Because I used same tool to create test-vectors which I had previously used to create AES/Camellia/Serpent/Twofish test-vectors. So, I must have forgotten to change 16-byte IV generation to 8 bytes and thus those testcases in crypto/testmgr.h have wrong length. The extra trailing 8 bytes are not used and can be removed. -Jussi > > Thank you. :) >
