User's Manual   10. Configuring SSL/TLS Certificates 
10.5  Generating Private Keys for TLS Contexts 
You can let the device generate the private key for a TLS Context. The private key can be 
generated for CSR or self-signed certificates. 
  To generate a new private key for a TLS Context: 
1.  Open the TLS Contexts table (see ''Configuring TLS Certificate Contexts''  on page 
109). 
2.  In the table, select the required TLS Context index row, and then click the Change 
Certificates link located below the table; the Chnage Certificates page appears.  
3.  Scroll down to the Generate New Private Key and Self-signed Certificate group: 
Figure  10-6: Generate new private key and self-signed certificate Group 
 
4.  From the 'Private Key Size' drop-down list, select the desired private key size (in bits) 
for RSA public-key encryption for newly self-signed generated keys: 
•  512  
•  768 
•  1024 (default) 
•  2048 
•  4096 
5.  (Optional) In the 'Private key pass-phrase' field, enter a password (passphrase) to 
encrypt the private key file. If you don't want to encrypt the file, make the field blank. 
The default passphrase is "audc". The passphrase can be up to 32 characters. 
6.  Click  Generate Private-Key; a message appears requesting you to confirm key 
generation.
