WebFeb 14, 2024 · Time to read: 6 minutes. A hashing algorithm is a mathematical function that garbles data and makes it unreadable. Hashing algorithms are one-way programs, so the text can’t be unscrambled and decoded by anyone else. And that’s the point. Hashing protects data at rest, so even if someone gains access to your server, the items stored … 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
