The algorithm was fine. The main reason your initial code produced the
wrong result seems to have been that the hex() function did the opposite
of what you expected.
However, doing it yourself is inefficient and open to errors, such as
using functions which do the opposite of what you intended. Increasing
your familiarity with the language allows you to choose more efficient
and less error-susceptible, not to mention simpler and clearer,
alternatives.

The same is true of both Java and C/C++. While I'm a Perl junkie
myself, I have written web-based apps in low-level C and I hear there
are 1 or 2 people out there using Java on the web, too.
