CRYPTO4U: Shanghai Man: CZ is wealthiest Chinese person with $90B, NFT yachts, and MonoX hacked

I am introducing cryptography. Cryptography is used to secure and protect data during communication. Encryption is a process which transforms the original information into an unrecognizable form. Decryption is a process of converting encoded/encrypted data in a form that is readable and understood by a human or a computer.
