This mailing list is about implementation of cryptosystems in linux, and
is not as much about security of any single cryptosystems, unless it is
included in or planed to be in the linux kernel or linux application. So
your question is not that terribly on-topic. Other places would be more
appropirate, and more likely to give you a better answer, if that is
what you want. The sci.crypt newsgroup is one such place.
Also, If this is to be taken seriously, you need to give more details,
like the algorithm, encoding scheme and other details of your system. A
basic assumption is cryptology is that the adversary know everything
except one piece of secret information - the key you used for
encryption. The history has proved that such information almost always
leaks out or are reverse engineered anyway. It is known as "security by
obscurity". Even if you think your system is secure with all detailes
published, but don't do it "just in case", you are still limiting the
number of people that can analyze the system. The GSM mobile phone
encryption (which is broken) is an example of such a system.
Since the question implies that you lack some knowledge in crytology, I
would recomend to buy some books on the topic. Bruce Schneiers "Applied
cryptography" is one such book. The book "Handbook of Applied
cryptography" (Menezes et al) is a little bit harder to read, but is
freely downloadable on the net (http://www.cacr.math.uwaterloo.ca/hac/).
Both of them are a little bit old (both 1996 i think), but still covers
the basics. They lack some of the newer algorithms though.
(BTW: On sci.crypt you would be flamed to charcoal with a question like
yours)
