Hash info is a unique identifier that is used to verify the integrity of a file. It is a string of characters that is generated by a mathematical algorithm, and it is unique to each file. Hash info can be used to check whether a file has been modified or corrupted, and it can also be used to verify the authenticity of a file.
There are many different ways to check hash info, but the most common method is to use a hash checker. A hash checker is a program that can calculate the hash info of a file and compare it to a known good hash info. If the two hash info values match, then the file is considered to be authentic.
