Actually what I'm trying to do is store 1000 bitcoin private keys+addresses. That takes about 90kb or so.
What's stopping you from using BIP38 on each private key?The great benefit of printing individual private keys is that you can simply decrypt only one of them, while keeping the rest in cold storage. And you won't lose all of them if you can't read all pages.
You know that makes sense. I think that's a much better way actually than my idea of encrypting them all in one big blob.

Even better if you create all of the keys from a HD seed, and store that seed separately.
Understood.
