It doesn&#x27;t seem very likely that anyone has broken a modern symmetric cipher like AES or ChaCha. If not, a small random key is just as good as a one time pad, and you can reuse it for as many messages as you want. The bigger risks are that you reveal the key or that your hardware is evil, but OTPs don&#x27;t save you from either of those.<p>With <i>public key</i> crypto it&#x27;s a lot more likely that something might be broken. But then again if you somehow solve the problem of swapping secret keys&#x2F;OTPs with everyone you want to talk to, you don&#x27;t need public key crypto.
