Of course entropy theoretically makes a password stronger but from the perspective of a password cracker the first password likely would take much longer to crack. This is because of the length of the password--this argument would probably not be valid with a short password. It is something I have written about before myself Consider how password cracking ...

Nope Generally speaking: No. Hashing is not encryption. Hashing is not reversible. At all. It always generates a fixed length output. So with an output fixed to say 32 characters, and an input of 33 characters, there is no possible way to reverse this. The information of that one character is irretrievably lost. -- And along with it all other characters. ...

For "symmetric cryptographic algorithms" (symmetric encryption, MAC...), things are simple: a non-broken cryptographic algorithm is such that it uses an n-bit key, and the fastest method to find the key is trying out all possible keys until the right one is found (that is called exhaustive search or brute force). The algorithm is said "non-broken" precisely ...
