Generate Client Cert And Key

You need to generate your own self-signed certificate or request a certificate to a Trusted Authority. After this you will get the.key (the private key of the certificate) and.crt (the public part of the certificate) To create a self signed certificate follow this link How to create a self-signed certificate with openssl? You will need openssl. Mar 29, 2016  In the same way we extracted the server’s public key, we can extract the client’s public key with the following command. This generates a file called client.cert containing the public certificate from the client.jks keystore. Apr 09, 2020 Step 3: Generate CA x509 certificate file using the CA key. You can define the validity of certificate in days. Here we have mentioned 1825 days. The following command will prompt for the cert details like common name, location, country, etc. After you generate your Client Certificate, we recommend that you open up the browser(s) that you intend to use to log into the DigiCert account and verify that the certificate is installed in the appropriate Certificate. Oct 21, 2019  I'am trying to connect to a MariaDB instance hosted on AWS RDS, my application requires ca.pem, client-cert.pem and client-key.pem, and Amazon only gives me a rds-combined-ca-bundle.pem. I don't know much about TLS. I need to generate those files? When I follow the Create the Client Key and CSR it outputs: CA certificate and CA private key do.

When creating certificates on the BIG-IP ® system, you can create a certificate with a key type of ECDSA (Elliptic Curve Digital Signature Algorithm). An ECDSA key is based on Elliptic Curve Cryptography (ECC), and provides better security and performance with significantly shorter key lengths. For example, an RSA key size of 2048 bits is equivalent to an ECC key size of only 224 bits.

The Application Gateway v2 SKU introduces the use of Trusted Root Certificates to allow backend servers. This removes authentication certificates that were required in the v1 SKU. The root certificate is a Base-64 encoded X.509(.CER) format root certificate from the backend certificate server. It identifies the root certificate authority (CA) that issued the server certificate and the server certificate is then used for the TLS/SSL communication.

Application Gateway trusts your website's certificate by default if it's signed by a well-known CA (for example, GoDaddy or DigiCert). You don't need to explicitly upload the root certificate in that case. For more information, see Overview of TLS termination and end to end TLS with Application Gateway. However, if you have a dev/test environment and don't want to purchase a verified CA signed certificate, you can create your own custom CA and create a self-signed certificate with it.

Note

Self-signed certificates are not trusted by default and they can be difficult to maintain. Also, they may use outdated hash and cipher suites that may not be strong. For better security, purchase a certificate signed by a well-known certificate authority.

In this article, you will learn how to:

• Create your own custom Certificate Authority
• Create a self-signed certificate signed by your custom CA
• Upload a self-signed root certificate to an Application Gateway to authenticate the backend server

Prerequisites

• OpenSSL on a computer running Windows or Linux

  While there could be other tools available for certificate management, this tutorial uses OpenSSL. You can find OpenSSL bundled with many Linux distributions, such as Ubuntu.

• A web server/ea-games-cd-key-generator-2015.html.

  For example, Apache, IIS, or NGINX to test the certificates.

• An Application Gateway v2 SKU

  If you don't have an existing application gateway, see Quickstart: Direct web traffic with Azure Application Gateway - Azure portal.

Create a root CA certificate

Create your root CA certificate using OpenSSL.

Create the root key

1. Sign in to your computer where OpenSSL is installed and run the following command. This creates a password protected key.

2. At the prompt, type a strong password. For example, at least nine characters, using upper case, lower case, numbers, and symbols.

Create a Root Certificate and self-sign it

1. Use the following commands to generate the csr and the certificate.

   The previous commands create the root certificate. You'll use this to sign your server certificate.

2. When prompted, type the password for the root key, and the organizational information for the custom CA such as Country, State, Org, OU, and the fully qualified domain name (this is the domain of the issuer).

Create a server certificate

Next, you'll create a server certificate using OpenSSL.

Create the certificate's key

Use the following command to generate the key for the server certificate.

Create the CSR (Certificate Signing Request)

The CSR is a public key that is given to a CA when requesting a certificate. The CA issues the certificate for this specific request.

Note

The CN (Common Name) for the server certificate must be different from the issuer's domain. For example, in this case, the CN for the issuer is www.contoso.com and the server certificate's CN is www.fabrikam.com.

1. Use the following command to generate the CSR:

2. When prompted, type the password for the root key, and the organizational information for the custom CA: Country, State, Org, OU, and the fully qualified domain name. This is the domain of the website and it should be different from the issuer.

Generate the certificate with the CSR and the key and sign it with the CA's root key

1. Use the following command to create the certificate:

Verify the newly created certificate

1. Use the following command to print the output of the CRT file and verify its content:

2. Verify the files in your directory, and ensure you have the following files:

   • contoso.crt
   • contoso.key
   • fabrikam.crt
   • fabrikam.key

Configure the certificate in your web server's TLS settings

In your web server, configure TLS using the fabrikam.crt and fabrikam.key files. If your web server can't take two files, you can combine them to a single .pem or .pfx file using OpenSSL commands.

IIS

For instructions on how to import certificate and upload them as server certificate on IIS, see HOW TO: Install Imported Certificates on a Web Server in Windows Server 2003.

For TLS binding instructions, see How to Set Up SSL on IIS 7.

Apache

The following configuration is an example virtual host configured for SSL in Apache:

NGINX

The following configuration is an example NGINX server block with TLS configuration:

Access the server to verify the configuration

1. Add the root certificate to your machine's trusted root store. When you access the website, ensure the entire certificate chain is seen in the browser.

   Note

   It's assumed that DNS has been configured to point the web server name (in this example, www.fabrikam.com) to your web server's IP address. If not, you can edit the hosts file to resolve the name.

2. Browse to your website, and click the lock icon on your browser's address box to verify the site and certificate information.

Verify the configuration with OpenSSL

Or, you can use OpenSSL to verify the certificate.

Upload the root certificate to Application Gateway's HTTP Settings

To upload the certificate in Application Gateway, you must export the .crt certificate into a .cer format Base-64 encoded. Since .crt already contains the public key in the base-64 encoded format, just rename the file extension from .crt to .cer.

Azure portal

To upload the trusted root certificate from the portal, select the HTTP Settings and choose the HTTPS protocol.

Azure PowerShell

Or, you can use Azure CLI or Azure PowerShell to upload the root certificate. The following code is an Azure PowerShell sample.

Note

The following sample adds a trusted root certificate to the application gateway, creates a new HTTP setting and adds a new rule, assuming the backend pool and the listener exist already.

Verify the application gateway backend health

1. Click the Backend Health view of your application gateway to check if the probe is healthy.
2. You should see that the Status is Healthy for the HTTPS probe.

Openssl Generate Client Certificate

This section describes how to use the openssl command to set up SSL certificate and key files for use by MySQL servers and clients. The first example shows a simplified procedure such as you might use from the command line. The second shows a script that contains more detail. The first two examples are intended for use on Unix and both use the openssl command that is part of OpenSSL. The third example describes how to set up SSL files on Windows.

There are easier alternatives to generating the files required for SSL than the procedure described here: Let the server autogenerate them or use the mysql_ssl_rsa_setup program. See Section 5.3.1, “Creating SSL and RSA Certificates and Keys using MySQL”.

Whatever method you use to generate the certificate and key files, the Common Name value used for the server and client certificates/keys must each differ from the Common Name value used for the CA certificate. Otherwise, the certificate and key files will not work for servers compiled using OpenSSL. A typical error in this case is:

The following example shows a set of commands to create MySQL server and client certificate and key files. You will need to respond to several prompts by the openssl commands. To generate test files, you can press Enter to all prompts. To generate files for production use, you should provide nonempty responses.

After generating the certificates, verify them:

You should see a response like this:

To see the contents of a certificate (for example, to check the range of dates over which a certificate is valid), invoke openssl like this:

Now you have a set of files that can be used as follows:

• ca.pem: Use this to set the ssl_ca system variable on the server side and the --ssl-ca option on the client side. (The CA certificate, if used, must be the same on both sides.)

• server-cert.pem, server-key.pem: Use these to set the ssl_cert and ssl_key system variables on the server side.

• client-cert.pem, client-key.pem: Use these as the arguments to the --ssl-cert and --ssl-key options on the client side.

For additional usage instructions, see Section 5.1, “Configuring MySQL to Use Encrypted Connections”.

Here is an example script that shows how to set up SSL certificate and key files for MySQL. After executing the script, use the files for SSL connections as described in Section 5.1, “Configuring MySQL to Use Encrypted Connections”.

Generate Client Cert And Key Code

Download OpenSSL for Windows if it is not installed on your system. An overview of available packages can be seen here:

Choose the Win32 OpenSSL Light or Win64 OpenSSL Light package, depending on your architecture (32-bit or 64-bit). The default installation location will be C:OpenSSL-Win32 or C:OpenSSL-Win64, depending on which package you downloaded. The following instructions assume a default location of C:OpenSSL-Win32. Modify this as necessary if you are using the 64-bit package.

If a message occurs during setup indicating '..critical component is missing: Microsoft Visual C++ 2008 Redistributables', cancel the setup and download one of the following packages as well, again depending on your architecture (32-bit or 64-bit):

• Visual C++ 2008 Redistributables (x86), available at:

• Visual C++ 2008 Redistributables (x64), available at:

After installing the additional package, restart the OpenSSL setup procedure.

During installation, leave the default C:OpenSSL-Win32 as the install path, and also leave the default option 'Copy OpenSSL DLL files to the Windows system directory' selected.

When the installation has finished, add C:OpenSSL-Win32bin to the Windows System Path variable of your server (depending on your version of Windows, the following path-setting instructions might differ slightly):

1. On the Windows desktop, right-click the My Computer icon, and select Properties.

2. Select the Advanced tab from the System Properties menu that appears, and click the button.

3. Under System Variables, select Path, then click the button. The Edit System Variable dialogue should appear.

4. Add ';C:OpenSSL-Win32bin' to the end (notice the semicolon).

5. Press OK 3 times.

6. Check that OpenSSL was correctly integrated into the Path variable by opening a new command console (Start>Run>cmd.exe) and verifying that OpenSSL is available:

After OpenSSL has been installed, use instructions similar to those from Example 1 (shown earlier in this section), with the following changes:

• Change the following Unix commands:

  On Windows, use these commands instead:

• When a ' character is shown at the end of a command line, this ' character must be removed and the command lines entered all on a single line.

After generating the certificate and key files, to use them for SSL connections, see Section 5.1, “Configuring MySQL to Use Encrypted Connections”.
