Placeholder-characters Memes

You know you've been reading too much cryptography documentation when you start spotting Alice and Bob in the wild like they're celebrities. For those blissfully unaware, Alice and Bob are the legendary placeholder characters used in literally every security, encryption, and networking example since the dawn of time. They're always exchanging keys, sending encrypted messages, or getting eavesdropped on by Eve. Here you are, lonely dev sitting by yourself, watching Alice and Bob do their thing in yet another RFC or textbook. They're out there living their best cryptographic lives while you're just trying to understand why your SSL handshake is failing. The loneliness is real when your only companions are hypothetical entities from protocol specifications. Fun fact: Alice and Bob were first introduced in a 1978 paper by Ron Rivest, Adi Shamir, and Leonard Adleman (the RSA crew). Before that, cryptographers just used "A" and "B" like absolute psychopaths. At least now our abstract examples have names we can emotionally attach to.
