If everyone involved will have both the public and secret daily keys, I don't see the need for using public cryptography. Just generate all those daily keys¹ as a random 128 bit passphrase each and use a symmetric cipher such as AES.² It is actually an interesting contemporary phenomenon:

Thank you, Peter. My question is purely about the security of the encryption. There is no need in my proposed scenario for extra signing or overhead. Understand that I am suggesting the creation of a set of keys, one per day, less than 33 keys, generated by one central admin. Second, i am

Thank you for your excellent response. I laid out my scenario. >> RSA keys have the default maximum length of 8192 set at compile-time. >> Perfect. that was the answer that I was looking for. My "risk scenario" was an attempt to understand the maximum defaults of the current maximum protection

Summary -- Maximum standard pubkey plus seckey pair length is what I'm asking about. Let me continue by explaining some back up information for my question. - I am asking in terms of the latest standards implemented in distros and Windows .exe auto-install packages. - I am trying to create a
