I've read that habits are stored in the memory in different ways than regular memories, and habits are more durable to incidents such as amnesia. (citation needed) Perhaps by practicing typing the encryption key day after day, you could record it in muscle memory and it would be amnesia proof. Or perhaps you could invent a unique hand-dance (think hand-jive) and practice it daily, and you could write a program that could decode the sequence into a key.
