Thanks for the replies! The reason why I thought it would be cool to have
SHA1-HMAC included was I had thought SHA1 was included (in the crypt/
folder). However, now that I look at it again, it's actually SHA2, which
makes the whole request bad :( I'll try my hand at porting the code from
Busybox.

Thanks for the kind responses!
Kyle.
