I remember finding an old BYTE magazine from the 80s while I was cleaning out the crawl space and thought "Oh this should be fun!" expecting a nostalgic tour of ancient systems.
But the feature article was on the RSA algorithm, explaining it in simple terms using an example involving low primes you could then scale up. It was public key crypto for dummies, but it left me understanding enough to encrypt/decrypt a message from first principles by writing a short Python script. I was like holy shit that worked!
