hashing

Hi fellas,

A) Are there any FOSS programs out there that can manage to hashchange all files in a directory tree?

B) Failing that, what methods could be used to develop this capability in a (crappy) self-written program without requiring the program to be sophisticated and content-aware? Is there any (roughly) universally safe location within a file (for example, around EOF?) where on could one simply append/add psuedorandom data so the resulting hash is different? Is there a better/more elegant solution?

Muchos gracias

Hi, I would like to construct a hash table that looks up keys in sequences (strings) of bytes ranging from 1 to 15 bytes.

Theoretically does hashing a unique value yield a unique value? Let's say I have a DB table with 2 columns: id and code. id is an auto-incrementing int and code is a varchar. If I do ... $code = sha1($id); ... and then store $code into the same row as $id. Will my code column be unique as well… >>> More

I want to hash "user + password". EDIT: prehashing "user" would be an improvement, so my question is also for hashing "hash(user) + password".
