Can you hash a file?
One method you could use is called hashing, which is essentially a process that translates information about the file into a code. Two hash values (of the original file and its copy) can be compared to ensure the files are equal.

What is the purpose of a hash?
Hashing is mapping data of any length to a fixed-length output using an algorithm. Typically, the hashing algorithm most people know of is SHA-2 or SHA-256. That’s because it’s the current standard for SSL encryption. The purpose of hashing is authentication.
How do I run checksum on Linux?
To run a checksum on a file is simple. Just evoke md5sum followed by the name of the file. Here we generated a checksum of a text file containing all 185 lines of the short story Harrison Bergeron by Kurt Vonnegut. If we edit the file and change one character, the checksum will change.
