On the Subject of Pigpen Cycles
Does this even count as a pigpen cipher anymore?
To encrypt:
For each letter:
- Look up its position in one of the 3x3 tables below. If your letter appears multiple times, pick any of them.
- Move clockwise around the outer edge of the 3x3 grid as many times as there are 45-degree rotations of the corresponding dial. If your letter is E or N, do nothing.
- If you moved an odd number of steps (aka odd number of 45-degree rotations), move to the same position of the other 3x3 table vertically in the big 2x2 grid. This also applies if your letter is E or N.
To decrypt:
Move counter-clockwise instead of clockwise.
