Project 3 hash question

[kai...@gmail.com]

When running ./hash and providing a password, is it supposed to output 8 digits or can it be less? Some values I am trying to hash are giving me only 6 characters instead of 8.

Check the source code.

The hash is a 32 bit number. When printed in hex you get characters, but the characters are just a representation of the 32 bit number. How many digits should the HEX representation of a 32 bit number have?

Yes, it outputs a fixed 32 bit result. Not variable. Human readable result is different.

Suppose the output of the hash function is 32 bits of zeros. All zeros. That is a fixed 32 bit result.

However what would be the output if printed with %d (decimal, or %x (hex)?

I thought that hash functions output fixed length values. If they are variable I don't see how to make the rainbow table work?
