Saw Alice And Bob Again

Saw Alice And Bob Again
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.

The Future Of Mallory

The Future Of Mallory
Ah, the classic cryptography trio! In security modeling, Alice and Bob are the standard characters who want to communicate securely, while Mallory is the malicious attacker intercepting their messages. But here, poor Mallory has been replaced by The Atlantic magazine—implying they're now the ones snooping on everyone's conversations and spreading them to the world. Journalists: the new man-in-the-middle attack! Ten years in cybersecurity and I still can't decide which is more dangerous.
