You know, if the people wanted it, they could have it on their own, with no big deal.
Ten or so geeks invent Really Lousy Encryption.
It encrypts text, with a twenty letter encryption key. It has no other features, but operates with a cut and paste from any old email program and outputs to a screen only format, which must be cut and pasted to save. You and your friends agree to your key on the phone, or in snail mail.
Everyone gets a copy free, but can send the ten geeks a dime, if they want. Those of you with really big deal aspirations toward blackness set up a one time pad with an automatic new pad every x letters. Anyone who wants buys a copy of the ten geeks Really Fuckin’ Great Encryption program, and use full sentences as your keys.
Now, if anyone with even minor league chops wants to hack your email, they can, in just a few minutes with gee whiz computer or even a few hours with a normal desktop, and some good software.
But if 60 percent of all text based email gets encrypted, and some is not done with RLE, but rather is done with RFGE, no one can tell which is which, and not even the Three Letter Acronym guys can hack a hundred million encrypted messages a day. So, you have increased the total noise to signal ratio of the internet by a factor of millions, and it just can’t be managed by folks that want a peek, legally or illegally.
By the way, the illegal hacker base is profit driven, and adding this sort of overhead to their lives will make them look for a better scam than hacking email.
