Different Hashes

My latest Git commit hash was:

5ba786fcc93e8092831c01e71444b9baa2228a4f

You may have noticed that even though we (you and I) both have the same content in our repositories, we have different commit hashes. While commit hashes are derived from their content changes, there's also some other stuff that affects the end hash. For example:

The commit message
The author's name and email
The date and time
Parent (previous) commit hashes

All this to say that hashes are (almost) always unique, and because they're generated automatically for you, you don't need to worry too much about what goes into them right now.

Note: Hash = SHA

Git uses a cryptographic hash function called SHA-1 to generate commit hashes. We won't go into the details of how SHA-1 works in this course, but it's important to know because you might also hear commit hashes referred to as "SHAs".

Which does NOT affect the hash of a commit?
