I want/need to install an TLS (1.2 or higher) Certificate (remember to SSL).
I have probably the Certificate (apt12345678.p12).
How could i copy the Certificate in my Apps Script?
Docu says: "The connection to the authorization server is established using Mutual SSL."

I have a problem configuring SSL certificates between my client and my Server.
My client, is a frontend application written in Angular, installed on a Web Hosting called V-Hosting which provides cPanel and through which it is possible to install a free Let's Encrypt SSL certificate (with auto renewal certificate).
Therefore, a user's connection to the website is protected by the certificate made available by CPanel - Let's Encrypt.
Instead the Server, a Backend application written in Java, is on a Contabo VPS (Virtual Private Server).
On this virtual server there is Windows OS and I have Jboss installed, where my .ear package is installed.
My problem is that I can't figure out how to configure an SSL certificate so that client and server can communicate over https, as now my domain https://example.com/ can't communicate with my server on JBoss http://IP_SERVER:8080/rest/api as the Server has no certificate.
So, client has a certificate (https) but server not (http) and they can't communicate each other without a certificate on Server.
How can I make the Client and Server communicate in HTTPS?
I tried to install Keystore Explorer on my VPS and generate a keystore to install on jboss but it's not the best solution because then I would have a Let's encrypt certificate on the client and one self signed by me on the server.
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 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 have purchased & installed Godaddy SSL certificate. When I access the site using Chrome 24ver the https padlock shows
1) encrypted with 128-bit
2) uses TLS 1.0
3) encrypted using RC4_128 with SHA1
However I read that RC4 is not safe anymore. So my question is
1) How reliable is https connection with mentioned specs
2) How do I get AES_CBC certificate?
3) I was being told that since the server is windows hosted it cannot be upgraded to 256-bit. Is it true? If not then what should I do?
Thanks
You are mixing things up. There is no RC4 certificate or AES_CBC certificate.
You certificate is signed by a certificate authority that issued it. In your case it is Godaddy. Look for Signature Algorithm property when you open details of the certificate (i.e. doubleclick on certificate file). There will probably be something like sha1RSA or sha256RSA or something similar.
RC4 is a cipher that is negotiated when establishing SSL conection with server. It depends on both parties (client and server) witch algorithm they will use. Read more here. You can set up IIS to allow or disallow these ciphers.
am new to LDAP / Active Directory environment.
am trying to connect with LDAP / Active Directory using SSL support.
to connect LDAP/Active Directory, SSL certificate is required to establish the connection.
I have been googling, and most of the result is to "create certificate using Microsoft CA (certificate authority)". Is this is only way to generate certificate for LDAP/Active Directory?
How can i get SSL Certificate for LDAP / Active Directory?
Is there any other way to get the SSL Certificate for LDAP/Active Directory?
The OpenSSL tool can be used to:
generate a new self-signed certificate
generate a certificate request
retrieve an existing certificate from an LDAP server using LDAPS (but not StartTLS as of OpenSSL 0.9.8)
OpenSSL is available via the console on Mac OS and most Linux distributions.
You can get OpenSSL for Windows here:
OpenSSL Distributions
The Mac Keychain Access application can also be used to generate certificates.
LDAP client code that requires a secure connection should connect to the port upon which the directory server listens for SSL connections, or connect to the port upon which the directory server listens for unsecure connections and promote the connection security using the StartTLS extended operation. The certificate to which you refer is the certificate used by the directory server.
