i think it's more that there is a way to produce a collision while altering the file being hashed. this way, you could introduce something into a file and the hash would verify ok. my synopsis may be incorrect as i am not a cryptographer. MD5 hashes have been used to check uniqueness of data on very large scales. it may well be quite sufficient for your needs. you can also use SHA1, but that it produces a larger digest [which may or may not be an issue]. -- \js oblique strategy: remember quiet evenings _______________________________________________ Boston-pm mailing list Boston-pm@mail.pm.org http://mail.pm.org/mailman/listinfo/boston-pm
