(moderator please change my email address so spammers can't use it.)I've got an odd sort of a question for your group.When I was a kid, my friend's dad had a phone in his house that he told mewas a "scrambler". It was a regular telephone, mounted on a metalbase, with an AC cord for the base. The base had just two vacuum tubes init, and a couple of transformers. It didn't look like much, but my friendsaid his dad used it to make scrambled phone calls to his reserve unit.Has anyone ever seen anything like that? I never knew if he was yanking mychain or not.Ernie Donlin***** Moderator's Note *****If you want me to obfuscate your email address, PLEASE put"[obfuscate]" (without the quotes, but with the brackets) in the*SUBJECT* line of your post. Thank you!Bill HorneModerator

READILY available as a _hardware-based_ attachment. Circa $1k per phone. "compatible" with similar units for landlines.

Skype uses AES-256 encryption, and it is available on some smartphones, but I am not sure if the smartphones support the encryption or not.

There are some flaws with it too:
