Security Calculators
10 free security calculators in Networking. The first 4 have a full write-up: the method, a worked example and questions specific to that calculator.
- Brute Force TimeEstimate the time required to brute-force a password or key given attempt speed.
- Firewall Rule EstimatorEstimate the number of firewall rules needed to cover a matrix of sources, destinations and services.
- TLS OverheadCalculate the latency and bandwidth overhead introduced by TLS handshakes and encryption.
- VPN OverheadCalculate the effective throughput loss caused by VPN tunneling and encryption overhead.
- Encryption OverheadCalculate the bandwidth and latency overhead added by encrypting network traffic.
- Hash RateCalculate hashing throughput and time required to compute a given number of hashes.
- Key Length ComparisonCompare cryptographic key lengths across algorithms for equivalent security strength.
- Password EntropyCalculate password entropy in bits based on length and character set.
- Password StrengthEvaluate password strength and estimated crack time based on complexity.
- SSL Certificate ExpiryCalculate the days remaining until an SSL/TLS certificate expires.
