Block Sizes smaller than 512B

[seesharpsteve]

Is there anyway to get a much smaller blocksize than 512B? I have tried lowering BLOCK_SIZE to 128 and 64 but I get a Bus Error each time I try to encrypt data.

Any help would be very much appreciated! I need to get the size of my data packets much smaller than 512B. I believe XXTea should support variable block sizes, so I'm hoping this is possible!

Thanks!

Try to set
#define CRYPT_ATONCE_SIZE (BLOCK_SIZE / 4)

It is in words, not in bytes... I hope that helps.
