comment Strategy for random CTR initial counter values
@RichieFrame While the device can receive and verify signed messages, it needs to be able to emit encrypted messages without having to wait for the control server.

comment RSA decrypting of a huge file by parts
Your question is not clear: are you designing a storage format for that file, or do you have the encrypted file already stored? If the latter, you need to tell us how that file was produced. As the answers here explain, what you're describing, with a huge file somehow encrypted with RSA, is highly atypical. RSA only lets you encrypt a few hundred bits at a time, and slowly, so it's normally used to encrypt a symmetric key which is used to encrypt the rest.

comment Given $n$ bits, how many “truly random” sequences/numbers can be constructed?
@NeilSlater Indeed, I inverted the meaning of pass/fail midway (pass = have the correlation property vs pass = look random). I've reworded that sentence.
