h1. General approach
Each file the user want to share is cut sequentially in pieces called _chunk_. Each chunk has the same size except the last one which can be smaller.
For each chunk there is a footprint called _hash_ which identify the chunk. We admit that two chunks with the same hash contains the same data. The hash is computed with a cryptographic hash function like SHA-1.
