This topic explains how to generate and install RSA key pairs and generate Certificate Signing Request (CSR) on the

Spacevars
0 series4

systems. The certificate request is then sent to a CA, and the issued certificate is then installed on the SBC. This feature simplifies the certificates and keys managing process, and also provides more security than previous methods since the private key never leaves the SBC system. For feature description, see Certificate Management.

Note During this procedure, the CSR contents display in an alert message. The simplest method to copy this data is to use the mouse to click-and-drag the contents, and then copy-paste elsewhere. Sonus Ribbon recommends using Firefox Web browser to perform this procedure since it supports this simple copy-paste method.

Generate RSA Key Pairs and CSRs Using EMA

1. Login to EMA GUI.
   
   

2. Create a configuration object to hold a locally generated RSA key pair.

   1. On the main screen, go to one of the following locations:

      • All > System > Security > PKI > Certificate

      • Configuration > Security Configuration > PKI > Certificate
        The Certificate screen is displayed.

   2. Click New Certificate.

   3. The following fields are displayed:

       

      Parameter	Description
      Name	Specifies the name of the certificate.
      State	Leave as Disabled (default value).
      File Name	NA
      Pass Phrase	NA
      Type	From the drop-down list select local-internal.

   4. Click Save to save the changes. The new Certificate is displayed at the bottom of the original Certificate in the Certificate List panel.
      
      

3. Generate Key pair and CSR (certificate signing request) for submission to a Certificate Authority (CA):
   
   

   1. Select newly-created certificate from the list. The Certificate screen refreshes with the newly-created certificate object, and now displays the Edit Selected Certificate and Certification Commands options in the lower pane.

   2. Select Generate CSR option from the Certificate Commands drop-down menu, and click Select. The SBC Generate CSR Command dialog is displayed.

   3. The following are the Certificate parameters:

       

      Parameter	Description
      key Size	The size in bits of the key pair to generate the private key. keySize1k – 1024 bits keySize2k (default) – 2048 bits Note icon false Note Sonus Ribbon recommends using the 2048 bit key size wherever possible since it provides greater security strength.
      Csr Subscription	<csr subject name> The name of the CSR subject using the following format. Note icon false Note At least one of the following keys must be specified in the csr subject name. /C=<xx>/ST=<xx>/L=<string>/O=<string>/CN=<string> Where: C = 2-digit country abbreviation ST = 2-digit state or province abbreviation L = Locality name O = Organization name CN = Common Name Example: /C=US/ST=MA/L=Westford/O=Sonus Ribbon Inc./CN=www.sonusnetribbonnet.com
      Subject Alternative Dns Name	Specifies the names of the alternative DNS subjects. Multiple alternative names can be specified using "," (comma) as a separator. For example: "nj.sonusnetribbonnet.com, in.sonusnetribbonnet.com, uk.sonusnetribbonnet.com, ca.sonusnetribbonnet.com, tx.sonusnetribbonnet.com" Note icon false Note This field is available from 4.0.2 release.

   4. Make the required changes to the required fields and click generateCSR. The CSR displays in an alert message similar to below:

4. Copy-paste CSR content. Two methods are described below:
   
   
   1. Firefox: Click-and-drag your mouse pointer to highlight the text, then do a Ctrl+C, Ctrl+V to copy and paste contents elsewhere.
      
      

   2. Internet Explorer: Click the alert message, and then perform a Ctrl-A to select it, a Ctrl-C to copy contents, and a Ctrl-V to paste contents elsewhere.

      Note
      icon false
      Note Using IE method may result in copying additional web page data unrelated to CSR content within the CSR header and footer. If this occurs, be sure to remove the irrelevant content.

5. Contact CA to request a certificate using the generated CSR results.

See CSR Subject Field Syntax for descriptions of the fields.

Generate RSA Key Pairs and CSRs Using CLI

1. Login to the SBC CLI, and switch to Configure mode.
   
   

2. Create a configuration object to hold a locally generated RSA key pair:

   Code Block
   % set system security pki certificate <certName> type local-internal

3. Generate Key pair and CSR for submission to a Certificate Authority (CA):

   Code Block
   % request system security pki certificate <certName created from step 2> generateCSR csrSub <csrSub> keySize <keySize>

4. Contact CA to request certificate using the generated CSR.
   
   

5. Once CA issues the certificate, place the certificate in SBC at /opt/sonus/external/<PEM_filename> and install the certificate using the command:

   Code Block
   % set system security pki certificate <certName> filename <PEM_filename> state enabled

Import Certificate Using EMA

Use one of the following methods to import certificate:

• Use importCert Command
• Copy certificate to /opt/sonus/external

4. Copy and paste the returned certificate content from the CA to the Cert Content field.
   
   

5. Click importCert to import the certificate content to the SBC.

Copy certificate to /opt/sonus/external:

1. Once CA issues the certificate, place the certificate in the SBC directory: /opt/sonus/external/<PEM_filename>



2. On the main screen, go to one of the following locations:

   • All > System > Security > PKI > Certificate

   • Configuration > Security Configuration > PKI > Certificate
