that: how can I get a certificate? where I can get it from?
This is the guide from Tableau I use whenever I need to setup SSL for my servers. It includes obtaining an SSL Certificate from a certificate authority Steps for SSL Cert
To configure Tableau Server to use SSL, you must have an SSL certificate. To obtain the SSL certificate, complete the steps:
Set the OpenSSL configuration environment variable (optional)
Generate a key file
Create a Certificate Signing Request (CSR)
Send the CSR to a certificate authority (CA) to obtain an SSL certificate
Use the key and certificate to configure Tableau Server to use SSL
I have the company CA signed certificate, intermediate and server certificate in the identity store ( .jks) but still the browser says , cannot be verified by a trusted authority error. Using weblogic -10.3.1 from the weblogic logs i also notice this -
Invalid/unknown SSL header was received from peer x.y.z.12 during SSL handshake
But when I install the root and intermediate certificates into certmgr.msc then when i access the url again in a new window it has no error on the browser and also no error log in the weblogic server.
What could be wrong ?
Global CA's have their root and intermediates recognised by all the modern browsers. However when browser encounter s a certificate whose intermediate and roots aka chain certificates & ca certificates are not a part of its trust store so it fails to chain the leaf certificate to its issuer. So in order to mitigate thi, the roots and intermediates of the company ca must be added so that the browser can verify the complete chain.
Agreed .but thats how the trust works. The company issues ca certificate is known only to your organization but browsers are accessed globally and if you want make the certificate trusted in all the browsers then either you switch to public ca issued certificates or get your root certificate cross signed by a global ca root.
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'm trying to add TLS to a node application connecting to RethinkDB database. I've setup the RethinkDB to use --driver-tls* parameter.
The strange thing to me is that on the client side I need to provide the CA certificate use to sign the certificates used by the server.
Is that root CA certificate can be self-signed or does it have to be signed with a trusted root CA itself?
I have simple app runing on jboss server. I have following certificates:
Self Signed Root CA, intermediate CA 1 (signed by root), intermediate CA 2 (signed by root), .pfx certificate for my webpage. I had created a keystore with my .pfx certificate and added it to correct folder in jboss and modified http connection in server.xml file. Anyway when i acccess webpage i see warning triangle that CA is unknown. My question is how shoudl i configure jboss to make warning disappear? Soudl i add it to the trustore? or only way is to add it to Windows/web browser root store?
The browser's warning page appears because the self-signed certificate is not locally trusted. There is nothing that can be done on the server end to hide this warning.
You must put the certificate in the browser's trust store, or get a certificate from a certificate authority that is already trusted.
