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.
Not the password. The key. The entire key (excluding metadata) is

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