How to Add an SSL Certificate

  • Last updated on
You can create a self-signed certificate, or upload a trusted certificate.

You can upload a signed certificate in either PKCS #12 Token Format or PEM format.

Adding a PKCS #12 Token Format Certificate

Use the following steps to upload a signed certificate obtained from a trusted Certificate Authority (CA) in PKCS #12 Token Format.

  1. Log into the Barracuda Load Balancer ADC web interface, and go to the BASIC > Certificates page.
  2. In the Upload Certificate section, select the Certificate Type as PKCS12 Token.
  3. Set Allow Private Key Export to Yes to export the private key corresponding to the certificate.

    Certificates are downloaded in PKCS #12 format including both the private key and certificate. If Allow Private Key Export is set to No, the private key is locked and the certificate can be downloaded only in PEM format and the system configuration backup cannot be taken.

    Allow Private Key Export is valid for generated and imported certificates only.
  4. Enter an identifying name in the Certificate Name field.
  5. In the Certificate Password field, specify a password that will be used to generate the PKCS #12 token for the signed certificate to be uploaded.
  6. Click Browse next to the Signed Certificate field, and select the PKCS #12 format signed certificate file.

    When uploading a signed certificate as a PKCS #12 token, ensure that the file uses a .pfx extension; otherwise the file is treated as a PEM file.

    When uploading a certificate in .pfx format, verify that any intermediary certificates are bundled in the .pfx file.

  7. Click Upload to upload the certificate.

Adding a PEM Format Certificate

Use the following steps to upload a signed certificate obtained from a trusted CA in PEM Format.

  1. Log into the Barracuda Load Balancer ADC web interface, and go to the BASIC > Certificates page.
  2. In the Upload Certificate section, select the Certificate Type as PEM Certificate.
  3. Set Allow Private Key Export to Yes to export the private key corresponding to the certificate.

    Certificates are downloaded in PKCS #12 format including both the private key and certificate. If Allow Private Key Export is set to No, the private key is locked and the certificate can be download only in PEM format and the system configuration backup cannot be taken.

    Allow Private Key Export is valid for generated and imported certificates only.
  4. If the certificate signing request (CSR) for this certificate was generated on the Barracuda Load Balancer ADC, set Assign the associated key to Yes, otherwise, select No, and upload the private key in the Certificate Key field.
  5. Enter an identifying name in the Certificate Name field.
  6. If the Assign the associated key field is set to No, click Browse next to the Certificate Key field to select the corresponding private key for the signed certificate.

    The key must be unencrypted and in PEM format.

  7. Click Browse next to the Signed Certificate field, and select the PEM format signed certificate file.
  8. Click Browse next to the Intermediary Certificates field, and select the intermediary CA certificate. To add additional intermediary CA certificates, click the plus ( + ) button. 

  9. Click Upload to upload the certificate.

    If your certificate is signed by a trusted CA, upload the certificate in the following order:

    1 - Leaf Certificate
    2 - Intermediate Certificates
    3 - Root CA Certificate 

For additional information, go to the BASIC > Certificates page in the Barracuda Load Balancer ADC web interface, and click the Help button.
