Arg... A typo was holding things up...
The original code used the following in UncheckedSetKey, which is where
ciphers are keyed:
m_tweak[2] = m_tweak[0] + m_tweak[1];
The correct code is:
m_tweak[2] = m_tweak[0] ^ m_tweak[1];
We also needed a helper function for PutDecodedDatumInto. The test vectors
are little-endian, so they don't copy/paste into a text file.
I'm going to add some test vectors and check-in the change.
