Answer 1

MD5() generates a hash, not an encrypted string. Thus you can’t decrypt it in principle. But studies shown that MD5 is hackable, but it seems too complicated to study.
From “MD5 considered harmful today” @ http://www.win.tue.nl/hashclash/rogue-ca/:

The cryptographic operation that uses a private key to sign data does
not deal directly with the data itself, but with a purportedly unique
representation of this data, that has a predetermined fixed length, is
short and therefore convenient to work with. This can be compared to a
fingerprint as a purportedly unique, short and convenient
representation of a human being. The process of creating such short
representations of data is called “hashing”. Unfortunately, because of
the fixed length of the hash, there must exist pairs of different
inputs that yield the same hash value. Good hash functions, however,
have the property that finding such pairs is extremely difficult, even
though they are guaranteed to exist. This is precisely where MD5 has a
crucial weakness.
