Disregarding keyloggers and trojans, if I gpg encrypt multiple different files with the same passphrase do those files become in any real way easier to brute force or somehow crack.

I would not be asking this question if it were not for the recent software exploits which occurred due to false randomization. My concern is that having multiple different files encrypted with the same passphrase will not simply make the passphrase incrementally or X times easier to guess, X being the number of files, but exponentially easier to guess.

Please only answer if you are certain.

Only if the attacker has some clue about file contents, not if you are encrypting pseudorandom bytes
