This article describes how to configure a more secure option: Other articles describe other tools for creating a CA-signed certificate: Linux administrators typically use OpenSSL. Your on-premises Code42 authority server is no exception. A Code42 server that is configured to use a signed certificate , strict TLS validation , and strict security headers protects server communications with browsers, your Code42 apps, and other servers.

By default, your authority server uses a self-signed certificate and TLS. That provides for encrypting client-server traffic. Adding a CA-signed certificate provides further security by confirming your server's identity to clients. Configuring Code42 servers and apps to use strict TLS validation further ensures the security of client-server connections.

The keystore contains: You do not need any further access to the authority server's host machine. From the action menu, choose Dump Database. Install KeyStore Explorer if it is not already installed. If you intend to import a certificate with an encryption key that exceeds the Java import limits on cryptographic algorithms , you must first configure your enterprise server to accept longer encryption keys.

Considerations For multi-server Code42 environments, we recommend applying this process to all Code42 servers. This article assumes you are familiar with the following: Assistance with creating your keystore Assistance with the handling of a certificate signing request CSR or creating your keystore is beyond the scope of Customer Champions.

CA-Signed Certificate: A certificate authority CA electronically signs a certificate to affirm that a public key belongs to the owner named in the certificate. Someone receiving a signed certificate can verify that the signature does belong to the CA, and determine whether anyone tampered with the certificate after the CA signed it. Certificate Chain: One signed certificate affirms that the attached public key belongs to its owner.

A second signed certificate affirms the trustworthiness of the first signer, a third affirms the second, and so on. The top of the chain is a self-signed but widely trusted root certificate. Root Certificate: A certificate trusted to end a certificate chain. Operating systems and web browsers typically have a built-in set of trusted root certificates.

When your server sends a chain of certificates and one of them matches one of a browser's trusted root certificates, then the browser trusts your server. When the browser encrypts data with your public key, the browser is assured that only your server can read it. Self-Signed Certificate: A file that contains a public key and identifies who owns that key and its corresponding private key.

A unique string of characters that provides essential input to a mathematical process for encrypting data. Key Pair: A public encryption key and a private encryption key, in a matched set. A file that holds a combination of keys and certificates. File formats: Java Keystore: A binary file format for use by Java applications like the Code42 server.

Typical file names are. A binary file format typically associated with Windows systems. PEM files are common on Linux systems and Apache. To identify a PEM file, open it with a console or text editor. Public Key: Allows a sender client or server to encrypt a message for a specific recipient server or client.

When your server sends a browser its public key, the browser can encrypt messages that only your server can read, because only your server has the matching private key. If you have an existing private key and corresponding X. You can also start from scratch, creating new key materials as needed.

The steps are different, depending on what existing key materials you have: Most browsers now distrust such certificates. Option 1: Build a keystore without existing key materials Keypass and storepass parameters You must use the same password for the keystore and the private key. You can use any string you want for these parameters, but they must both be set to the same value.

Follow the steps below if you have no private keys or certificates from a CA and need to create them from scratch. Step 1: Create a keystore, key pair, and certificate Start KeyStore Explorer.

Choose Create a new KeyStore. Click OK. In Generate Key Pair, choose the following algorithm selection options:

Configuring the switch for SSL operation

Step 2: Now we create a server key pair that will be used by the broker Command is: Now we create a certificate request. When filling out the form the common name is important and is usually the domain name of the server. You could use the IP address or Full domain name.

You must use the same name when configuring the client connection. Command is: Now we use the CA key to verify and sign the server certificate. This creates the server. The above steps created various files. This is what the directory looks like now: This file is used when creating new server or client certificates.

Step 7: Copy the files ca. I have used a folder called certs. Step 8: Step 9: Edit the mosquitto. The ca path is not used as I told it the file location instead. On my Linux install the entire TLS section of the mosquitto. Here is the mosquitto.

Edit the client to tell it to use TLS and give it the path of the CA certificate file that you copied over. Although there are several parameters that you can pass the only one you must give is the CA file as shown below. The python client will default to TLSv1. However to change it to TLSv1. Problems I Encountered and Notes While creating and working through these procedures i encountered the following problems Error when connecting due to the common name on the server certificate not matching.

Not using the correct name for the broker. I used the IP address and not the name that I entered into the certificate. Authentication errors as I had previously configured my broker to require passwords. When the browser encrypts data with your public key, the browser is assured that only your server can read it.
