Generally, we wouldn't want to keep strings as a plain text. A frequent strategy is to use a crypographic hash function to make the plain text password unreadable. A hashing function will replace the input with a different string or number. It is very difficult to go backwards from the hashed value to the original string, but every time we hash, we get the same value.

Use the hash$2$ function on the password: "Chincilla". Demonstrate that each time we use it we get the same value by calling it twice $($remember that only the last line of a cell will print out$).$
