The gold standard 30 years ago was PGP. RSA 1024 or 2048 for key exchange. IDEA symmetric cipher.
This combination is, as far as I am aware, still practically cryptographically secure. Though maybe not in another 10 or 20 years. (RSA 1024 is not that far from brute forcing with classical machines.)
