Basically, (it may be the converter I used) but doing the same string results in the same SHA-512 hash.

first of all , Hashes cant be cracked , hashes are one-way-math , its not like Symetric or Asymetric algorithms that can be decrypted , the way it gets cracked is creating exact the same hash , its used huge dictonary list

As Zerocode said, you have to know the differences between a "cipher" and a "hash". Hashes are "meant to be the same every time".
For an example if you "hash" a string today, the hash will be the same tomorrow. Hashes are mostly used for verification etc.
