I bought an HWRND last week. What do you think, how secure is the encryption with that and the OTP? See the OneRNG theory of operation here.

    $\begingroup$ Then how are going to store the OTP key? Do you really know how the One Time Pad is working? $\endgroup$

    $\begingroup$ I think the issue kelalaka is taking here is the fact that while you can use that RNG for OTP (-like) encryption this doesn't solve the issue that now you have an encrypted file and a key as large as that file and you now have the same problem as originally: You have sensitive data that you want to protect, but this time it's the OTP key instead of the plaintext. $\endgroup$

    $\begingroup$ @SAIPeregrinus This is not a "rare" use case. It's the de facto usage for OTPs. Hiding 8K UHD films is not. History has proven that over and over and over. You pre-share the keys before mounting an operation. War can be declared in a text message, and 1 MB ~ 6,000 messages. $\endgroup$

    $\begingroup$ I'm saying that the case where OTPs are usable is rare out of all the cases where encryption is useful. Not that the opportunity to pre-share key material is rare when using OTPs, that would be dumb, since it's required to use OTPs. $\endgroup$ Jul 2 at 13:26
