Actually, now when I think about it, your algorithm is much worse than that. Since you only encrypt a byte at a time, and the sequence of random numbers is fully known, you effectively only have a 8-bit XOR cipher. Not only is brute force viable, but even manual brute force BY HAND is viable since you effectively only have an 8-bit key and thus 256 combinations to manually examine.
