# In a first version I wrote a kernel that followed the original sqlcipher scheme which uses a MAC to verify the integrity (and therefore we knew we had guessed the correct password).
# But it turns out it's much easier to exploit the sqlite header format, which guarantees 20 zero bytes starting from offset 72.
# See: https://www.sqlite.org/fileformat.html
# The advantage is the user doesn't need to guess the MAC hash type and/or pagesize (in case it they customized).
# The user still needs to know the KDF hash type and iteration count, but they sqlcipher v3 and v4 come with a default for these.
# We'll check only 12 of 16 bytes from the encrypted block as an optimization so we only need to decrypt one block.
# Another optimization is that since the scheme uses CBC we do not need to find the correct position of the IV.
# This position is depending on the pagesize and the KDF hash type (which could be customized).
# As an alternative, or in case the sqlite header changes, we could also use entropy test.
