Is there a way to map/translate a pattern-lock to a numeric PIN?

I just encrypted my Moto X (Gen 1) (KitKat 4.4.4) using the default encryption option from the Settings > Security menu. After the encryption process finished, it asks me, "Type password to decrypt storage". Only there's one problem: it never asked me for a password. It seems I'm [not the only one](http://forums.androidcentral.com/moto-x-2013/388088-encryption-gone-wrong-no-password.html) who experienced this. I've tried my Google password like 3 times, and, like that other poor soul, I haven't been able to find a way to map my pattern-lock to a PIN, which might be what Android used for the encryption. For the mappings, I have tried a standard phone dial pad: 1 2 3 4 5 6 7 8 9 and a standard keyboard numpad: 7 8 9 4 5 6 1 2 3 and a wild guess based on how a developer might do it: 0 1 2 3 4 5 6 7 8 Presumably, though not necessarily, Android stores that pattern as a string or number somehow. Given a certain unlock pattern, how do I find the string or number that represents that pattern? **** To the moderators: I'm fine deleting this question if it's not on-topic. I think the question would have been on-topic if the answer fixed my problem. I'm not sure how you guys see that.
