Triple DES can be implemented in at least two different ways, that I
am aware of. Key #1 = key #3 with key #2 being different = 112 bits (2 *
56 bits). "True" triple DES is keys #1, #2, and #3 all being different
from each other = 168 bits (3 * 56 bits). How vendors get to different
lengths is interesting to me.
Thanks.
