Tools
Tools that show the arithmetic.
Each tool reads from the same keyed numbers file as the lessons, so a figure here always matches the lesson that explains it.
- TLS handshake byte calculatorKey exchange, signature algorithm and chain shape in; per-message bytes, segments, initcwnd warning and latency out. Every step shown.
- Algorithm comparatorPublic key, private key and signature or ciphertext sizes for 14 algorithms. Sort, filter, and compare two side by side.
- Mosca calculatorData shelf life plus migration time against the quantum timeline, with presets for bank data classes and the challenge each input attracts.
- Regulatory timelineSourced deadlines by jurisdiction with a countdown to the next binding date.
- Decision treeFrom use case to algorithm recommendation, with the reasoning path and caveats visible.
- Cost modelBank parameters in, a cost range out. Every assumption listed, editable and tagged ESTIMATED.
- Protocol and system impact matrixPlannedTwelve systems against PQC impact, with reasoning per cell and YAML export.
