> How much different from MD5 can that be?
Answer: Very.
(MD5: 128 bit | SHA256: 256 bit) ::
(2^256/2^128 = 2^128) => 3.40282367*10^38 of a larger keyspace.
I know nothing about the specifical implementation details of either hashing method (and I eagerly await tptacek to offer a far more comprehensive response) but I'm sure the difference in keyspace alone is enough to make this practically impossible.
