GM 5 Byte Key Calculator

Feed the captured security seed and algorithm ID to derive the 5-byte response ForgePoint expects. The tool mirrors the exact crypto path our back-end uses, so what you compute here will work in the garage.

Seed Options

Paste your captured seed, tweak the algo, and optionally drop in a custom password blob.

Advanced Options

Calculated Key

Run the calculator to see the 5-byte MAC, AES key, and iteration count instantly.

Find Algorithm

Already know the response key? Enter it with the exact seed to discover which algorithm byte produced it.

Run a lookup to list every algorithm byte that converts the seed into that exact key.
