Being one-way means you cannot construct the hashed object from the hash. The object will always result in the same hash (provided the same hashing algorithm [https://en.wikipedia.org/wiki/Cryptographic_hash_function] is used )

A hash is a one way encryption of data into a fixed-length string. When the hash length is big enough (e.g. 32 bytes) it is virtually impossible that any data-object can have the same hash has as any other object.

Being one-way means you cannot construct the hashed object from the hash. The object will always result in the same hash (provided the same hashing algorithm [1] is used )
