I have a keylog file that I captured and it is encrypted by the virus. It
requires a XOR operation of each byte. I would like to see what the contents
of the file is so I know if I lost anything.

I looked in Excel and there is no XOR operation or function.

An example of the file is hex code:

03 34 3e 3b .....

I'm told that if I XOR it with the key, I can get to the data. I found the
key... Can I do this in Exel?

Thanks!
