It provides encryption, authentication, and message integrity services. SSL is widely usedfor secure communication to a web server, and also for wireless authentication.Certificate/Private key combinations can be obtained from an external Certificate Authority (CA)and uploaded into the unit. Self-signed certificates with associated private key can be generatedby the device server itself.Note: The blue text in the XML command strings of this chapter are to be replaced witha user-specified name.Create a New CredentialAfter creating a new credential, you can either establish your credential through Certificate andKey Generation or Upload Certificate.Bit Size Select the bit length of the new key: 512 768 1024Using a larger Bit Size takes more time to generate the key. Approximate times are: 1 second for a 512 bit RSA key 1 second for a 768 bit RSA key 1 second for a 1024 bit RSA key 2 seconds for a 512 bit DSA key 2 seconds for a 768 bit DSA key 20 seconds for a 1024 bit DSA keyNote: Some SSH clients require RSA host keys to be at least 1024 bits long. Thisdevice generates keys up to 2048 bits long.Submit (button) Click the Submit button after entering the information for the new key.SSH Settings Description
