I have an AES256 key in hexadecimal "8A64E947DAA12B6B7761F30192219270883F24D358D55A1E98E5364B801E9120".
That key is encrypted in AES256 and have to decrypt the following key and initialization vector:
Key = "517565747A616C636F61746C5349495038383838383838382020202020202020"
IV = "00000000000000000000000000000000".
The result of the decryption must be a string of 64 characters (hexadecimal).
