Really Dumb



Crypto is short for cryptography, which is the practice of using special codes to keep information safe. For example, a secret message might be written using a code that only you and the person you are sending it to know. That way, no one else can read it. Cryptography is used a lot in everyday life. For example, when you make a purchase online, like shoes or a video game, your credit card information is encrypted so that no one else can access it. Another example of cryptography is when you use a password to log into a website or app. Your password is encrypted so that only you can access your account. Fun Fact: In World War II, cryptographers helped break German codes, which helped the Allies win the war.
