GM 2 Byte Key Calculator

Feed any Global A security seed and algorithm byte to reproduce the same 2-byte key the module expects. You can also brute-force the entire table for a seed or reverse a response to learn which tables and algorithms create it.

Seed + Algorithm

Paste the captured seed, choose the table, set the algorithm byte, and the calculator reproduces the exact 2-byte response.

Security Table

Calculated Response

Run the calculator to see the 2-byte response and normalized inputs instantly.

Brute Force Table

Sweep every algorithm in the selected table for a given seed. Useful when the dial position is unknown.

Run the sweep to list every algorithm entry for this table.

Reverse Lookup

Know the response already? Pair it with the same seed and we will list each table+algorithm combo that yields it.

Submit a lookup to reveal every table+algorithm combo that recreates the response.
