comment State of the art RSA key generation
This doesn't answer the question at all. It isn't asking for a basic explanation of RSA, it's asking about what constraints on the two primes must be checked to avoid security pitfalls.

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?
