But one-time pads aren't impractical like they said?

[–] emergencyfood@sh.itjust.works 5 points 9 months ago

One-time pads are impractical because the sender and the target need to meet up beforehand and agree on a code, and no one else should know this code. With modern encryption, this is not necessary. The target can come up with both the encryption and decryption algorithms, and send only the first to the sender publicly.
