I am looking for a solution to the following problem...
I have 2 machines each with the same initial string value (aka key). On each of the systems I want to encrypt the strings on both machines in such a way that after the encryption their values are the same, and to be able to encrypt each of them over and over again with equivelent results on both machines.
So, I guess my fundamental question is - "given the same plain text starting point, does any specific encryption algorithm encrypt to the same value each time?"
Thanks very much for your help.
