You /do/ realize that an MD5 value is *not* an encryption of data, but a
'checksum' (a 'Message Digest', in fact), don't you?

This means that there's no way to reverse an MD5 value into the
plaintext that was used to generate it, for the same reasons that you
will never be able to reverse the value 35 into a well known passage
from the Old Testament of the Bible.
