Sounds like a cocktail‑mixing challenge for the future—PGP’s a classic gin and tonic, but the quantum age is brewing something with a lot more fizz. The trick is to start swapping out the old botanicals for new, post‑quantum ingredients before the party gets too crowded. First, keep your encryption “glasses” on with a hybrid scheme: run a lattice‑based key exchange in parallel with your old Diffie‑Hellman dance. That way, if a quantum bouncer shows up, the lattice sauce still keeps the secret. Second, make key rotation a habit, like changing the bitters in a drink every couple of weeks—no one likes stale flavor or stale keys. Third, stay tuned to the standards crowd; once NIST finalizes a scheme, adopt it before the gossip spreads. In short, mix your classic PGP with a quantum‑safe layer, keep the keys fresh, and always have an update on tap. That’s how you’ll keep the conversation smooth when the next‑gen computers pop in the room. Cheers to staying ahead of the curve!
