What does hash mean ?? Details

Hash is usually translated as "Hash", which is also directly translated as "Hash", that is, input of any length (also called pre- ing, pre-image ), the hash algorithm is used to convert an output with a fixed length. The output is the hash value. This type of conversion is a compression ing, that is, the space of hash values is usually much smaller than the input space, and different inputs may be hashed into the same output, instead, it is impossible to uniquely determine the input value from the hash value. Simply put, a function compresses messages of any length to a fixed-length message digest.
