The critical phrase is this one: "If the key is truly random". Very difficult to avoid patterns and be truly random.

One-time pads sound in theory pretty cool, but are not very useful for our purposes:

  1. as oaxaca already said, it's REALLY hard to create true random numbers
  2. you need to securely(!) get your pads to all parties involved, so you need a second (secure) channel for that. Think 2FA via your mobile or similar, but with security.
  3. You can use a pad only one single time, so each message needs a new pad
  4. when an attacker gets your pad it's useless, she can decrypt your message very easily (easily as in "with a piece of paper and a sharpie)

Especially 2. above is the weak point, if you have a channel secure enough to transport your pads you could as well use it for your original message.

How would we even use encryption? Darksend strength does not come from encryption at all.

  1. you need to securely(!) get your pads to all parties involved, so you need a second (secure) channel for that. Think 2FA via your mobile or similar, but with security.
Encrypt the pad using RSA-2048 or RSA-4096.
