recommends. During each pass we will write a valid working header. Each pass will use the same master
key, and also the same header key, secondary key (XTS), etc., derived from the new password. The only

Issue 09/09/2006
This is an AES implementation that uses only 8-bit byte operations on the
cipher state (there are options to use 32-bit types if available).
The combination of mix columns and byte substitution used here is based on
that developed by Karl Malbrain. His contribution is acknowledged.
