comment How are private keys stored on disk?
This question appears to be off-topic because it is about software products (which happen to use crypto, but the question isn't related to the crypto).

comment Spurious keys filter
I'm not sure I understand the question. Are you looking for keys that would map a given plaintext to some ciphertext containing only printing characters? Or for keys that would map any plaintext consisting only of printing characters to a ciphertext consisting of only printing characters? What do you mean by “spurious keys” (are you sure you're using the right English word here?)? Are you using “confusion” in the technical sense, and if not what do you mean? Where does key derivation come in?

I don't understand your last sentence. What do you mean by “use the less private keys”? Could you give an example?
