Any algoritm can be reproduced, yes, but a strong random number source
cannot.  See my other email for an example of such.

If the algorithm is strong enough, the only method is a brute force search
of the entire keyspace, which in the case of a 2048 bit key would take
much longer than the age of the universe, even using a billion times the
total computational power of the earth.  Simple algoritms are subject to
frequency analysis and other more subtle analysis.  Pick up a copy of
"Applied Cryptography" by Bruce Schneier for a generaly overview of the
field.
