Hi,
I hope somebody can point me in the right direction. I have written a
short
assembly language routine to
perform Xtea encryption, but unfortunately it doesn't give the output
expected by the "Test Vectors for
TEA and XTEA". This may be due to my program being rubbish, or because I
have misunderstood the
vectors.
What I need then is a a simple 64 bit of unencrypted data, the resulting
encrypted string, the 128 bit key
used for the encryption and the number of Feistel rounds used to encrypt
it.
Various libraries have xtea source in them. LibTomCrypt (libtom.org)
is one of them.
Though, may I ask why you're using XTEA as opposed to something like
AES?

I am using a really really tiny microcontroller with next to no program
space
or RAM. I could use any of the available programs in Delphi, C++, Java etc.,
to make a test file on my PC, but that would entail getting a compiler,
learning to use it etc.. As a first step I only want to confirm or deny that
the
program is working correctly.
