I don't fully understand hashing algorithms. Anybody care to explain it to me in a very simply understandable way.

Thanks

Is hashing of just "username + password" as safe as salted hashing

I want to hash "user + password". EDIT: prehashing "user" would be an improvement, so my question is also for hashing "hash(user) + password". If cross-site same user is a problem then the hashing changed to hashing "hash(serviceName + user) + password" From what I read about salted hash, using… >>> More
