How is this even possible btw? Doesn’t the private key have to match the public key? Surely this would have been noticed earlier if it had a short public key as well?
Cryptographic hash functions are functions that take a variable-length input and return a fixed-length output, which can be used in, for example, a digital signature.

They use Cryptographic hash functions, so the actual key length is not reflected in the resulting hash length.
