You cannot decode a hash. This is the purpose of hashes.
Note that a 512-bit hash is not unique, when it is calculated for a message with 513 or more bits.

Yes, even after relaoding the above comment is still there. Strange! So I try it again:
@Walter: Yes, you are right. My message is really too sloppy. A short message can be reconstructed from the hash, but this consumes much time and a brute-force-attack is a fair approach. But decoding is not the intention of hashes.
Using "purpose" as synonym for "not the intention" was not smart.
