Description
The longer and more often a key is used, the more susceptible it is to loss or discovery. This weakens the assurance provided to a relying Party that the unique binding between a key and its named subscriber is valid. Therefore, it is important that certificates are periodically refreshed. This is in accordance with DoD requirement. Expired Certificate must not be in use.
