Choosing the Appropriate Certificate Installation Method for Your Network Depending on your network environment, you can use any of the following methods to install certificates and their public-private key pairs. The methods differ in terms of simplicity and security. The simplest method is also the least secure, while the most secure method is slightly more complex to use. • Self-signed certificate-The easiest method to use because a CA server is not required. The switch generates and signs the certificate itself. This method is the simplest but is also the least secure, because the certificate is not validated (signed) by a CA. • PKCS #12 object file certificate-More secure than using self-signed certificates, but slightly less secure than using a Certificate Signing Request (CSR), because the private key is distributed in a file from the CA instead of generated by the switch itself. The PKCS #12 object file is more complex to deal with than self-signed certificates. However, you can use Web View or the CLI to distribute this certificate. The other two methods can be performed only using the CLI. • Certificate Signing Request (CSR)-The most secure method, because the switch's public and private keys are created on the switch itself, while the certificate comes from a trusted source (CA). This method requires generating the key pair, creating a CSR and sending it to the CA, cutting and pasting the certificate signed by the CA into the CLI, and then cutting and pasting the CA's own certificate into the CLI. The table below lists the steps required for each method and refers you to appropriate instructions. Certificate Installation Method Self-signed certificate PKCS #12 object file certificate Certificate Signing Request (CSR) certificate Steps Required Instructions 1. Generate a public-private key pair on • "Creating Public-Private Key Pairs" the switch. • "Generating Self-Signed Certificates" 2. Generate a self-signed certificate on the switch. 1. Copy a PKCS #12 object file (public- "Installing a Key Pair and Certificate private key pair, server certificate, and from a PKCS #12 Object File" CA certificate) from a CA onto the switch. 2. Enter the one-time password to unlock the file. 3. Unpack the file into the switch's certificate and key store. 1. Generate a public-private key pair on • "Creating Public-Private Key Pairs" the switch. • "Creating a CSR and Installing a 2. Generate a CSR on the switch as a Certificate from a PKCS #7 Object PKCS #10 object file. File" 3. Give the CSR to a CA and receive a • "Installing a CA's Own Certificate" signed certificate (a PEM-encoded PKCS #7 object file). 4. Paste the PEM-encoded file into the CLI to store the certificate on the switch. 5. Obtain and install the CA's own certificate. D-Link DWS-1008 User Manual 261
