#Day4 🔐 Recap first , students proved the foundation is holding. Then @TECH_GUY__ led a lab on Encryption and Decryption. Real messages. Real ciphertext. Real tools. From Caesar cipher to modern encryption, history came alive. Powered by @CiscoNetAcad learning resources .

Confidential Balances use homomorphic encryption, which means the ciphertext itself can be operated on. Your encrypted balance can be debited and credited without ever being decrypted, so the math that updates your account happens entirely over encrypted values. The plaintext amount only exists on the two devices holding the decryption keys.
