Cisco provides a Mini Certificate Generator for the generation of mini certificates
and private keys. Partners can download the Mini Certificate Generator by going
to Cisco Partner Central, Voice & Conferencing page, Technical Resources section.

NOTE The partner sites require a logon.
The Mini Certificate Generator uses the following syntax:

Where:
• ca-key is a text file with the base64 encoded 1024-bit CA private/public key
pairs for signing/verifying the MC, such as the following:

maximum length is 16 characters.
• expire-date is the expiration date of the MC, such as “00:00:00 1/1/34”
(34=2034). Internally the date is encoded as a fixed 12B string: 000000010134
