How to Use This Calculator
  1. Enter the key length in bits and the encryption algorithm.
  2. Set the attacker computational power in operations per second.
  3. Input the attack duration in hours or days.
  4. Review the probability of a successful brute-force attack within the timeframe.
  5. Use the result to evaluate whether current key lengths meet security requirements.
