How to find the original value from the keccak 256 hash value in python?

Question

I'm using following code to get the keccak 256 hash:

import sha3
k = sha3.keccak_256()
k.update(b'age')
print (k.hexdigest())

How do I convert the keccak 256 hash value back to original string? (I'm ok with using any library as needed).

Answer 1

You can't convert the hash value back to the original string. The hash function is created in a way that it is infeasible to convert the hash value back to the original string.
