Hi, If you are looking at nos. then you can use ^ operator. For strings, you need to first convert them to bytes,
ASCIIEncoding enc = new ASCIIEncoding (); byte[] keybytes = enc.GetBytes (key);here key is of typestringonce you have converted to bytes, you can work on them. Hope this helps. Cheers Kannan -

Besides the above suggestion, you can after this, create a BitArray with the byte[] and use its Xor method. I see dumb people

You need to ^ each byte, not the whole lot. You need to step through the strings, and can only perform the operation on the set of bytes that exists in both arrays, so unless the two strings are always the same length ( which they are not in your example ), I doubt you're going to get what you wanted.

Again, you can screw up a C/C++ program just as easily as a VB program. OK, maybe not as easily, but it's certainly doable. - Jamie Nordmeyer - 15-Nov-2002 -

You will have to iterate the array and do the operations individually on every byte.
for(int i=0; i<10; i++) kb1[i] ^= kb2[i];Cheers Kannan -

Yes, there is apparently heaps of encryption/decryption stuff in .NET, but I confess to not having used any of it, yet. Christian No offense, but I don't really want to encourage the creation of another VB developer. - Larry Antram 22 Oct 2002
