Sure thing, mate! Here's an example of a SHA-256 hash:

6dcd4ce23d88e2ee95838f7b014b6284a5a5e699c9e53da892178831a01b8de9

It's a string of 64 characters, made up of numbers from 0-9 and letters from A-F. This is the SHA-256 hash of the word "hello".

Neat stuff, huh? But remember, it's one-way - you can't get back to "hello" from this hash. That’s what makes it secure.
