How do I change the default SSL (Secure Socket Layer) certificate for the System Web Server and the Application Web Server that ships with LabVIEW?


Complete the following steps to change the SSL certificate for the System Web Server and Application Web Server:

1. Navigate to localhost:3582 to access the NI Web-based Configuration & Monitoring Utility. Note: For LabVIEW versions prior to 2013, navigate to localhost:3580.
2. Click the Web Server Configuration icon on the left navigation panel.

3.Click the Web Servers tab.
4. Select the SSL (HTTPS) Enabled checkbox and click the Apply button. Note: You may have to restart your computer before the change takes effect.
5. Click the SSL Certificate Management tab.
6. Click the Generate a new certificate signing request button under the Open Certificate Signing Requests column.

7. Complete the fields on the New signing request dialog box. In the Common name field, enter the IP address of the local host or a fully qualified domain name that can be resolved by the Domain Name System. Each CSR contains a randomly generated 1024-bit RSA key and uses the signature algorithm "SHA1 with RSAEncryption". The following are the default values of each field (the Subject alt name follows a strict syntax which can be looked up in the link in the related link section):
Common nameNewSigningRequest
State or ProvinceTX
Organizational unit<Blank>
Subject alt name<Blank>

8. Select NewSigningRequest in the open Certificate Signing Requests listbox. Click Advanced and highlight the text between -----BEGIN CERTIFICATE REQUEST----- and -----END CERTIFICATE REQUEST-----.
9. Complete one of the following steps to sign the Certificate Signing Request (CSR):
  • Send the CSR to your IT department or PKI service provider to be signed by the certificate authority (CA).
  • Sign the CSR with a self-generated CA certificate using OpenSSL (a useful method for test or lab environments). Complete the following steps to sign the CSR with a self-generated CA certificate:
    1. Create a text file called mydevice.csr on your desktop.
    2. Paste the certificate request you copied in step 8 into mydevice.csr.
    3. Download and install a binary distribution of OpenSSL.
    4. Enter the following commands to generate an RSA self-signed certificate:
      1. openssl x509 -req -in mydevice.csr -out mydevice.crt -CA testcacert.pem - Cakey privkey.pem -Cacreateserial
      2. openssl genrsa -out privkey.pem 1024 
10. Click the Install Certificate button in the WIF and navigate to the CA certificate you obtained in step 9. Note: The CA certificate name must match the CSR name.
11. Click the Web Servers tab and select NewSigningCertificate from the Certificate File pull-down menu.
