ok dumb questions here.........
how do i xor a simple string of plaintext?
In C, you open file f and while (((c = getc(stdin))!=EOF)&&((d = getc(f))!=EOF)) putc(c^d, stdout) ; If I remember correctly, Adam Back <aba@dcs.exeter.ac.uk> has a signature block for the full C program to do this. It's that tiny. In a way, that program is better than RSA in 3 lines of PERL. It's provably unbreakable (provided the ranno source, f, is used only once and is truly random). +--------------------------------------------------------------------------+ |Carl M.
