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

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…

It is currently said that MD5 is partially unsafe.
Taking this into consideration, I'd like to know which mechanism to use for password protection.
Is “double hashing” a password less secure than just hashing it once?
Suggests that hashing multiple times may be a good idea.
How to implement password…

I'm looking at hashing algorithms, but couldn't find an answer.
Bcrypt uses Blowfish
Blowfish is better than MD5
Q: but is Blowfish better than SHA512?
Thanks..
Update:
I want to clarify that I understand the difference between hashing and encryption. What prompted me to ask the question…

When I use C# to implement the AES symmetric encryption cipher, I noticed:
PasswordDeriveBytes derivedPassword = new PasswordDeriveBytes(password, saltBytesArray, hashAlgorithmName, numPasswordIterations);
Why do I need to use a hashing algorithm for AES encryption? Aren't they separate? Or is…

So i implemented a Quad tree in Java for my 2D game and everything works fine except for when i run my collision detection algorithm, which checks if a object has hit another object and which side it hit.My problem is 80% of the time the collision algorithm works but sometimes the objects just go…
