molecular weight prediction s/w

Hi all.

I'm looking for a program that will predict the mass and sequence for all 
possible peptide fragments from a given protein sequence.  Can anyone
point me towards such an algorithm?

(I've done a trypsin digest of my protein of interest, and separated the
fragments.  MS on one protein peak gave an apparent mass of 829 da.  I now
want to figure out what amino acid sequences would be consistant with that

Thanks for any help you can give me.
