Suppose you do this:

You store a large file called large.zip on a USB drive.

You compute the SHA$-256$ hash of large.zip, and put the hash in a file called hash.txt on the same USB drive. There is no encryption or password protection on either file or on the USB drive itself.

You unplug the USB drive, and then accidentally leave it on a table at a coffee shop.

The next day, you go back to the coffee shop and retrieve the USB drive from the staff; someone had found it and turned it in$.$

You plug in the USB drive again, and see files called large.zip and hash.txt$.$ You compute the SHA$-256$ hash of large.zip, and find that the result is the same as what's in hash.txt$.$

In step $5,$ can you be confident that the contents of large.zip are the same as they were in step $2?$ Why or why not?

Your answer should be "yes" or $"$no$",$ followed by one sentence explaining the reason.
