Well, I just modify the "specifics" because I don't have time to re-structured all the proposal. Thank you for those precisions. I join the skeleton library I coded few days ago. EDIT : I couldn't join it because the message exceed 75KB, so I uploaded it, please download the file with the following link : http://www.mediafire.com/file/0odobkg11p2uvda/checks_hashes_project.zip 2011/4/8 Pierre Talbot <pierre.talbot.6114@herslibramont.be>

You mix four distinct things in one: ISBN/EAN/VISA/etc, for catching human-entry errors; hash functions as in hash tables, which only care about distribution; checksums like CRC32, for catching data transmission errors; and cryptographic hash functions, the only ones useful against malicious adversaries.
The summer is short, and the boost process is long. I'd encourage you to look only at the first category. As you mention, it's the one with the fewest alternative libraries, so you won't have to prove competitive performance and such, and there are no real security issues to deal with.
Also, I'd like to see some sketches of interfaces. What do you expect user code to look like?
A few specifics:
"This kind of drama situation can be avoided by storing encrypted passwords." Encrypted means cyphers, not hashes. You want digests or MACs of passwords, not something reversible.
"Write, test and document the hash functions MD5 and SHA-1 256 bits." There's no such thing as 256-bit SHA-1. Do you mean SHA-256, from "SHA-2"?
Also, MD5, SHA-1, and SHA-2 are implemented in my hash library: <http://svn.boost.org/svn/boost/sandbox/hash/boost/hash/md5.hpp> <http://svn.boost.org/svn/boost/sandbox/hash/boost/hash/sha1.hpp> <http://svn.boost.org/svn/boost/sandbox/hash/boost/hash/sha2.hpp>
