I have a hash and what I think is its original value

I know this hash is some of this values above and think that 20030130 should belong to99b9e76825dc15ca02319b9ac513e84e48a38364c218918403c224bc4ff57e48

so how can I figure out if 20030130 (because there are only numbers and its short) belongs to any of this hashes and possibly hash it in such a way I get one of this hashes for it

Thanks for Anwsering and Best Regards

Just plug it in any SHA256 hash-algorithm calculator and see! You can do this online or use a simple Python module like hashlib to hash things on your own.

Using both the online program and a simple python3 script I wrote, 20030130 doesn't match any of the hashes listed (instead producing the hash 8fbaf5a8fedcebe1214b6fd23bec5db357ba4f6323630a1d59ffe86d948f0b81). There is a good chance a salt could be being used, which means the hashes would have a different word prepended that makes cracking a hash more difficult.

  • but its a very old program: winradio.com/software/drm_software_radio_2.0.38.zip, I don't think they used salt in 2004 also how can I figure what hash algo is used here is the function that should calculate it: pastebin.com/EHq1fFJr Commented Aug 29, 2019 at 17:15
  • Salts have been used since before the 1980s. If your question is "how do I know what hash algorithm this is?" that's an entirely different question and you should update your question accordingly. What hash algorithms have you tried? Commented Aug 29, 2019 at 19:07
  • SHA512, SHA384, SHA1, MD5 after using SND Reverser tool said they are used Commented Aug 30, 2019 at 21:27
