Cryptography: Hashing, Encryption & How We Keep Data Safe

Here we dig into how cryptography protects our data from hashing passwords to public key encryption. I break down how hashing works, why we add “salts” to keep things secure, and how even leaked passwords aren’t as useful to attackers as you might think. We also step back in time to look at the Enigma machine and classic ciphers, before fast-forwarding to modern techniques like RSA, Diffie-Hellman, and how cloud providers manage encryption keys behind the scenes. It’s a practical crash course in how we keep sensitive data locked down, online and off. #cybersecurity #hashing #encryption #cloudsecurity #computerscience
