Enable One-Way TLS with EJBCA and OpenSSL CMP using Command Line

Enabling One-Way TLS EJBCA OpenSSL CMP Command Line Application

In this article, we will discuss how to enable a one-way TLS connection using the EJBCA OpenSSL CMP (Certificate Management Protocol) command line application. We will cover the key concepts, applications, and significance of this process, as well as provide detailed instructions on how to authenticate the TLS server certificate presented by EJBCA using a truststore CMP certificate.

Key Concepts

One-way TLS, also known as SSL, is a cryptographic protocol used to establish a secure communication channel between a client and a server. In a one-way TLS connection, the server is authenticated to the client, but the client is not authenticated to the server. This is in contrast to mutual TLS, where both the client and the server are authenticated to each other.

The EJBCA OpenSSL CMP command line application is a tool used to manage and issue digital certificates and certificate revocation lists (CRLs) using the CMP protocol. CMP is a standard protocol used for certificate management and is defined in RFC 4210.

Applications

Enabling a one-way TLS connection using the EJBCA OpenSSL CMP command line application is useful in scenarios where only the server needs to be authenticated to the client. For example, in a web server environment, the server can be authenticated to the client using a one-way TLS connection to ensure that the communication between the client and the server is secure and encrypted.

Significance

Enabling a one-way TLS connection using the EJBCA OpenSSL CMP command line application is important for ensuring the security and confidentiality of communication between a client and a server. By using a one-way TLS connection, the client can be sure that the server it is communicating with is the intended server and not an imposter. Additionally, the communication between the client and the server is encrypted, which helps to protect the confidentiality of the data being transmitted.

Enabling One-Way TLS using EJBCA OpenSSL CMP Command Line Application

To enable a one-way TLS connection using the EJBCA OpenSSL CMP command line application, you will need to perform the following steps:

1. Generate a truststore CMP certificate using the EJBCA web interface.
2. Export the truststore CMP certificate to a file.
3. Use the EJBCA OpenSSL CMP command line application to authenticate the TLS server certificate presented by EJBCA using the truststore CMP certificate.

Step 1: Generate a Truststore CMP Certificate

To generate a truststore CMP certificate using the EJBCA web interface, follow these steps:

1. Log in to the EJBCA web interface.
2. Navigate to the "Certificates" section and click on "New Certificate."
3. Select "Truststore CMP Certificate" as the certificate type and fill in the required fields.
4. Click "Create" to generate the truststore CMP certificate.

Step 2: Export the Truststore CMP Certificate

To export the truststore CMP certificate to a file, follow these steps:

1. Log in to the EJBCA web interface.
2. Navigate to the "Certificates" section and click on the truststore CMP certificate you generated in Step 1.
3. Click on the "Download" button and select "PEM" as the format.
4. Save the truststore CMP certificate to a file.

Step 3: Authenticate the TLS Server Certificate

To authenticate the TLS server certificate presented by EJBCA using the truststore CMP certificate, follow these steps:

1. Open a command prompt and navigate to the directory where the EJBCA OpenSSL CMP command line application is installed.
2. Run the following command:

Where server.crt is the TLS server certificate presented by EJBCA and truststore.pem is the truststore CMP certificate you exported in Step 2.
