The underlying weakness: Use of a Key Past its Expiration Date
The product uses a cryptographic key past its expiration date.
How developers prevent this class of flaw
- Adequate consideration should be put into the user interface in order to notify users previous to the key's expiration, to explain the importance of new key generation and to walk users through the process as painlessly as possible.
- Replace keys within a period of time proportional to their strength.
