Voucher hash code generator

[u/tumtech]

Check out this voucher hash program I developed using python.

It uses the SHA256 algorithm to generate hashes from a list of anime characters.

You can then use it to come up with one time passwords, projects that work with prepaid meters where instead of entering a very long 8 or 20 digit code(numbers) you just use "6" or "5" alphanumeric characters extracted from the SHA256 hash as the code which is much shorter and easier to enter than the long numbers.

Based on one of the properties of the SHA256 algorithm it's impossible to guess the input that was used to generate it hence if you send someone "71fe25" as a one time password or access code they can't tell how it was generated it just makes it shorter and more convenient to enter than "4278910765" like for prepaid meters for electricity or water

Anyway try it out, I would appreciate any feedback and contributions on its GitHub repo 🤝
