You may want to look into XOR encryption, it is very simple, yet highly effective.
The basic idea is:
char ^ key_val = encrypted_char

Coincidently, I wrote a simple program that implements this...

Thanks for the reply man, but I have just found out what the problem was: no "fflush(stdout);". I kicked myself after realising that I overlooked this. :)

I have made a little program that works similar to cat, but it also decrypts/encrypts the stream, as well as printing to stdout. It does this by simple XOR encryption.

The reason for the numbers being the same, if I am not mistaken, is due to the fact that srand(time(NULL)) will set the random seed using the system time (in seconds). As you are calling it twice in...
