hmac

HMAC stands for "hashed message authentication code". It is like a secret code that is used to keep your information secure. It is like putting a password on a message so that no one else can see it. HMACs use something called "hash encryption" which basically makes the message unreadable by anyone except people who know the secret code. It is like having a locked box that you can only open if you know the right combination of numbers and letters.
