Already done, actually. Homomorphic encryption systems let end-users perform specific kinds of computation on ciphertext to produce an output which, when decrypted, yields the result of doing those operations on plaintext. Unpadded RSA is partially homomorphic; however, (a) it's not homomorphic in the ways that would be useful to this problem, and (b) it's stupid to use unpadded RSA and the OpenPGP spec prohibits it. But, yeah. Homomorphic systems exist, and they support really weird things like this. But OpenPGP isn't a homomorphic system and thus all this talk is of no real utility to us. But they're *cool*, darn it all. :) _______________________________________________ enigmail-users mailing list enigmail-users@enigmail.net https://admin.hostpoint.ch/mailman/listinfo/enigmail-users_enigmail.net
