WebKeys should only be used for a limited period of time, known as a cryptoperiod. This practice limits the time and data available for cryptanalysis, limits the exposure if a single key is compromised, and enables prompt adoption of new algorithms when appropriate. The appropriate length for a cryptoperiod depends on the strength of the
